Various applications of multicolour photometry and radial velocity data for multimode $\delta$ Scuti stars
In addition to revealing spherical harmonic degrees, , of excited modes, pulsational amplitudes and phases from multicolour photometry and radial velocity data yield valuable constraints on stellar atmospheric parameters and on subphotospheric convection. Multiperiodic pulsators are of particular interest because each mode yields independent constraints. We present an analysis of …
