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

The Brown Dwarf Desert

A brown dwarf is an object that’s too massive to be a planet, but not massive enough to fuse hydrogen and be considered a star like our Sun. 690 more words
