00:31 <galois> [arXiv] “The impermanent fate of massive stars in AGN disks” Mohamad Ali-Dib, Douglas N. C. Lin — «Stars are likely to form or to be captured in AGN disks. Their mass reaches an equilibrium when their rate of accretion is balanced by that of wind. If the exchanged gas is well mixed with the stellar core, this metabolic process would indefinitely sustain an "immortal" state on the main sequence (MS) and pollute the disk with He…»
