#stellar physics
- Astrophysics — A branch of astronomy and modern physics that studies the physical properties, chemical composition, structure, dynamics, and evolution of celestial bodies (stars, planets, galaxies, nebulae) as well as the interstellar or intergalactic medium. This discipline applies the laws of thermodynamics, quantum mechanics, relativity, and electromagnetism to explain complex cosmic phenomena, from stellar nuclear fusion processes to cosmic microwave background radiation.
- Astrophysicist — A woman who works as an astrophysicist; a highly qualified female researcher or specialist in the field of astrophysics who applies physical laws and principles to study the chemical composition, internal structure, orbital dynamics, and evolution of celestial bodies. Her activity involves utilizing high-power spectrographs, interpreting gravitational anomalies around black holes, and developing computational mathematical models to explain the expansion of the universe.
