GJ 1214 b, auch Gliese 1214 b, ist eine im Jahr 2009 entdeckte extrasolare Supererde.Bei seiner Entdeckung durch Zachory Berta war er der erdähnlichste bekannte Exoplanet. . Er ist knapp 40 Lichtjahre von der Erde entfernt und umkreist in 38 Stunden im Sternbild Schlangenträger den roten Zwerg GJ 1214, dessen Strahlung 200 Mal schwächer ist als diejenige der Son

The atmosphere of exoplanet GJ1214b around a red star of 40 light years away is reported to be confined with heavy clouds of not so transparent with H2O, CH4,N2 CO, CO2 and may be NH3. We can compare these large exoplanets with the atmosphere of our giants like Jupiter,Saturn, and Neptune.

2014 • 2014Natur.50569K All WISE Data Release The exoplanet GJ1214b presents an interesting example of compositional degeneracy for low-mass planets. Its atmosphere may be composed of water, super-solar or solar metallicity material. We present atmospheric circulation models of GJ1214b for these three compositions, with explicit gray radiative transfer and an optional treatment of MHD bottom drag. All models develop strong, superrotating Se hela listan på github.com Gliese 1214 b was discovered in data taken between June and August 2009. The discovery observations were made by the eight identical 40-cm telescopes that form the MEarth Project and follow up observations were taken with the F. L. Whipple Observatory (FLWO) 1.2-meter telescope. 2010-12-01 · The recently discovered transiting super-Earth exoplanet GJ 1214b is one example of this problem3.

grism measurements of the transmission spectrum of the super-Earth exoplanet GJ1214b. These are the rst published WFC3 observations of a transiting exoplanet atmosphere. After correcting for a ramp-like instrumental systematic, we achieve nearly photon-limited precision in these observations, nding the transmission spectrum of GJ1214b to be

Note: Document ID: 20110007792. and Nature; Volume 468; 636-637. 2015-10-29 The Hubble Telescope discovered evidence of high altitude clouds covering super-Earth exoplanet, GJ1214b. The super-Earth exoplanet is about 40 light years away and can be found towards the constellation Ophiuchus. Super-Earth planets have up to ten times the mass of the planet Earth and GJ1214b is bout 6.5 times the mass of Earth.

"When an exoplanet passes in front of its star, light can be absorbed at some wavelengths by molecules in Four CfA astronomers, Zachory Berta, David Charbonneau, Jean-Michel Desert, and Jonathan Irwin, together with six colleagues, used the Hubble Space Telescope to probe the atmosphere around the transiting super-Earth known as GJ1214b.

The planet, GJ1214b, has a mass about six times that of Earth and its interior is likely mostly made of water ice. World's most comprehensive interactive database of extrasolar planets updated daily since 1995. Detailed information on planet GJ 1214 b orbiting around star GJ 1214.

1 Dec 2010 The recently discovered transiting super-Earth GJ1214b is one example of this problem. Three distinct models for the planet that are consistent  21 Feb 2012 Observations of the extrasolar planet GJ1214b by NASA's Hubble Space Telescope have come up with a new class of planet, a waterworld  exoplanet GJ 1214b. Mon. Not. R. Astron. Soc. 431, 1669–1677 (2013).

“GJ1214b is quite close to Earth, just 42 light years away, and it orbits its star in just 1.6 days.” That fast orbit gave scientists the opportunity to record the exoplanet’s flat spectrum, ruling out an atmosphere of simple hydrogen, water, carbon dioxide or methane.
