A super-Earth transiting a nearby low-mass star
TLDR
Observations of the transiting planet GJ’1214b are reported, finding that the planetary mass and radius are consistent with a composition of primarily water enshrouded by a hydrogen–helium envelope that is only 0.05% of the mass of the planet.
The WASP project and the superWASP cameras
ABSTRACT The SuperWASP cameras are wide‐field imaging systems at the Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands, and at the Sutherland Station of the
A disintegrating minor planet transiting a white dwarf
TLDR
Observations of a white dwarf being transited by at least one, and probably several, disintegrating planetesimals are reported, providing further evidence that the pollution of white dwarfs by heavy elements might originate from disrupted rocky bodies such as asteroids and minor planets.
An orbital period of 0.94 days for the hot-Jupiter planet WASP-18b
TLDR
Either WASP-18 is in a rare, exceptionally short-lived state, or the tidal dissipation in this system (and possibly other hot-Jupiter systems) must be much weaker than in the Solar System.
THE FLAT TRANSMISSION SPECTRUM OF THE SUPER-EARTH GJ1214b FROM WIDE FIELD CAMERA 3 ON THE HUBBLE SPACE TELESCOPE
Capitalizing on the observational advantage oered by its tiny M dwarf host, we present HST/WFC3 grism measurements of the transmission spectrum of the super-Earth exoplanet GJ1214b. These are the rst
ON THE ANGULAR MOMENTUM EVOLUTION OF FULLY CONVECTIVE STARS: ROTATION PERIODS FOR FIELD M-DWARFS FROM THE MEarth TRANSIT SURVEY
We present rotation period measurements for 41 field M-dwarfs, all of which have masses inferred (from their parallaxes and Two Micron All Sky Survey K-band magnitudes) to be between the hydrogen
OBSERVATIONAL EVIDENCE FOR A METAL-RICH ATMOSPHERE ON THE SUPER-EARTH GJ1214b
We report observations of two consecutive transits of the warm super-Earth exoplanet GJ 1214b at 3.6 and 4.5 ?m with the Infrared Array Camera instrument on board the Spitzer Space Telescope. The two
A Faint New Milky Way Satellite in Bootes
We announce the discovery of a new satellite of the Milky Way in the constellation of Bootes at a distance of ~60 kpc. It was found in a systematic search for stellar overdensities in the north
WASP-1b and WASP-2b: Two new transiting exoplanets detected with SuperWASP and SOPHIE
TLDR
Using the newly commissioned radial-velocity spectrograph SOPHIE at the Observatoire de Haute-Provence, it is found that WasP-1b and WASP-2b exhibit reflex orbital radial-VELocity variations with amplitudes characteristic of planetary-mass companions and in-phase with the photometric orbits.
The GJ1214 Super-Earth System: Stellar Variability, New Transits, and a Search for Additional Planets
The super-Earth GJ1214b transits a nearby M dwarf that exhibits a 1% intrinsic variability in the near-infrared. Here, we analyze new observations to refine the physical properties of both the star
