Energy Transport

Energy transport inside a star takes place in three ways: Radiation: dependent on opacity, flux, density, and temperature. Larger opacity and flux involve steeper decrease in T with increasing r. Convection: cool masses move “down” (in the direction of gravitational pull) and hot masses … Continue reading

Stellar Atmospheres

Radiation emitted by a star: Can be measured in terms of the specific intensity. It corresponds to the amount of energy of a given wavelength per unit time dt crossing a unit area dA into a solid angle dΩ (think of … Continue reading
