Most LRDs fit case B recombination, with one major exception
—
in AstronomyWhat the study found Most Little Red Dots (LRDs), compact extragalactic objects with a v-shaped optical spectrum and broad lines, are broadly consistent with case B recombination, a standard model for hydrogen emission in ionized gas. One object, RUBIES-EGS-4233_49140 at redshift 6.68, shows a strong and unusual deviation. Why the authors say this matters The…
DM Tau disk shows non-thermal line broadening
—
in AstrophysicsBayesian analysis of molecular line observations confirms nonthermal broadening of 0.4 sound speeds in the DM Tau protoplanetary disk, providing evidence for turbulence.
Tomographic line analysis identifies possible embedded planets in disks
—
in AstrophysicsTomographic analysis of molecular line observations enables detection of embedded planets in protoplanetary disks, revealing multiple planet candidates in HD 135344B and MWC 758.
