New Candidate Massive Clusters from 2MASS [PDF]

, 2013
Massive stars are important for the evolution of the interstellar medium. The detailed study of their properties (such as mass loss, rotation, magnetic fields) is enormously facilitated by samples of these objects in young massive galactic star clusters.

PHANGS: constraining star formation time-scales using the spatial correlations of star clusters and giant molecular clouds

, 2023
In the hierarchical view of star formation, giant molecular clouds (GMCs) undergo fragmentation to form small-scale structures made up of stars and star clusters.

Be stars in young clusters

The Astrophysical Journal, 1994
Photometric Ha and HP line indices for 71 B stars in seven galactic clusters are presented. Some stars in three of the clusters were observed at two epochs. Using these data nine Be stars were identified. Three of them were previously detected as emission-line stars, while six do not appear to have been previously recognized as such.

Dynamical Mass Estimates for Two Luminous Star Clusters in Galactic Merger Remnants [PDF]

, 2006
We present high-dispersion spectra of two extremely massive star clusters in galactic merger remnants, obtained using the UVES spectrograph mounted on the ESO Very Large Telescope.

Old star clusters in the FSR catalogue [PDF]

, 2010
We investigate the old star clusters in the sample of cluster candidates from the Froebrich, Scholz & Raftery (FSR) list. Based on photometry from the Two-Micron All-Sky Survey, we generated decontaminated colour-magnitude and colour-colour diagrams ...

Star clusters as age tracers of the age-metallicity relation of the small magellanic cloud [PDF]

, 2009
In my Thesis, I determined ages of Small Magellanic Cloud (SMC) star clusters that have formed during the galaxys entire lifetime.

HOW FAR CAN GET FRB PROGENITOR NEUTRON STARS FROM THEIR BIRTHPLACE?

Вестник. Серия физическая, 2021
The recent studies show evidence of magnetars – young neutron stars being good candidates of fast radio birth sources. Neutron stars can form as remnants of type II supernovae explosions of young stars.

THE EVOLUTIONARY TRACKS OF YOUNG MASSIVE STAR CLUSTERS [PDF]

The Astrophysical Journal, 2014
Stars mostly form in groups consisting of a few dozen to several ten thousand members. For 30 years, theoretical models provide a basic concept of how such star clusters form and develop: they originate from the gas and dust of collapsing molecular clouds.

Star clusters in unperturbed spiral galaxies [PDF]

, 2008
Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.
