on TRAPPIST-1

TRAPPIST-1 (also known as 2MASS J23062928-0502285, which handily contains its location on the sky) is about 12 parsecs away, or 39.5 light years. That means it’s one of the closest 500 stars to the Sun, and we now know… 691 more words

Parallaxes and proper motions of 134 southern late M, L and T dwarfs

Stars in nearby solar space exhibit large proper motions because they are moving against a background of more distant stars. All stars have their own motion through space and most stars in the solar vicinity share approximately the velocity and direction of motion of the Sun. 288 more words

New nearby high proper motion objects from the AllWISE survey

Many years of work have gone into the quest to find the nearest objects outside the Solar System. The holy grail of a proper motion search based on (thermal) infrared data where low mass stars and brown dwarfs emit most of their radiation and where extinction by dust in the galactic plane is low has been achieved by the latest… 402 more words
