PublicationConstraints to the masses of brown dwarf candidates form the lithium test
We present intermediate dispersion (0.7-2.2 A/pixel) optical spectroscopic observations aimed at applying the 'lithium test' to a sample of 10 brown dwarf...
NewsMARK MARLEY: “One great challenge when studying planetary atmospheres is clouds, which both brown dwarfs and extrasolar planets have”
Our planet becomes too small for some scientists, therefore they dedicate their lives to study other worlds much larger than Earth and those that are so massive...
