A Transiting Planet of a Sun-like Star
A planet transits an 11 magnitude, G1V star in the constellation Corona Borealis. We designate the planet XO-1b, and the star, XO-1, also known as GSC 02041-01657. XO-1 lacks a trigonometric distance; we estimate it to be 200±20 pc. Of the ten stars currently known to host extrasolar transiting planets, the star XO-1 is the most similar to the Sun in its physical characteristics: its radius is ...
متن کاملPhysical Parameters of the Parent Star and the Transiting Planet
The Sun-like star HD 209458 harbors a close-in giant planet which transits across the star’s disk, and thus allows an unprecedented access to the basic parameters of the planet, given a certain knowledge of the basic parameters of the star, namely its mass and radius. We present theoretical stellar evolution model calculations for HD 209458 and discuss the uncertainties involved in deriving the...
متن کاملtransiting extrasolar giant planet around the star OGLE - TR - 10
We report a transiting extrasolar giant planet around the star OGLE-TR-10 (orbital period = 3.1 days), which was uncovered as a candidate by the OGLE team in their photometric survey towards the Galactic center (Udalski et al. 2002a). We observed OGLE-TR-10 spectroscopically over a period of two years (2002–2004) using the HIRES instrument with an iodine cell on the Keck I telescope, and measur...
متن کاملSALT observations of the Chromospheric Activity of Transiting Planet Hosts: Mass Loss and Star Planet Interactions
We measured the chromospheric activity of the four hot Jupiter hosts WASP-43, WASP-51/HAT-P-30, WASP-72 & WASP-103 to search for anomalous values caused by the close-in companions. The Mount Wilson Ca ii H&K S -index was calculated for each star using observations taken with the Robert Stobie Spectrograph at the Southern African Large Telescope. The activity level of WASP-43 is anomalously high...
متن کاملHD 147506b: A SUPER-MASSIVE PLANET IN AN ECCENTRIC ORBIT TRANSITING A BRIGHT STAR
We report the discovery of a massive (Mp = 9.04±0.50MJup) planet transiting the bright (V = 8.7) F8 star HD 147506, with an orbital period of 5.63341±0.00013 days and an eccentricity of e = 0.520± 0.010. From the transit light curve we determine that the radius of the planet is Rp = 0.982± 0.105RJup. HD 147506b (also coined HAT-P-2b) has a mass about 9 times the average mass of previously-known...
