A recent paper by reserachers at Arizona State University shows the discovery of the coldest variable brown dwarf published to-date. The astronomers used the SWIRC instrument to monitor four brown dwarfs over multiple epochs. One of those showed significant variability. These ultracool dwarfs are important evolutionary links between giant planets and the lowest mass stars, and their atmospheres will continue to be investigated further with larger surveys.
