Tidal Interactions and Disruptions of Giant Planets on Highly Eccentric Orbits
We calculate the evolution of planets undergoing a strong tidal encounter using smoothed particle hydrodynamics (SPH), for a range of periastron separations. We find that outside the Roche limit, the evolution of the planet is well-described by the standard model of linear, non-radial, adiabatic oscillations. If the planet passes within the Roche limit at periastron, however, mass can be stripp...
متن کاملOn the tidal interaction of massive extra-solar planets on highly eccentric orbit
In this paper we develop a theory of disturbances induced by the stellar tidal field in a fully convective slowly rotating planet orbiting on a highly eccentric orbit around a central star. In that case it is appropriate to treat the tidal influence as a succession of impulsive tidal interactions occurring at periastron passage. For a fully convective planet mainly the l = 2 fundamental mode of...
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...
متن کاملType Ii Migration of Planets on Eccentric Orbits
The observed extrasolar planets possess both large masses (with a median M sin i of 1.65 MJ) and a wide range in orbital eccentricity (0 < e < 0.94). As planets are thought to form in circumstellar disks, one important question in planet formation is determining whether, and to what degree, a gaseous disk affects an eccentric planet’s orbit. Recent studies have probed the interaction between a ...
