Ultracool dwarf stars are widespread in the solar neighborhood. Nevertheless, their extremely low brightness has left their planetary population largely...
Current theories predict that low-mass stars should rarely host planets with masses exceeding that of Neptune (17 Earth masses).

Astronomers using NASA’s Spitzer Space Telescope have identified three fastest-spinning ultracool dwarfs ever found: 2MASS J03480772-6022270, 2MASS J12195156+3128497,...
Astronomers using NSF’s Very Long Baseline Array, a continentwide system of 10 radio telescope antennas located between Hawaii and Puerto Rico, have...
Using data from NASA’s Kepler/K2 mission, the SPECULOOS telescopes and the High Resolution Echelle Spectrometer (HIRES) on the Keck I telescope at W.M....
Using data from the European Photon Imaging Camera (EPIC) onboard ESA’s XMM-Newton X-ray observatory, astronomers have detected for the first time a...
A team of astronomers from the United Kingdom and Germany has spotted a superflare coming from an L-dwarf star approximately 250 light-years away that’s...
Using a planet-hunting technique called gravitational microlensing, astronomers have detected an Earth-mass planet orbiting an ultracool dwarf 12,750 light-years...
A study led by British planetary scientists has provided evidence that auroras occur on a number of very low mass stars and brown dwarfs, collectively...
