Exotic Earths: forming habitable worlds with giant planet migration.
Close-in giant planets (e.g., "hot Jupiters") are thought to form far from their host stars and migrate inward, through the terrestrial planet zone, via torques with a massive gaseous disk. Here we simulate terrestrial planet growth during and after giant planet migration. Several-Earth-mass planets also form interior to the migrating jovian planet, analogous to recently discovered "hot Earths....
متن کاملDetecting biomarkers in habitable-zone earths transiting white dwarfs
The characterization of the atmospheres of habitable-zone Earth-mass exoplanets that transit across main-sequence stars, let alone the detection of biomarkers in their atmospheres, will be challenging even with future facilities. It has been noted that white dwarfs (WDs) have long-lived habitable zones and that a large fraction of WDs may host planets. We point out that during a transit of an E...
متن کاملA dynamically-packed planetary system around GJ 667C with three super-Earths in its habitable zone ⋆⋆⋆⋆⋆⋆
Context. Since low-mass stars have low luminosities, orbits at which liquid water can exist on Earth-sized planets are relatively close-in, which produces Doppler signals that are detectable using state-of-the-art Doppler spectroscopy. Aims. GJ 667C is already known to be orbited by two super-Earth candidates. We have applied recently developed data analysis methods to investigate whether the d...
متن کاملFinding habitable earths around white dwarfs with a robotic telescope transit survey
I discuss the possibility that white dwarfs might harbor habitable planets at 0.01 AU that arrive there after the red giant phase. These planets would be detectable with ground-based telescopes via deep transits of the star, and a transit survey of the nearest white dwarfs would favor detection of Earth-temperature planets, assuming they could form as close as twice the Roche limit. I show that...
