3D MHD Simulations of Accretion onto Stars with Tilted Magnetic and Rotational Axes
M. M. Romanova, A. V. Koldoba, G. V. Ustyugova +3
We present results of global three-dimensional (3D) magnetohydrodynamic (MHD) simulations of accretion onto magnetized stars where both the magnetic and rotational axes of the star…
Excitation of Spin-Orbit Misalignments in Stellar Binaries with Circumbinary Disks: Application to DI Herculis
Kassandra R. Anderson, Dong Lai
The large spin-orbit misalignments in the DI Herculis stellar binary system have resolved the decades-long puzzle of the anomalously slow apsidal precession rate, but raise new que…
Tidal Evolution of Eccentric Binaries Driven by Convective Turbulent Viscosity
Michelle Vick, Dong Lai
Tidal dissipation due to convective turbulent viscosity shapes the evolution of a variety of astrophysical binaries. For example, this type of dissipation determines the rate of or…
Polygram Stars: Resonant Tidal Excitation of Fundamental Oscillation Modes in Asynchronous Stellar Coalescence
Morgan MacLeod, Michelle Vick, Dong Lai +1
The prevalence of binary stars at close separations implies that many of these systems will interact or merge during the binary's lifetime. This paper presents hydrodynamic simulat…
Electromagnetic Torques, Precession and Evolution of Magnetic Inclination of Pulsars
J. J. Zanazzi, Dong Lai
We present analytic calculations of the electromagnetic torques acting on a magnetic neutron star rotating in vacuum, including near-zone torques associated with the inertia of dip…
Low- instabilities in differentially rotating proto-neutron stars with magnetic fields
Wen Fu, Dong Lai
Recent hydrodynamical simulations have shown that differentially rotating neutron stars formed in core-collapse supernovae may develop global non-axisymmetric instabilities even wh…
