Planets around cool stars: a spectroscopic and photometric study of M dwarfs and their planets
M dwarfs have become attractive targets for exoplanet searches. Smaller planets can be detected around stars with smaller radii (via the transit technique) or lower mass (via the radial velocity technique). Planets in the habitable zone of an M dwarf are closer in, and thus easier to detect, than …

The properties of transiting exoplanets
… transit events. From a transit search of K2 M-dwarfs, I compiled a list of so-called “monster” planet candidates – Jupiter-sized planets orbiting M-dwarfs. I plan obtain high-resolution spectra of these targets in order to measure changes in the stellar radial velocity to infer masses of the …

Activity and kinematics of low mass stars
… and kinematics of approximately 70000 M dwarfs from the Sloan digital Sky Survey (SDSS) Data Release 7. This new analysis explores the spatial distribution of these M dwarf properties as a function of vertical distance from the Galactic plane (Z) and distance from the Galactic center (R). …

Modelling biogeochemical controls on planetary habitability
… 80 Gyr in the case of planets in the orbit of M-dwarfs. Contemporary measures of habitability that rely strongly on surface temperatures are becoming obsolete, and a move towards the inclusion of integrated biogeochemical cycle models and the development of multiparameter habitability indices …
