The topic of how stars change, or stellar evolution, is often modeled by placing the varieties of star types in their respective positions on the Hertzsprung—Russell diagram , which can be viewed as representing the state of a stellar object, from birth to destruction. Theoretical astrophysicists use a wide variety of tools which include analytical models for example, polytropes to approximate the behaviors of a star and computational numerical simulations.
Each has some advantages. Analytical models of a process are generally better for giving insight into the heart of what is going on. Numerical models can reveal the existence of phenomena and effects that would otherwise not be seen. Theorists in astrophysics endeavor to create theoretical models and figure out the observational consequences of those models. This helps allow observers to look for data that can refute a model or help in choosing between several alternate or conflicting models.

Theorists also try to generate or modify models to take into account new data. In the case of an inconsistency, the general tendency is to try to make minimal modifications to the model to fit the data. In some cases, a large amount of inconsistent data over time may lead to total abandonment of a model. Topics studied by theoretical astrophysicists include stellar dynamics and evolution; galaxy formation and evolution; magnetohydrodynamics; large-scale structure of matter in the universe; origin of cosmic rays; general relativity and physical cosmology, including string cosmology and astroparticle physics.
Astrophysical relativity serves as a tool to gauge the properties of large scale structures for which gravitation plays a significant role in physical phenomena investigated and as the basis for black hole astro physics and the study of gravitational waves.

Some widely accepted and studied theories and models in astrophysics, now included in the Lambda-CDM model , are the Big Bang , cosmic inflation , dark matter, dark energy and fundamental theories of physics. Wormholes are examples of hypotheses which are yet to be proven or disproven. The roots of astrophysics can be found in the seventeenth century emergence of a unified physics, in which the same laws applied to the celestial and terrestrial realms. The efforts of the early, late, and present scientists continue to attract young people to study the history and science of astrophysics.

Plato's Cosmology: The Timaeus of Plato translated, with a running commentary. Indianapolis: Bobbs Merrill Co. Stanford Encyclopedia of Philosophy. Far from being bodies with physical properties to be investigated, the stars were seen as markers measured in order to construct an accurate, detailed and precise background against which solar, lunar and planetary motions could be charted, primarily for terrestrial applications.
The main concepts of modern astrophysics and prospects for future studies are accompanied by numerous illustrations and a summary of the advanced projects at various astronomical facilities and space missions. Marov guides readers through a maze of complicated topics to demystify the field and open its wonders to all. Grabbing the attention of poets, politicians and the general public alike, a series of spectacular astronomical events in the late s galvanized Americans to take a greater interest in astronomy than ever before. At a time when the sciences were not yet as well established in the United States as they were in Europe, this public interest and support provided the growing scientific community in the United States with the platform they needed to advance the field of astronomy in the United States.
Earlier in the 19th century comets, meteors and the discovery of the planet Neptune were all sources of inspiration to the general public. The specific events to be considered here are the total solar eclipses of , and and the transits of Venus of and The available media responded to public interest as well as generating more interest. These events laid the groundwork that led to today's thriving network of American amateur astronomers and provide a fascinating look at earlier conceptions of the stars.
The first five chapters are devoted to classical physics, from planetary motion to special relativity, always keeping in mind its relevance to questions of contemporary interest. The next six chapters deal mainly with newer developments in physics, from quantum theory and general relativity to grand unified theories, and the book concludes by discussing the role of physics in living systems. A basic grounding in mathematics is required of the reader, but technicalities are avoided as far as possible; thus complex calculations are omitted so long as the essential ideas remain clear.
Finlay Published: This book is for the amateur astronomer who wants to know about the astrophysical nature of deep sky objects. The information is presented in a concise format and is equally valuable when used as background reading or, alternatively, at the telescope eyepiece. Coverage here is limited to approximately of the most commonly observed objects in the Northern Hemisphere and - an enhancement for the Second Edition - approximately 50 of those in the Southern Hemisphere. These are visible from the southern limits of the United States as well as from the southern continents.
Viewing and Imaging the Solar System: A Guide for Amateur Astronomers is for those who want to develop their ability to observe and image Solar System objects, including the planets and moons, the Sun, and comets and asteroids. This book is designed to show amateur astronomers, in a relatively light-hearted--and math-free way--how to become serious. Camille Flammarion is considered France's greatest popularizer of astronomy, with over 60 titles to his credit. In , he published his masterpiece, La Planete Mars et ses conditions d'habitabilite, a comprehensive summary of three centuries' worth of literature on Mars, much of it based on his own personal research into rare memoirs and archives.
