The Stellar Planet Survey (STEPS) is an ongoing astrometric search for giant planets and brown dwarfs around a sample of ~30 M-dwarfs. We have discovered several low-mass companions by measuring the motion of our target stars relative to their reference frames. We describe the STEPS method for stellar centroiding that enables our ~1 milliarcsecond relative astrometry. We describe one of the astrometrically discovered companions, GJ 1210B, which was later confirmed with an imaging observation… Expand
The PRIMA astrometric planet search: goals and prospects
ESO's PRIMA (Phase-Referenced Imaging and Micro-arcsecond Astrometry) facility at the VLT Interferometer on Cerro Paranal in Chile is expected to be fully operational in only a couple of years fromExpand
M stars as targets for terrestrial exoplanet searches and biosignature detection.
It is concluded that attempts at remote sensing of biosignatures and nonbiological markers from M star planets are important, not as tests of any quantitative theories or rational arguments, but instead because they offer an inspection of the residues from a Gyr-long biochemistry experiment in the presence of extreme environmental fluctuations.

Biosignatures from Earth-like planets around M dwarfs.
Coupled one-dimensional photochemical-climate calculations have been performed for hypothetical Earth-like planets around M dwarfs to determine which biosignature gases might be observed by a future, space-based telescope. Expand
