Researchers have applied a new Python-based spectral fitting tool to JWST spectra of the young protostar NGC 1333 IRAS 2A, identifying previously noted and new ice species and complex organic molecules.
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.
