If Uranus’s oscillations are comparable to Saturn’s, a low-flying orbiter could detect modes with low angular degree after only a few close passes, while higher-degree modes would require at least eight passes.

A deep search for high-redshift galaxies in some of the richest JWST imaging to date emphasizes the importance of medium-band filters in excluding low-redshift interlopers and maximizing completeness.

In simulations featuring an inner disk tilted by 30 degrees, the outer disk develops a thermally driven warp due to launching of bending waves, which drives a tilting response in the outer disk.

Two newly discovered brown dwarfs occupy an underpopulated region of the brown dwarf mass–period parameter space; one brown dwarf appears to be under luminous, which is rare among brown dwarfs.

New modeling shows that super-Eddington accretion can account for the lack of observed variability in little red dots; if their accretion is sub-Eddington, photometric variability should have been detected by now.

Of the 68 brown dwarfs identified in a recent study, 12 are newly discovered and two are more than 5 kiloparsecs away, making them the most distant known brown dwarfs in our galaxy.
