A simple definition of astrophysics is this is the field wherein the study of physics is applied to the study of the cosmos. It is a hybrid field combining physics and astronomy, and has two subdivisions, theoretical and applied or experimental.
Research in astrophysics addresses a great variety of topics, for example:
- Stars
- - stellar evolution
- - magnetic field properties
- - stellar convection
- Stellar atmospheres
- - nature of spectral analysis
- - electron density
- The Galaxy (the Milky Way)
- - interstellar gas and dust
- Galaxies
- - modeling the environs of galactic-centre massive black holes;
- - the structure and dynamics of galactic bars;
- - the flow of gas into and out of galaxies;
- - the role of active galactic nuclei in limiting the growth of galaxies.
- CMB (cosmic microwave background radiation)
- Astroparticles
- Black holes
- Dark Matter
- Astrochemistry (The role of the chemical bond and organic chemistry in nature on a cosmic scale)
- Over 140 molecules have been identified in the interstellar gas and circumstellar shells. To date the largest is a carbon chain with 13 atoms and a molecular weight of 147.
