The Radial Velocity Signature of Tides Raised in Stars Hosting Exoplanets
stars: planetary systems – stars: solar type – hydrodynamics – waves – planet-star interactions
2011/10/18
Close-in, massive exoplanets raise significant tides in their stellar hosts. We compute the radial velocity (RV) signal due to this fluid motion in the equilibrium tide approximation. The predicted ra...
