Bell Plesset Effects on Rayleigh Taylor Instability of Three Dimensional Spherical Geometry
Xilai Li, Yilin Wu, Zhengnuo Chen +2
We develop a weakly nonlinear, multi-mode theory for the Rayleigh-Taylor instability (RTI) on a time-varying spherical interface, fully incorporating mode couplings and the Bell-Pl…

Engulfment of Eccentric Planets by Giant Stars: Hydrodynamics and Light Curves
Mengqi Yang, Dong Lai, Fuyuan Wu +1
Recent observations suggest that planetary engulfment by a giant star may produce radiation that resembles subluminous red novae. We present three-dimensional hydrodynamical simula…
