Asymmetrical thermonuclear supernovae triggered by the tidal disruption of white dwarfs

Pavan Vynatheya, Luc Dessart, Taeho Ryu +1

In a dense star cluster core, a tidal disruption event (TDE) of a white dwarf (WD) can occur if the WD passes within the tidal radius of an intermediate-mass black hole (IMBH). Ver…

The collision and merger products of stars do not look alike: A magnetohydrodynamics comparison

Pavan Vynatheya, Taeho Ryu, Chen Wang +2

A significant fraction of stars experience close interactions, including collisions resulting from gravitational encounters and mergers within close binary systems. These processes…

Simulating the tidal disruption of stars by stellar-mass black holes using moving-mesh hydrodynamics

Pavan Vynatheya, Taeho Ryu, Ruediger Pakmor +2

In the centers of dense star clusters, close encounters between stars and compact objects are likely to occur. We study tidal disruption events of main-sequence (MS) stars by stell…

Quadruple-star systems are not always nested triples: a machine learning approach to dynamical stability

Pavan Vynatheya, Rosemary A. Mardling, Adrian S. Hamers

The dynamical stability of quadruple-star systems has traditionally been treated as a problem involving two `nested' triples which constitute a quadruple. In this novel study, we e…

Algebraic and machine learning approach to hierarchical triple-star stability

Pavan Vynatheya, Adrian S. Hamers, Rosemary A. Mardling +1

We present two approaches to determine the dynamical stability of a hierarchical triple-star system. The first is an improvement on the Mardling-Aarseth stability formula from 2001…

How important is secular evolution for black hole and neutron star mergers in 2+2 and 3+1 quadruple-star systems?

Pavan Vynatheya, Adrian S. Hamers

Mergers of black holes (BHs) and neutron stars (NSs) result in the emission of gravitational waves that can be detected by LIGO. In this paper, we look at 2+2 and 3+1 quadruple-sta…
