General Polytropic Magnetofluid under Self-Gravity: Voids and Shocks
Yu-Qing Lou, Ren-Yu Hu
We study the self-similar magnetohydrodynamics (MHD) of a quasi-spherical expanding void (viz. cavity or bubble) in the centre of a self-gravitating gas sphere with a general polyt…
Magnetized massive stars as magnetar progenitors
Ren-Yu Hu, Yu-Qing Lou
The origin of ultra-intense magnetic fields on magnetars is a mystery in modern astrophysics. We model the core collapse dynamics of massive progenitor stars with high surface magn…
Rebound Shock Breakouts of Exploding Massive Stars: A MHD Void Model
Ren-Yu Hu, Yu-Qing Lou
With a self-similar magnetohydrodynamic (MHD) model of an exploding progenitor star and an outgoing rebound shock and with the thermal bremsstrahlung as the major radiation mechani…
Self-Similar Polytropic Champagne Flows in H II Regions
Ren-Yu Hu, Yu-Qing Lou
We explore large-scale hydrodynamics of H II regions for various self-similar shock flows of a polytropic gas cloud under self-gravity and with quasi-spherical symmetry. We formula…
