The Stability Analysis of the Exoplanetary Systems
To date, more than 100 giant Jupiter-like planets have been discovered in Doppler surveys of solar-type stars. In this paper, we perform simulations to investigate three systems: GJ 876, HD 82943 and 55 Cnc. The former two systems both have a pair of planets in the 2:1 Mean Motion Resonance (MMR), while the inner two companions of the later is close to 3:1 MMR. By integrating hundreds of the pl...
متن کاملStarspots and Spin-orbit Alignment in the Wasp-4 Exoplanetary System
We present photometry of 4 transits of the exoplanet WASP-4b, each with a precision of approximately 500 ppm and a time sampling of 40-60 s. We have used the data to refine the estimates of the system parameters and ephemerides. During two of the transits we observed a short-lived, low-amplitude anomaly that we interpret as the occultation of a starspot by the planet. We also found evidence for...
متن کاملThe Occurrence and Architecture of Exoplanetary Systems
The basic geometry of the Solar System—the shapes, spacings, and orientations of the planetary orbits—has long been a subject of fascination as well as inspiration for planet-formation theories. For exoplanetary systems, those same properties have only recently come into focus. Here we review our current knowledge of the occurrence of planets around other stars, their orbital distances and ecce...
متن کاملStarspots, Spin-orbit Misalignment, and Active Latitudes in the Hat-p-11 Exoplanetary System
We present the analysis of 4 months of Kepler photometry of the K4V star HAT-P-11, including 26 transits of its “super-Neptune” planet. The transit data exhibit numerous anomalies that we interpret as passages of the planet over dark starspots. These spot-crossing anomalies preferentially occur at two specific phases of the transit. These phases can be understood as the intersection points betw...
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...
