A Supernova Remnant Collision with a Stellar Wind [PDF]

open access: greenThe Astrophysical Journal, 2003
Numerical simulations of the interaction between supernova ejecta and a stellar wind are presented. We follow the temporal evolution of the shock fronts that are formed through such an interaction and determine the velocities, temperatures and densities.

Formation of Stripped Stars from Stellar Collisions in Galactic Nuclei [PDF]

open access: goldThe Astrophysical Journal
Tidal disruption events (TDEs) are an important way to probe the properties of stellar populations surrounding supermassive black holes. The observed spectra of several TDEs, such as ASASSN-14li, show high nitrogen-to-carbon (N/C) abundance ratios ...

The Primary Flare Following a Stellar Collision in a Galactic Nucleus [PDF]

open access: yesThe Astrophysical Journal Letters
High-velocity stellar collisions near supermassive black holes may result in a complete disruption of the stars. The initial disruption can have energies on par with supernovae and power a very fast transient.

Intermediate-mass Black Hole Progenitors from Stellar Collisions in Dense Star Clusters [PDF]

open access: goldThe Astrophysical Journal
Very massive stars (VMSs) formed via a sequence of stellar collisions in dense star clusters have been proposed as the progenitors of massive black hole seeds.

On the stability and collisions in triple stellar systems [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2017
A significant fraction of main sequence stars are part of a triple system. We study the long-term stability and dynamical outcomes of triple stellar systems using a large number of long-term direct N-body integrations with relativistic precession. We find that the previously proposed stability criteria by Eggleton & Kiseleva 1995 and Mardling &

Stellar Collisions in Galactic Nuclei: Impact on Destructive Events Near a Supermassive Black Hole [PDF]

open access: yesThe Astrophysical Journal, 2023
The centers of galaxies host both a supermassive black hole and a dense stellar cluster. Such an environment should lead to stellar collisions, possibly at very high velocities so that the total energy involved is of the same order as supernova ...

Stellar Collisions in the Galactic Center: Massive Stars, Collision Remnants, and Missing Red Giants [PDF]

open access: yesThe Astrophysical Journal, 2023
Like most galaxies, the Milky Way harbors a supermassive black hole (SMBH) at its center, surrounded by a nuclear star cluster. In this dense star cluster, direct collisions can occur between stars before they evolve off the main sequence.

Building Blue Stragglers with Stellar Collisions [PDF]

open access: yesProceedings of the International Astronomical Union, 2007
The evolution of stellar collision products in cluster simulations has usually been modelled using simplified prescriptions. Such prescriptions either replace the collision product with an (evolved) main sequence star, or assume that the collision ...
