M Dwarf Stars In subject area: Physics and Astronomy M Dwarf Stars are low-mass stars that host closely-packed planetary systems, often with multiple rocky planets. They are known to have a paucity of Jupiter-mass planets and approximately one-third of these rocky planets orbit within the habi...

M-dwarfs, can support liquid water and eventually life. A new study shows that subglacial melting may provide an answer, significantly extending the habitability region, in particular around M-dwarf stars, which are also the most promising for biosignature detection with the present and...
M-dwarf stars are extremely common in the universe and a typical one is relatively small and dim, making it easy for astronomers to detect a passing planet. If orbiting planets huddle close enough to an M-dwarf, in theory they could fall within the habitable zone where surface liquid water...

M dwarf stars are currently the main targets in searches for potentially habitable planets. However, their winds have been suggested to be harmful to planetary atmospheres. Here, in order to better understand the winds of M dwarfs and also infer their physical properties, we perform a one-...
HD 142527A is one of the most studied Herbig Ae/Be stars with a transitional disk, as it has the largest imaged gap in any protoplanetary disk: the gas is cleared from 30 to 90 AU. The HD 142527 system is also unique in that it has a stellar companion with a small mass compared ...
The sort ofsmall, young, active starsthat have become most exciting to astronomers looking for exoplanets may actually push away precisely what could be necessary to carry water to those planets — leaving them too dry to support life.
