Can super-Earths' interior dynamics set the table for habitability?（图）
super-Earths interior dynamics set habitability
2021/3/5
New research led by Yingwei Fei of the Carnegie Institution for Science provides a framework for understanding the interiors of super-Earths -- rocky exoplanets between 1.5 and 2 times the s...
If you have a coin and flip it just once, what does that tell you about the odds of heads versus tails? asks Heather Knutson, assistant professor of planetary science at Caltech. "It tells you almost ...
On the Detection of (Habitable) Super-Earths Around Low-Mass Stars Using Kepler and Transit Timing Variation Method
Planetary Systems
2011/10/9
We present the results of an extensive study of the detectability of Earth-sized planets and super-Earths in the habitable zones of cool and low-mass stars using transit timing variation method. We ha...
Thermal evolution and lifetime of intrinsic magnetic fields of Super Earths in habitable zones
Thermal evolution intrinsic magnetic fields
2011/1/11
We have numerically studied the thermal evolution of various-mass terrestrial planets in habitable zones, focusing on duration of dynamo activity to generate their intrinsic magnetic fields, which may...
On planetary mass determination in the case of super-Earths orbiting active stars. The case of the CoRoT-7 system
CoRoT-7b CoRoT-7c mass determination exoplanets super-Earths
2010/11/12
Context. Due to the great contribution of the star activity in the measured radial velocities, the masses of CoRoT-7b and CoRoT 7c are very uncertain. Therefore, we are dealing with the typical proble...
The Occurrence and Mass Distribution of Close-in Super-Earths, Neptunes, and Jupiters
Close-in Super-Earths Neptunes Jupiters

The Occurrence and Mass Distribution of Close-in Super-Earths, Neptunes, and Jupiters.
A Population of Very-Hot Super-Earths in Multiple-Planet Systems Should be Uncovered by Kepler
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
We simulate a Kepler-like observation of a theoretical exoplanet population and we show that the observed orbital period distribution of the Kepler giant planet candidates is best matched by an averag...
