A super-Earth transiting a nearby low-mass star
- D. Charbonneau, Z. K. Berta, +16 authors T. Forveille
- Physics, Medicine
- Nature
- 16 December 2009
A decade ago, the detection of the first transiting extrasolar planet provided a direct constraint on its composition and opened the door to spectroscopic investigations of extrasolar planetary… Expand
THE FLAT TRANSMISSION SPECTRUM OF THE SUPER-EARTH GJ1214b FROM WIDE FIELD CAMERA 3 ON THE HUBBLE SPACE TELESCOPE
- Z. K. Berta, D. Charbonneau, +7 authors D. Homeier
- Physics
- 23 November 2011
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… Expand
ON THE ANGULAR MOMENTUM EVOLUTION OF FULLY CONVECTIVE STARS: ROTATION PERIODS FOR FIELD M-DWARFS FROM THE MEarth TRANSIT SURVEY
- J. Irwin, Z. K. Berta, +4 authors E. Falco
- Physics
- 22 November 2010
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… Expand
OBSERVATIONAL EVIDENCE FOR A METAL-RICH ATMOSPHERE ON THE SUPER-EARTH GJ1214b
- J. D'esert, J. Bean, +6 authors P. Nutzman
- Physics
- 11 March 2011
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… Expand
The Optical and Near-infrared Transmission Spectrum of the Super-Earth GJ?1214b: Further Evidence for a Metal-rich Atmosphere
- J. Bean, J. D'esert, +7 authors A. Seifahrt
- Physics
- 3 September 2011
We present an investigation of the transmission spectrum of the 6.5 M ? planet GJ?1214b based on new ground-based observations of transits of the planet in the optical and near-infrared, and on… Expand
The GJ1214 Super-Earth System: Stellar Variability, New Transits, and a Search for Additional Planets
- Z. K. Berta, D. Charbonneau, +5 authors E. Falco
- Physics
- 2 December 2010
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… Expand
The Transit Light Curve Project. XIII. Sixteen Transits of the Super-Earth GJ 1214b
- J. A. Carter, J. Winn, +4 authors P. Nutzman
- Physics
- 2 December 2010
We present optical photometry of 16 transits of the super-Earth GJ 1214b, allowing us to refine the system parameters and search for additional planets via transit timing. Starspot-crossing events… Expand
Transit Detection in the MEarth Survey of Nearby M Dwarfs: Bridging the Clean-first, Search-later Divide
- Z. K. Berta, J. Irwin, D. Charbonneau, C. Burke, E. Falco
- Physics
- 20 June 2012
In the effort to characterize the masses, radii, and atmospheres of potentially habitable exoplanets, there is an urgent need to find examples of such planets transiting nearby M dwarfs. The MEarth… Expand
LSPM J1112+7626: DETECTION OF A 41 DAY M-DWARF ECLIPSING BINARY FROM THE MEARTH TRANSIT SURVEY
We report the detection of eclipses in LSPM J1112+7626, which we find to be a moderately bright (I{sub C} = 12.14 {+-} 0.05) very low mass binary system with an orbital period of 41.03236 {+-}… Expand
GJ 3236: A New Bright, Very Low Mass Eclipsing Binary System Discovered by the MEARTH Observatory
- J. Irwin, D. Charbonneau, +14 authors D. Starr
- Physics
- 23 June 2009
We report the detection of eclipses in GJ 3236, a bright (I = 11.6), very low mass binary system with an orbital period of 0.77 days. Analysis of light and radial velocity curves of the system… Expand
