UA Astronomers Track the Birth Super-Earth
2017/7/24
A new model giving rise to young planetary systems offers a fresh solution to a puzzle that has vexed astronomers ever since new detection technologies and planet-hunting missions such as NASA's ...
Habitability of Super-Earth Planets around Main-Sequence Stars including Red Giant Branch Evolution: Models based on the Integrated System Approach
Main-Sequence Stars including Red Giant Branch Evolution Models based Integrated System Approach
2011/10/20
In a previous study published in Astrobiology, we focused on the evolution of habitability of a 10 M_E super-Earth planet orbiting a star akin to the Sun. This study was based on a concept of planetar...
Occurrence of the 2:1 commensurability in a gas giant-Super-Earth system
methods: numerical - planets and satellites: formation
2011/10/19
We investigate how the conditions occurring in a protoplanetary disc may determine the final structure of a planetary system emerging from such a disc. We concentrate our attention on the dynamical in...
The 55 Cancri System: Fundamental Stellar Parameters, Habitable Zone Planet, and Super-Earth Diameter
Cancri System: Fundamental Stellar Parameters Super-Earth Diameter
2011/9/30
The bright star 55 Cancri is known to host five planets, including a transiting super-Earth. We use the CHARA Array to directly determine the following of 55 Cnc's stellar astrophysical parameters: $R...
Super-Earth's atmosphere comes into view（图）
Super-Earth's atmosphere astronomers the first extra-solar planet
2011/1/21
A team of astronomers has made the first direct measurement of the atmosphere of an exoplanetary "super-Earth". The findings suggest that the exoplanet named GJ 1214b has either an atmosphere swarming...
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...
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...
