What makes a planet habitable
Helmut Lammer,Jan Hendrik Bredehöft,Athena Coustenis,Maxim L. Khodachenko,Lisa Kaltenegger,Olivier Grasset,Daniel Prieur,François Raulin,Pascale Ehrenfreund,M. Yamauchi,Jan-Erik Wahlund,Jean-Mathias Grießmeier,Günter Stangl,Charles S. Cockell,Yu. N. Kulikov,John Lee Grenfell,Heike Rauer +16 more
TL;DR: In this article, the authors discuss the geodynamical and geophysical environments which are necessary for planets where plate tectonics remain active over geological time scales and for planets which evolve to one-plate planets.
Journal ArticleDOI
Coronal mass ejection (CME) activity of low mass M stars as an important factor for the habitability of terrestrial exoplanets. I. CME impact on expected magnetospheres of Earth-like exoplanets in close-in habitable zones.

TL;DR: It is shown that Earth-like exoplanets within close-in HZs should experience a continuous CME exposure over long periods of time, which may result in little or no magnetospheric protection of planetary atmospheres from a dense flow of CME plasma.
Journal ArticleDOI
Searching for star–planet interactions within the magnetosphere of HD 189733

TL;DR: In this paper, the magnetic field and activity of the host star were studied using the ESPaDOnS and the NARVAL spectropolarimeters, installed at the 3.6m Canada-France-Hawaii telescope and the 2m Telescope Bernard Lyot at Pic du Midi, during two monitoring campaigns (2007 June and 2008 July).
Journal ArticleDOI
The extreme physical properties of the CoRoT-7b super-Earth

Schuller,Franck Selsis,Christophe Sotin +25 more
TL;DR: In this article, the authors make the working hypothesis that CoRoT-7b is a rocky super-Earth with no volatiles in its atmosphere, and derive the physical properties that result.
Journal ArticleDOI

TL;DR: Through simultaneous observations, synchronous switching in the radio and x-ray emission properties of pulsar PSR B0943+10 is detected, indicating rapid, global changes to the conditions in the magnetosphere, which challenge all proposed pulsar emission theories.
