Massive binary stars and the kinematics of Young Massive Clusters

, 2013
Located in the Large Magellanic Cloud, R136 is a rare example of a nearby young and dense massive star cluster in which individual stars can be resolved. Often suggested as a globular cluster in formation, its study is of great interest and promises to provide insights into the early dynamical evolution of massive star clusters.

Spin–Orbit Alignment in Merging Binary Black Holes Following Collisions with Massive Stars

The Astrophysical Journal Letters
Merging binary black holes (BBHs) formed dynamically in dense star clusters are expected to have uncorrelated spin–orbit orientations since they are assembled through many random interactions.

Spatial segregation of massive clusters in a simulation of colliding dwarf galaxies

The Open Journal of Astrophysics
The collective properties of star clusters are investigated using a simulation of the collision between two dwarf galaxies. The characteristic power law of the cluster mass function, N(M), with a logarithmic slope d\log N/d\log M ~ -1, is present from ...

Young Massive Clusters in the Galactic Center

, 2004
The three young clusters in the Galactic Center represent the closest examples of massive starbursts and they define the upper mass limit of the Galactic cluster mass functions. In this review, I describe the characteristics and content of the Arches, Quintuplet, and Central clusters. They each are more massive than any other cluster in the Galaxy, and

Using Detailed Single-star and Binary-evolution Models to Probe the Large Observed Luminosity Spread of Red Supergiants in Young Open Star Clusters

The Astrophysical Journal Letters
Red supergiants (RSGs) represent a late evolutionary stage of massive stars. Recent observations reveal that the observed luminosity range of RSGs in young open clusters is wider than expected from single-star evolution models.

Assembling GW231123 in Star Clusters through the Combination of Stellar Binary Evolution and Hierarchical Mergers

The Astrophysical Journal Letters
GW231123 is the most massive binary black hole (BBH) merger detected to date by the LIGO–Virgo–KAGRA collaboration. With at least one black hole (BH) in the upper mass gap and both BHs exhibiting high spins ( χ _1,2  ≳ 0.8), this event challenges ...
