UrduDemasiado grandes para ser planetas, pero demasiado pequeñas para ser estrellas, las enanas café más distantes son un ingrediente clave para entender la historia de la Vía Láctea. Por tal motivo, la Investigación del Espacio-Tiempo como Legado para la posteridad del Observatorio Vera C. Rubin será clave para detectar una población de antiguas enanas café que se espera sea unas 20 veces mayor de lo que se ha visto hasta el momento, con lo que será posible revelar los procesos que dieron forma a nuestra galaxia.

NSF–DOE Rubin Observatory Will Detect Thousands of Elusive Brown Dwarfs, Unlocking Milky Way Mysteries
Too big to be planets but too small to be stars, distant brown dwarfs are a key ingredient for understanding the history of the Milky Way. Vera C. Rubin Observatory’s Legacy Survey of Space and Time will detect a population of ancient brown dwarfs about 20 times bigger than we’ve previously seen, revealing the processes that shaped our home galaxy.
NASA’s Hubble Finds that Aging Brown Dwarfs Grow Lonely
A Hubble telescope survey has found that brown dwarfs—objects smaller than stars but bigger than planets—live a lonely life as they age. Over time they lose the companion brown dwarf that was born alongside them and the objects drift their separate ways.
Astronomers Probe Layer-Cake Structure of Brown Dwarf’s Atmosphere
Researchers used the giant W. M. Keck Observatory in Hawaii to observe a nearby brown dwarf in infrared light. They found that the dwarf’s atmosphere has a layer-cake structure with clouds of different composition at different altitudes.
Astronomers Measure Wind Speed on a Brown Dwarf
Using VLA and Spitzer observations, astronomers are able to determine wind speeds on a brown dwarf for the first time. They believe the technique also could be used for exoplanets.
