Backyard Worlds: Planet 9 is a NASA-funded citizen science project which is part of the Zooniverse web portal. [1 ] It aims to discover new brown dwarfs, faint objects that are less massive than stars, some of which might be among the…
The temperature was estimated to be lower than 381 Kelvin for this object. [4 ] Follow-up observations however revised the color to ch1-ch2 = 2.986 ±0.048 mag, making it the fifth reddest object at the time, with an estimated temperature of…
They have temperatures below around 500 Kelvin (227°C; 440°F) and are colder than T-dwarfs. [1 ] [2 ] Y-dwarfs have a similar spectrum when compared to the giant planet Jupiter. [3 ]
An object with the spectral type T (also called T dwarf or methane brown dwarf) [1 ] is either a brown dwarf [2 ] or a young free-floating planetary-mass object. [3 ] A directly imaged exoplanet with a young age can also be a T-dwarf. [4…
