Division A is responsible for monitoring the scientific and organizational development of fundamental astronomy and for ensuring that the most significant issues in the field are addressed with foresight, enterprising spirit, and scientific judgment. The Division fosters new initiatives and international cooperation in fundamental astronomy, standardization of scientific results, and promotes investigations and discussions relating to the relevant topics and projects. The scientific community of Division A:

Fundamental Astronomy gives a well-balanced and comprehensive introduction to the topics of classical and modern astronomy. While emphasizing both the astronomical concepts and the underlying physical principles, the text provides a sound basis for more profound studies in the astronomical sciences. The fourth edition of this successful calculus-based textbook and reference includes a wealth of new information and several chapters are restructured for clarity and improved organization. The chapters on radiation mechanisms and temperatures have been combined, and some of the material from the appendices has been redistributed to appropriate places throughout the text. In addition, the chapters on the solar system and cosmology are rewritten to reflect new understanding and tables in the appendix on the theory of relativity have been updated. Long considered a standard text for physical science majors, Fundamental Astronomy is also an excellent reference and entrée for dedicated amateur astronomers.

Fundamental Astronomy gives a well-balanced and comprehensive introduction to the topics of classical and modern astronomy. While emphasizing both the astronomical concepts and the underlying physical principles, the text provides a sound basis for more profound studies in the astronomical sciences. The fifth edition of this successful undergraduate textbook has been extensively modernized and extended in the parts dealing with the Milky Way, extragalactic astronomy and cosmology as well as with extrasolar planets and the solar system (as a consequence of recent results from satellite missions and the new definition by the International Astronomical Union of planets, dwarf planets and small solar-system bodies). Furthermore a new chapter on astrobiology has been added.Long considered a standard text for physical science majors, Fundamental Astronomy is also an excellent reference and entrée for dedicated amateur astronomers.

SOFA, which stands for "Standards of Fundamental Astronomy", is an International Astronomical Union (IAU) [1] service that maintains an authoritative and accessible set of algorithms and procedures to implement standard models used in fundamental astronomy. Included are procedures for precession-nutation, Earth rotation, sidereal time, conversions between time scales, and the chain of astrometric transformations linking star data from a catalog and the observed direction of the incoming radiation; a more detailed list is given below.

This course is an overview which will touch on topics throughout astronomy. Ten percent of the grade will be based on class participation.For the remaining 90%, half of the grade will be based on the homework, and theother half will come from the tests (midterm and final).Problem sets will be assigned (very roughly) every other week. Science is a collaborative discipline, so you are encouraged to work with other students on these problem sets. However, your writeups must be expressed in your own words and not shared with other members of the class. Late homework will be penalized with a 10% deduction in points for each day past the due date. Please DO NOT start the homework the night before it's due!! Come ask me forhelp if you are stuck on any problems.There are two on-line textbooks associated with the class. Both can beaccessed from any Penn State computer. If you are not on a Penn Statecomputer, you can still access the texts via Penn State's GlobalProtect VirtualPrivate Network (VPN). The software to do this can be downloaded at Fundamental Astronomy by Karttunen et al. covers much of the materialof this course (although in a different manner than I do). You can find thebook at -springer-com.ezaccess.libraries.psu.edu/book/10.1007%2F978-3-662-53045-0.Extragalactic Astronomy by Peter Schneider is useful for the latterhalf of the course. It is at -3-540-33175-9.Finally, if you would like to know more about any subject, or want a different slant on things, there are numerous other papers and notes associated with this course. Many are/will be given in the links below, whileothers are included in the class notes.

SOFA (Standards Of Fundamental Astronomy) is a collection of subprograms, in source-code form, that implement official IAU algorithms for fundamental astronomy computations. SOFA offers more than 160 routines for fundamental astronomy, including time scales (including dealing with leap seconds), Earth rotation, sidereal time, precession, nutation, polar motion, astrometry and transforms between various reference systems (e.g. BCRS, ICRS, GCRS, CIRS, TIRS, ITRS). The subprograms are supported by 55 vector/matrix routines, and are available in both Fortran77 and C implementations.

Fundamental astronomy is an essential branch of modern gravitational physics, which explores the fundamental structure of space and time by studying the dynamics of massive bodies and elementary particles, such as photons, in gravitational field on time scales from one orbital revolution to the Hubble time. It establishes basic theoretical principles for high-accuracy calculation and interpretation of various astronomical effects and phenomena observed in gravitationally-bounded systems, for example, clusters of galaxies, the Milky Way, stellar clusters, binary and multiple stars, and the solar system and its sub-systems. It also provides definitions and models that describe reference systems and frames used in astronomy and geodesy.

Fundamental astronomy obtains physical information on celestial objects and investigates physical laws using the methods of astrometry, celestial mechanics and space geodesy which include long baseline radio and optical interferometry, laser and radio ranging, pulsar timing, Doppler tracking, space astrometry, atomic clocks and Global Positioning System (GPS), etc.

A special emphasis should be made on relativistic celestial mechanics and astrometry which are relatively new areas of research in fundamental astronomy that receive special attention in experimental gravitational physics in order. The development of theoretical and observational tools of relativistic celestial mechanics and astrometry are essential for further progress in testing general relativity and direct detection of gravitational waves to bring a deeper understanding of the nature of gravitational field and fundamental structure of the spacetime manifold.

The standard model describes nature on the smallest of scales, comprising fundamental particles known as leptons (such as electrons) and quarks (which can come together to form heavier particles such as protons and neutrons) and the forces they interact with.

What then, could this mean for the future of fundamental physics? If what we are seeing is really the harbinger of some new fundamental particles then it will finally be the breakthrough that physicists have been yearning for for decades.

We will have finally seen a part of the larger picture that lies beyond the standard model, which ultimately could allow us to unravel any number of established mysteries. These include the nature of the invisible dark matter that fills the universe, or the nature of the Higgs boson. It could even help theorists unify the fundamental particles and forces. Or, perhaps best of all, it could be pointing at something we have never even considered.

We define in this chapter the useful constantsfor the understanding of the motion and distance measurementsin the solar system. However, we give the definition of themost fundamental units and constants of astronomy in general.

Foundations of astronomy immerses its reader in the detailed foundational aspects of astronomy. Authors Seeds and Backman, invite readers to look to the skies and ask ourselves some crucial, metaphysical questions: What are we and how do we know what we are? It covers a depth of content while remaining accessible and reader friendly.

Astronomy is for all ages and Rebecca Keller has put together a stellar textbook for middle school astronomy enthusiasts. In addition to learning about the history of astronomy, students will also learn about space probes, telescopes, asteroids, the solar system and much more. It is a treasure trove of information for young minds.

Fundamental Astronomy balances theoretical concepts of astronomy with their basic physical principles. In addition to the fundamental theories, this textbook also contains additional sections on modern concepts including extrasolar planets and astrobiology.

Ryden and Peterson have compiled a comprehensive introduction to astrophysics for astronomy and physics majors. Fundamentals of Astrophysics also contains numerous problems for students to work through to enhance their comprehension of key theories.

This is the best astronomy adult activity book. It includes 44 collaborative activities that often appear in introductory astronomy classes. Students can benefit from extensive resources and in-depth explanations.

Simply put, Astronomy is one of the best textbooks for introductory level astronomy courses. Authors use simple language to contextualise some of the fascinating scientific discoveries and theories in the field of astronomy. Astronomy is made accessible worldwide and has a whopping thirty chapters covering everything from celestial distances to Black Holes and curved spacetime. 041b061a72
