WISE 1049AB Archives - Astrobiology

Simulated Doppler maps for WISE 1049A with injected spot models. On the night of Feb 11, a single polar spot model reproduces the observed map, while on Feb 9, a model with two polar spots is needed to reproduce the observed map. -- astro-ph.EP

Global Weather Map Reveals Persistent Top-of-atmosphere Features On The Nearest Brown Dwarfs

by Keith CowingAugust 20, 2024August 20, 2024

Brown dwarfs and planetary-mass companions display rotationally modulated photometric variability, especially those near the L/T transition. This variability is commonly attributed to top-of-atmosphere (TOA) inhomogeneities, with proposed models including patchy […]

Artist’s concept of stormy weather on a brown dwarf, such as those in the WISE 1049AB binary pair. NASA’s Webb space telescope has taken a detailed look at scorching storms on the 2 brown dwarfs.
