Long Photometric Cycles in Double Periodic Variables from Nodal Precession of a Tilted Accretion Disk
Cheng-Liang Jiao, Er-gang Zhao, Liying Zhu +1
We investigate whether the long photometric cycles observed in double-periodic variables (DPVs) can arise from nodal precession of a tilted accretion disk driven by the tidal torqu…

Spherically Symmetric Accretion with Self-Gravity: Analytical Formulae and Numerical Validation
Cheng-Liang Jiao, Er-gang Zhao, Liying Zhu +1
Spherically symmetric accretion incorporating self-gravity constitutes a three-point boundary value problem (TPBVP) governed by constraints at the outer boundary, sonic point, and…
