Linear Bending Wave Propagation in Laminar and Turbulent Disks

The Astrophysical Journal
Bending waves are perhaps the most fundamental and analytically tractable phenomena in warped disk dynamics. In this work, we conduct 3D grid-based, numerical experiments of bending waves in laminar, viscous hydrodynamic and turbulent, weakly magnetized ...

Convective Overstability in Radially Global Protoplanetary Disks. I. Pure Gas Dynamics

The Astrophysical Journal
Protoplanetary disks are prone to several hydrodynamic instabilities. One candidate, convective overstability (COS), can drive radial semiconvection that may influence dust dynamics and planetesimal formation.

Radiation transport methods in star formation simulations

Frontiers in Astronomy and Space Sciences
Radiation transport plays a crucial role in star formation models, as certain questions within this field cannot be accurately addressed without taking it into account. Given the high complexity of the interstellar medium from which stars form, numerical

Direct Numerical Simulations of Oxygen-flame-driven Deflagration-to-detonation Transition in Type Ia Supernovae

The Astrophysical Journal
We present direct numerical simulations demonstrating deflagration-to-detonation transition (DDT) driven by oxygen flames in Type Ia supernova progenitors.

The role of dimensions in gravitating relativistic shear-free fluids

European Physical Journal C: Particles and Fields
We study the dynamics of relativistic shear-free gravitating fluids in higher dimensions for both neutral and charged matter. We reduce the Einstein–Maxwell equations to a single second order nonlinear partial differential equation which contains two ...
