Eccentric Orbits of Close Companions to Asymptotic Giant Branch Stars
I propose that the relatively high eccentricity 0.1 ∼< e ∼< 0.4 found in some tidally strongly interacting binary systems, where the mass-losing star is an evolved giant star, e.g., an asymptotic giant branch star, is caused by an enhanced mass loss rate during periastron passages. Tidal interaction by itself will circularize the orbits of these systems in a relatively short time, hence a mecha...
متن کاملSingle Close Encounters Do Not Make Eccentric Planetary Orbits
The recent discovery of a planet in an orbit with eccentricity e = 0.63± 0.08 around the Solar-type star 16 Cyg B, together with earlier discoveries of other planets in orbits of significant eccentricity, raises the question of the origin of these orbits, so unlike the nearly circular orbits of our Solar system. In this paper I consider close encounters between two planets, each initially in a ...
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...
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 کاملThe Pan‐Pacific Planet Search: A Southern Hemisphere Search for Planets Orbiting Evolved Massive Stars
The vast majority of known extrasolar planets orbit stars with a narrow range of masses (0.7–1.3 M⊙). Little is known about the properties of planetary systems with host stars significantly more massive than the Sun. Planet formation models predict that giant planets are more common around higher-mass stars (M∗ > 1.5M⊙). However, these types of stars pose severe observational challenges while o...
