Accretion of AGN Stars under Influence of Disk Geometry II: The Adiabatic Regime and Runaway Collapse Induced by Self-gravity
Yi-Xian Chen, Yan-Fei Jiang, Jeremy Goodman
Accretion onto massive stars embedded in Active Galactic Nuclei (AGN) disks around supermassive black holes (SMBHs) is regulated to the stellar Eddington rate in the fast-diffusion…
Spectral Appearance of Self-gravitating Disks Powered by Stellar Objects: Universal Effective Temperature in the Optical Continuum and Application to Little Red Dots
Yi-Xian Chen, Hanpu Liu, Ruancun Li +6
We revisit the spectral appearance of extended self-gravitating accretion disks surrounding compact central objects such as supermassive black holes. Using dust-poor opacities, we…
On the Missing Red Giants near the Galactic Center
Taeho Kim, Jeremy Goodman
There is a long-acknowledged deficiency of bright red giants relative to fainter old stars within a few arc seconds of Sgr A*. We explore whether this could be due to tidal strippi…
Accretion of AGN Stars under Influence of Disk Geometry
Yi-Xian Chen, Yan-Fei Jiang, Jeremy Goodman
Massive stars can form within or be captured by AGN disks, influencing both the thermal structure and metallicity of the disk environment. In a previous work, we investigated isotr…
Radiation Hydrodynamic Simulations of Massive Stars in Gas-rich Environments: Accretion of AGN Stars Suppressed By Thermal Feedback
Yi-Xian Chen, Yan-Fei Jiang, Jeremy Goodman +1
Massive stars may form in or be captured into AGN disks. Recent 1D studies employing stellar-evolution codes have demonstrated the potential for rapid growth of such stars through…
Stability of metal-rich very massive stars
J. Goodman, Christopher J. White
We revisit the stability of very massive nonrotating main-sequence stars at solar metallicity, with the goal of understanding whether radial pulsations set a physical upper limit t…
