Refined stellar, orbital and planetary parameters of the eccentric HAT-P-2 planetary system
We present refined parameters for the extrasolar planetary system HAT-P-2 (also known as HD 147506), based on new radial velocity and photometric data. HAT-P-2b is a transiting extrasolar planet that exhibits an eccentric orbit. We present a detailed analysis of the planetary and stellar parameters, yielding consistent results for the mass and radius of the star, better constraints on the orbit...
متن کاملTransit Timing Variations and orbital stability
We confirm 27 planets in 13 planetary systems by showing the existence of statistically significant anti-correlated transit timing variations (TTVs), which demonstrates that the planet candidates are in the same system, and long-term dynamical stability, which places limits on the masses of the candidates—showing that they are planetary. All of these newly confirmed planetary systems have orbit...
متن کاملDevelopments in Planet Detection using Transit Timing Variations
In a transiting planetary system, the presence of a second planet will cause the time interval between transits to vary. These transit timing variations (TTV) are particularly large near mean-motion resonances and can be used to infer the orbital elements of planets with masses that are too small to detect by any other means. I present the results of a study of simulated data where I show the p...
متن کاملThe HAT-P-13 Exoplanetary System: Evidence for Spin-Orbit Alignment and a Third Companion
We present new radial-velocity 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 would lead to constraints on planet b’s interior structure, if it could be shown that the orbits are coplanar and apsidall...
متن کاملFourier-Domain Study of Anti-correlated Transit Timing Variations
We present a method to confirm the planetary nature of objects in systems with multiple transiting exoplanet candidates. This method involves a FourierDomain analysis of the deviations in the transit times from a constant period that result from dynamical interactions within the system. The combination of observed anti-correlations in the transit times and mass constraints from dynamical stabil...
