Resolving Oblique Star-Disk Collisions in Quasi-Periodic Eruptions: Numerical Requirements and the Importance of Geometry
Shunquan Huang, Xiaoshan Huang, Zhaohuan Zhu +1
Star-disk collisions have been proposed as a promising mechanism for producing quasi-periodic eruptions (QPEs) in galactic nuclei. Because the stellar atmospheric scale height is o…

Radiation-magnetohydrodynamic Simulations of Accretion Flow Formation After a Tidal Disruption Event
Maria Renee Meza, Xiaoshan Huang, Shane W. Davis +1
We perform 3D radiation-magnetohydrodynamic simulations of the evolution of the fallback debris after a tidal disruption event. We focus on studying the effects of magnetic fields…

Multi-band Emission from Star-Disk Collision and Implications for Quasi-Periodic Eruptions
Xiaoshan Huang, Itai Linial, Yan-Fei Jiang
We perform two-dimensional, multi-group radiation hydrodynamic simulations to explore the observational properties of a solar-like star colliding with an accretion disk around a su…
