Dino Chih-Chun Hsu @chihchunhsu.bsky.social · 27/03/2026Check out this great work by @maddielam.bsky.social and @johannavos.bsky.social for a deep dive in silicate cloud absorption and inclinations! From L dwarfs in AB Dor, we find an interesting trend that lower inclination correlate with the stronger silicate cloud absorption! 171
Dino Chih-Chun Hsu @chihchunhsu.bsky.social · 16/02/2026I am super excited to share our new paper on the spin of brown dwarfs and giant planets, accepted to AJ earlier this month. With the large spin survey, we found the first clear evidence that the spins of giant planets and brown dwarf companions (>5 au) are distinct. arxiv.org/abs/2601.05976 1160
