Tidally induced stellar oscillations: converting modelled oscillations excited by hot Jupiters into observables

Abstract:

We calculate the conversion from non–adiabatic, non–radial oscillations tidally induced by a hot Jupiter on a star to observable spectroscopic and photometric signals. Models with both frozen convection and an approximation for a perturbation to the convective flux are discussed. Observables are calculated for some real planetary systems to give specific predictions. Time–dependent line broadening and the radial velocity signal during transit are both investigated as methods to provide furthe...
