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

open access: yesВестник. 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.

Nuclear star clusters [PDF]

open access: yesProceedings of the International Astronomical Union, 2009
AbstractThe centers of most galaxies in the local Universe are occupied by compact, barely resolved sources. Based on their structural properties, position in the Fundamental Plane, and integrated spectra, these sources clearly have a stellar origin. They are therefore called ‘nuclear star clusters’ (NCs) or ‘stellar nuclei’.

Z-FIRE: ISM properties of the z = 2.095 COSMOS Cluster [PDF]

open access: yes, 2015
We investigate the ISM properties of 13 star-forming galaxies within the z~2 COSMOS cluster. We show that the cluster members have [NII]/Ha and [OIII]/Hb emission-line ratios similar to z~2 field galaxies, yet systematically different emission-line ...

Radiation pressure in super star cluster formation [PDF]

open access: yes, 2017
The physics of star formation at its extreme, in the nuclei of the largest and densest star clusters in the universe - potential massive black hole nurseries - has for decades eluded scrutiny.

The embedded cluster or association Trumpler 37 in IC1396: a search for evolutionary constraints [PDF]

open access: yes, 2012
It is currently widely accepted that open star clusters and stellar associations result from the evolution of embedded star clusters. Parameters such star formation efficiency, time-scale of gas removal and velocity dispersion can be determinants of ...

DISCOVERY OF A FAINT OUTER HALO MILKY WAY STAR CLUSTER IN THE SOUTHERN SKY [PDF]

open access: yes, 2015
We report the discovery of a new, low-luminosity star cluster in the outer halo of the Milky Way. High-quality gr photometry is presented, from which a color–magnitude diagram is constructed, and estimates of age, [Fe/H], [α/Fe], and distance are derived.

SIGNATURES OF STAR CLUSTER FORMATION BY COLD COLLAPSE [PDF]

open access: yesAstrophysical Journal, 2015
Subvirial gravitational collapse is one mechanism by which star clusters may form. Here we investigate whether this mechanism can be inferred from observations of young clusters.

Planetary systems in star clusters [PDF]

open access: yesProceedings of the International Astronomical Union, 2014
AbstractIn the solar neighborhood, where the typical relaxation timescale is larger than the cosmic age, at least 10% to 15% of Sun-like stars have planetary systems with Jupiter-mass planets. In contrast, dense star clusters, characterized by frequent close encounters, have been found to host very few planets.

Star cluster formation in Orion A [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2020
Abstract We introduce new analysis methods for studying the star cluster formation processes in Orion A, especially examining the scenario of a cloud–cloud collision. We utilize the CARMA–NRO Orion survey 13CO (1–0) data to compare molecular gas to the properties of young stellar objects from the SDSS III IN-SYNC survey. We show that the
