Get Instant Summarized Text (Gist) Two new brown dwarfs, TOI-4776 b and TOI-5422 b, have been discovered using TESS. TOI-4776 b is about 32 times the mass of Jupiter, orbits an F-type star every ...

This variability is attributed to several atmospheric ... Traditionally, astronomical classifications have separated stars, planets, and brown dwarfs, with planets typically being much smaller ...

However, "it also has a lower mass than a typical brown dwarf [a so-called 'failed star ... which could have caused some of the variability in the wavelength clusters' curves.

"The goal of this project was to explore the fundamental low-mass limit of the star and brown dwarf formation process." The James Webb Space Telescope (JWST) has probed deep into the dusty shroud ...
