Milky Way Star Clusters and Gaia: A Review of the Ongoing Revolution [PDF]

open access: yesUniverse, 2022
The unprecedented quality of the astrometric measurements obtained with the ESA Gaia spacecraft have initiated a revolution in Milky Way astronomy. Studies of star clusters in particular have been transformed by the precise proper motions and parallaxes ...

The evolution of star clusters: the resolved-star approach

open access: yesAstrophysics and Space Science, 2009
We present the first results of a new technique to detect, locate, and characterize young dissolving star clusters. Using HST/ACS archival images of the nearby galaxy IC2574, we performed stellar PSF photometry and selected the most massive stars as our first test sample.

The formation of star clusters [PDF]

open access: yes, 2003
The ability of HST to resolve objects ten times smaller than possible from the ground has rejuvenated the study of young star clusters. A recurrent morphological theme found in nearby resolved sytems is the observation of young (typically 1 - 10 Myr), massive (10**3 - 10**4 M_sun), compact (rho ~ 10**5 M_sun/pc**3) clusters which have evacuated the gas

UOCS. XIII. Study of the Far-ultraviolet Bright Stars in the Open Cluster NGC 2420 Using AstroSat

open access: yesThe Astrophysical Journal
We present the study of four far-ultraviolet (FUV) bright stars in the field of the open cluster NGC 2420 using the Ultra Violet Imaging Telescope mounted on AstroSat.

Binary Star Evolution in Different Environments: Filamentary, Fractal, Halo, and Tidal Tail Clusters

open access: yesThe Astronomical Journal, 2023
Using membership of 85 open clusters from previous studies based on Gaia Data Release 3 data, we identify binary candidates in the color–magnitude diagram for systems with mass ratio q > 0.4.

Feedback in Extragalactic Star Clusters (FEAST): Spectral Energy Distributions and the Physical Properties of Star Clusters in NGC 628 with CIGALE

open access: yesThe Astrophysical Journal
With Hubble Space Telescope and James Webb Space Telescope (JWST) observations of NGC 628 spanning 0.3–7.7 μ m, we fit the spectral energy distributions of over 12,000 optically selected star clusters, emerging young star clusters (eYSCs), and MIRI ...

Searching for New Globular Clusters in M31 with Gaia EDR3

open access: yesThe Astrophysical Journal, 2023
We have found 50 new globular cluster (GC) candidates around M31 with Gaia Early Data Release 3 (EDR3), with the help of Pan-STARRS1 DR1 magnitudes and Pan-Andromeda Archaeological Survey (PAndAS) images.

UOCS-XIX. A Multiwavelength Study of Open Cluster Trumpler 5: Cluster Properties and Exotic Populations

open access: yesThe Astronomical Journal
Trumpler 5 is a populous, intermediate-age (∼3 Gyr), metal-poor ([Fe/H] ∼ −0.4) open cluster, located at a distance of approximately ∼3050 pc. This is a well-studied cluster for its broadened main-sequence (MS) and blue straggler star (BSS) population ...

A Systematic Analysis of Star Cluster Disruption by Tidal Shocks. II. Predicting Star Cluster Dissolution Rates from a Time-series Analysis of Their Tidal Histories

open access: yesThe Astrophysical Journal
Most of the dynamical mass loss from star clusters is thought to be caused by the time variability of the tidal field (“tidal shocks”). Systematic studies of tidal shocks have been hampered by the fact that each tidal history is unique, implying both a ...

Open Cluster Study Using Gaia. I. Membership and Cluster Properties

open access: yesThe Astrophysical Journal
Star clusters are interesting laboratories to study star formation, single and binary stellar evolution, and stellar dynamics. We have used the exquisite data from Gaia’s Data Release 3 (DR3) to study 21 relatively rich and nearby open clusters with ...
