    Gradient of mean mass of a star in the field of globular clusters by Valjarević A.

    Published 2007-01-01
    “…Based on the relevant available data, the distributions of masses and apparent magnitudes of stars belonging to globular star clusters are simulated. The simulations are aimed at examining the influence of the mass-segregation phenomenon on the surface-density profile. …”

    Generalized Schuster law and King’s formula by Živkov V., Ninković S.

    Published 1998-01-01
    “…By varying a particular form of the generalized Schuster density law (the exponent in the denominator equal to 3/2) the authors look for a suitable substitution for King’s density formula usually applied to star clusters and dwarf galaxies. The authors find expressions yielding almost identical density values as King’s formula, but from the mathematical point of view significantly more simple for use.…”

    Black hole mergers from quadruples by Fragione, G, Kocsis, B

    Published 2019
    “…We show that BHs merging through this channel have a significant eccentricity in the LIGO band, typically much larger than BHs merging in isolated binaries and in binaries ejected from star clusters, but comparable to that of merging binaries formed via the gravitational wave capture scenario in clusters, mergers in hierarchical triples, or BH binaries orbiting intermediate-mass BHs in star clusters. …”
