The ” missing link ” : a 4 - day period transiting exoplanet around OGLE - TR - 111 ⋆
We report the discovery of a transiting hot Jupiter around OGLE-TR-111, from our radial velocity follow-up of OGLE transiting candidates in Carina. The planet has a mass of 0.53 ± 0.11 M J and a radius of 1.0 +0.13 −0.06 R J. Three transiting exoplanets have already been found among OGLE candidates, all with periods near 1.5 days. The planet presented here, with P = 4.0 days, is the first exopl...
متن کاملKepler-16: a transiting circumbinary planet.
We report the detection of a planet whose orbit surrounds a pair of low-mass stars. Data from the Kepler spacecraft reveal transits of the planet across both stars, in addition to the mutual eclipses of the stars, giving precise constraints on the absolute dimensions of all three bodies. The planet is comparable to Saturn in mass and size and is on a nearly circular 229-day orbit around its two...
متن کاملA Planet with a 3.1 Day Period around a Solar Twin
Doppler measurements from the Keck/HIRES spectrometer of the G3 V star HD 187123 reveal Keplerian variations with a period of 3.097 days and a semiamplitude of 72 m s. An orbital fit yields a companion mass of , a semimajor axis of AU, and an eccentricity of M 5 0.52 M / sin i a 5 0.042 e 5 0.03 JUP (consistent with zero). HD 187123 appears similar to the Sun in mass, age, chromosphere, and rot...
متن کاملA 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 کاملToward a homogeneous set of transiting planet parameters
With 40 or more transiting exoplanets now known, the time is ripe to seek patterns and correlations among their observed properties, which may give important insights into planet formation, structure, and evolution. This task is made difficult by the widely different methodologies that have been applied to measure their properties in individual cases. Furthermore, in many systems our knowledge ...
