WebFeb 23, 2024 · A star of a given mass and composition has a fixed radius. If you increase the mass you increase the radius. If you fix the mass and make to star more metal-poor, then you decrease the radius (but not by very much for M-dwarfs). The surface temperature is determined by the luminosity and radius. WebThe stellar structure is usually assumed to be spherically symmetric, so the horizontal (i.e. non-radial) component of the oscillations is described by spherical harmonics, indexed by an angular degree and azimuthal order . In non-rotating stars, modes with the same angular degree must all have the same frequency because there is no preferred axis.
