Inferences from pulsational amplitudes and phases for multimode<i>δ</i>Sct star FG Vir
We combine photometric and spectroscopic data on twelve modes excited in FG Vir to determine their spherical harmonic degrees , and to obtain constraints on the star model. The effective temperature consistent with the mean colours and the pulsation data is about 7200 K. In six cases, the identification is …
