Measurement of Spin-orbit Misalignment and Nodal Precession for the Planet around Pre-main-sequence Star Ptfo 8-8695 from Gravity Darkening
PTFO 8-8695b represents the first transiting exoplanet candidate orbiting a pre-main-sequence star (van Eyken et al. 2012). We find that the unusual lightcurve shapes of PTFO 8-8695 can be explained by transits of a planet across an oblate, gravity-darkened stellar disk. We develop a theoretical framework for understanding precession of a planetary orbit’s ascending node for the case when the s...
متن کاملStarspots and spin - orbit alignment for Kepler cool host stars
The angle between the spin axis of the host star and the orbit of its planets (i.e., the stellar obliquity) is precious information about the formation and evolution of exoplanetary systems. Measurements of the Rossiter-McLaughlin effect revealed that many stars that host a hot-Jupiter have high obliquities, suggesting that hot-Jupiter formation involves excitation of orbital inclinations. In t...
متن کاملSpin-Orbit Coupling Induced Surface Band Splitting in LiyW(110) and LiyMo(110)
The broken symmetry at surfaces can give rise to a nonzero spin-orbit splitting of valence bands. We observe such a splitting of the d-derived surface state on W(110) and, to a lesser extent, on Mo(110), and follow the evolution of the splitting as monovalent atoms are adsorbed. The observed evolution is directly relevant to recent observations of altered orbital magnetic structure versus adsor...
متن کاملSpin-orbit alignment in the very low mass binary regime
Studies of solar-type binaries have found coplanarity between the equatorial and orbital planes of systems with <40 AU separation. By comparison, the alignment of the equatorial and orbital axes in the substellar regime, and the associated implications for formation theory, are relatively poorly constrained. Here we present the discovery of the rotation period of 3.32 ± 0.15 h from 2MASS J0746+...
متن کاملMeasurement of Spin-orbit Alignment in an Extrasolar Planetary System
We determine the stellar, planetary, and orbital properties of the transiting planetary systemHD 209458 through a joint analysis of high-precision radial velocities, photometry, and timing of the secondary eclipse. Of primary interest is the strong detection of the Rossiter-McLaughlin effect, the alteration of photospheric line profiles that occurs because the planet occults part of the rotatin...
