The HAT-P-13 Exoplanetary System: Evidence for Spin-Orbit Alignment and a Third Companion

We present new radial velocity (RV) measurements of HAT-P-13, a star with two previously known companions: a transiting giant planet "b" with an orbital period of 3 days and a more massive object "c" on a 1.2 yr, highly eccentric orbit. For this system, dynamical considerations w...
