A PRECISE WATER ABUNDANCE MEASUREMENT FOR THE HOT JUPITER WASP-43b
The water abundance in a planetary atmosphere provides a key constraint on the planet’s primordial origins because water ice is expected to play an important role in the core accretion model of planet formation. However, the water content of the solar system giant planets is not well known because water is sequestered in clouds deep in their atmospheres. By contrast, short-period exoplanets hav...
متن کاملFrom Dense Hot Jupiter to Low Density Neptune: The Discovery of WASP-127b, WASP-136b and WASP-138b
We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18MJ and radius 1.35RJ. This is one of the least massive planets discovered by the WASP project. It orbits a bright host star (Vmag = 10.16) of spectral type G5 with a period of 4.17 days. WASP-127b is a low density planet which has an extended atmosphere with a scale h...
متن کاملSearching for Exoplanets in the Hertzsprung Gap: An Eccentric Hot Jupiter Orbiting the Subgiant HD185269
We report the detection of a Jupiter–mass planet in a 6.838 d orbit around the 1.28 M⊙ subgiant HD185269. The eccentricity of HD185269b (e = 0.30) is unusually large compared to other planets within 0.1 AU of their stars. Photometric observations demonstrate that the star is constant to ±0.0001 mag on the radial velocity period, strengthening our interpretation of a planetary companion. This pl...
متن کاملGround - Based Transit Spectroscopy of the Hot - Jupiter Wasp - 19 B in the near - Infrared
We present ground-based measurements of the transmission and emission spectra of the hot-Jupiter WASP-19b in nine spectroscopic channels from 1.25 to 2.35μm. The measurements are based on the combined analysis of time-series spectroscopy obtained during two complete transits and two complete secondary eclipses of the planet. The observations were performed with the MMIRS instrument on the Magel...
متن کاملKs-band secondary eclipses of WASP-19b and WASP-43b with the Anglo-Australian Telescope
We report new Ks-band secondary eclipse observations for the hot-Jupiters WASP-19b and WASP-43b. Using the IRIS2 infrared camera on the Anglo-Australian Telescope (AAT), we measured significant secondary eclipses for both planets, with depths of 0.287+0.020 −0.020 per cent and 0.181+0.027 −0.027 per cent for WASP-19b and WASP-43b, respectively. We compare the observations to atmosphere models f...
