Eccentric Behavior of Eccentric Planets
Recent increases in the discovery of high multiplicity Sub-Jovian planetary systems, in addition to discoveries of giant planets of high eccentricities in these multiple body systems, lead to questions into their origins and evolution. The study of secular interactions is not new, however it has only recently been applied to exoplanetary systems. These systems sometimes fall far from the classi...
متن کاملTwo New Candidate Planets in Eccentric Orbits1
Doppler measurements of two G-type main-sequence stars, HD 210277 and HD 168443, reveal Keplerian variations that imply the presence of companions with masses (M sin i) of 1.28 and 5.04 M J (where is the mass of Jupiter) and orbital periods of 437 and 58 days, respectively. The orbits have M J large eccentricities of e\ 0.45 and e\ 0.54, respectively. All nine known extrasolar planet candidates...
متن کاملEccentric giant planets in open star clusters
The discovery of Jupiter–like planets with high eccentricities raises the question of how these eccentricities are produced. We propose that eccentric giant planets (EGPs) could be formed in open star clusters as a result of purely dynami-cal processes. It is found that at least 3% of the giant planets around stars in open clusters can develop high eccentricities due to multi-body gravitational...
متن کاملTransiting planets - lightcurve analysis for eccentric orbits
Transiting planet lightcurves have historically been used predominantly for measuring the depth and hence ratio of the planet-star radii, p. Equations have previously been presented by Seager & Mallén-Ornelas (2003) for the analysis of the total and trough transit lightcurve times to derive the ratio of semi-major axis to stellar radius, a/R∗, in the case of circular orbits. Here, a new analyti...
متن کاملTwo New Candidate Planets in Eccentric Orbits
Doppler measurements of two G–type main–sequence stars, HD210277 and HD168443, reveal Keplerian variations that imply the presence of companions with masses (M sin i ) of 1.28 and 5.04 MJUP and orbital periods of 437 d and 58 d, respectively. The orbits have large eccentricities of e=0.45 and e=0.54, respectively. All 9 known extrasolar planet candidates with a=0.2–2.5 AU have orbital eccentric...
