Red giant stellar collisions in the Galactic Centre [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We show that collisions with stellar--mass black holes can partially explain the absence of bright giant stars in the Galactic Centre, first noted by Genzel et al, 1996. We show that the missing objects are low--mass giants and AGB stars in the range 1-3 M$_{\odot}$.

The Astrophysical JournalIn galactic centers, stars and binaries can be injected into low-angular-momentum orbits, resulting in close encounters with the central supermassive black hole (SMBH).

Evolution of stellar collision products in open clusters. II. A grid of low-mass collisions [PDF]
Astronomy & Astrophysics, 2008 In a companion paper we studied the detailed evolution of stellar collision products that occurred in an $N$-body simulation of the old open cluster M67 and compared our detailed models to simple prescriptions. In this paper we extend this work by studying the evolution of the collision products in open clusters as a function of mass and age of the ...

THE TRIPLE EVOLUTION DYNAMICAL INSTABILITY: STELLAR COLLISIONS IN THE FIELD AND THE FORMATION OF EXOTIC BINARIES [PDF]
, 2012 Physical collisions and close approaches between stars play an important role in the formation of exotic stellar systems. Standard theories suggest that collisions are rare, occurring only via random encounters between stars in dense clusters. We present

Evolution of the remnants of stellar collisions
, 2008 Collisions between stars occur naturally in star clusters. The outcome of such collisions is a new single star that may have peculiar properties that affect its subsequent evolution. For low mass stars, such merger events are a possible formation channel for blue straggler stars, stars more massive than expected for a starcluster of a given age.

The Astrophysical JournalNGC 1052-DF2 and -DF4 are two ultradiffuse galaxies that have been reported as deficient in dark matter and associated with the same galaxy group. Recent findings suggest that DF2 and DF4 are part of a large linear substructure of dwarf galaxies that ...

Overview of Numerical Simulations for Calculating In-Plasma β-Decay Rates in the Framework of PANDORA Project [PDF]
EPJ Web of Conferences, 2023 β-decay rates are essential inputs in stellar nucleosynthesis models to explain observed nuclear abundances. While current models continue to use terrestrial values, experiments in storage rings indicate strong divergence between decay rates of neutral ...

Stellar Collisions in Galactic Nuclei: Impact on Destructive Events Near a Supermassive Black Hole
The 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 ...
