The NASA-UC Eta-Earth Program: III. A Super-Earth orbiting HD 97658 and a Neptune-mass planet orbiting Gl 785
planetary systems stars individual techniques radial velocity
2010/11/9
We report the discovery of planets orbiting two bright, nearby early K dwarf stars, HD97658 and
Gl 785. These planets were detected by Keplerian modelling of radial velocities measured with Keck-HIRE...

2010/12/23
Solar coronal mass ejections (CMEs) are the most significant drivers of adverse space weather at Earth, but the physics governing their propagation through the heliosphere is not well understood. Whil...
Thermal evolution and interior models of the transiting super-Earth GJ 1214b
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/23
The planet GJ 1214b is the second known super-Earth with a measured mass and radius. Orbiting a quiet M-star, it receives considerably less mass-loss driving X-ray and UV radiation than CoRoT-7b, so t...
