Imaging planets around nearby white dwarfs
We suggest that Jovian planets will survive the late stages of stellar evolution, and that white dwarfs will retain planetary systems in wide orbits (∼ 5 AU). Utilising evolutionary models for Jovian planets, we show that infra-red imaging with 8m class telescopes of suitable nearby white dwarfs should allow us to resolve and detect companions ∼ 3MJUP. Detection of massive planetary companions ...
متن کاملBayesian search for low-mass planets around nearby M dwarfs – Estimates for occurrence rate based on global detectability statistics
Due to their higher planet-star mass-ratios, M dwarfs are the easiest targets for detection of low-mass planets orbiting nearby stars using Doppler spectroscopy. Furthermore, because of their low masses and luminosities, Doppler measurements enable the detection of low-mass planets in their habitable zones that correspond to closer orbits than for Solar-type stars. We re-analyse literature UVES...
متن کاملPlanets Around M-dwarfs – Astrometric Detection and Orbit Characterization
There are compelling reasons to search for planets around late M-dwarfs: current planet surveys have not been able to target these optically-faint stars, and the reduced primary stellar mass improves planet detection sensitivity for new techniques which can target these stars. In this white paper we argue that one can employ aging 2 m telescopes for dedicated astrometric programs in the spirit ...
متن کاملNew Debris Disks around Nearby Main-sequence Stars: Impact on the Direct Detection of Planets
Using the MIPS instrument on Spitzer, we have searched for infrared excesses around a sample of 82 stars, mostly F, G, andKmain-sequence field stars, alongwith a small number of nearbyM stars. These stars were selected for their suitability for future observations by a variety of planet-finding techniques. These observations provide information on the asteroidal and cometary material orbiting t...
متن کاملConstraints on Planet Occurrence Around Nearby Mid-to-Late M Dwarfs From the Mearth Project
The MEarth Project is a ground-based photometric survey intended to find planets transiting the closest and smallest main-sequence stars. In its first four years, MEarth discovered one transiting exoplanet, the 2.7R⊕ planet GJ1214b. Here, we answer an outstanding question: in light of the bounty of small planets transiting small stars uncovered by the Kepler mission, should MEarth have found mo...
