The habitability of planets orbiting M-dwarf stars

Physics Reports, 2016
The prospects for the habitability of M-dwarf planets have long been debated, due to key differences between the unique stellar and planetary environments around these low-mass stars, as compared to hotter, more luminous Sun-like stars. Over the past decade, significant progress has been made by both space- and ground-based observatories to measure the

Radial velocities of M dwarf stars

Publications of the Astronomical Society of the Pacific, 1987
Radial velocities for 72 M dwarfs have been obtained having internal errors of about 0.1 km/s and external errors of about 0.4 km/s. Multiple velocity measurements of ten dMe stars have yielded a set of six which have no stellar companions, providing confirmation that the dMe phenomenon can occur in single stars.

Coronal Structure in M Dwarf Stars

1996
In view of the importance of these objects as observational probes for theories of stellar dynamos and coronal heating, as well as their potentially important role in the galactic environment, we implemented a program of pointed ROSAT PSPC observations of selected M dwarfs in the solar neighborhood.
