A Framework to Model Stellar Irradiated Disks with Frequency-dependent Absorption and Scattering Opacities in Athena++
Stanley A. Baronett, Yan-Fei Jiang, Zhaohuan Zhu +2
The frequency dependence of opacity is crucial for determining the thermal structure of protoplanetary disks, which in turn influences disk dynamics and planet formation. Yet many…

Does magnetic field promote or suppress fragmentation in AGN disks? Results from local shearing box simulations with simple cooling
Tsun Hin Navin Tsung, Mitchell C. Begelman, Philip J. Armitage +2
Accretion disks in Active Galactic Nuclei (AGN) are predicted to become gravitationally unstable substantially interior to the black hole's sphere of influence, at radii where the…

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…
