Notes Jeans instability In the interstellar model, molecular clouds are the sites of star formation. Clouds must be in hydrostatic equilibrium for stability, which requires that internal pressure be in equilibrium with …
Notes Optical aberration In astrophysics, optical aberration refers to the distortion or deviation of light as it passes through the Earth's atmosphere or other optical systems, such as telescopes. Optical aberration can …
Notes Magnitude of the star The magnitude of a star is a measure of its brightness as seen from Earth. It is logarithmically based on the amount of light that reaches our eyes from a ...
Notes Radiative energy transport Radiative energy transport refers to the transfer of energy through electromagnetic waves or photons. It occurs as a result of the emission and absorption of electromagnetic radiation by matter, and …
Notes Energy transfer mechanism Local thermodynamical equilibrium:Thermodynamical equilibrium between the gases (neutral, partially ionized, completely ionized) and radiation in which Maxwellian velocity distribution (neutral gas), …
Notes Linear Stellar Model The Linear Stellar Model is a mathematical model used to describe the dynamics of a large number of stars in a galaxy. It uses linear algebra and linear dynamical systems ...
Notes Hydrostatic equilibrium Hydrostatic equilibrium is an important concept in the study of stars. It refers to the balance between the inward force of gravity and the outward force of pressure that determines ...
