Open-cluster density profiles derived using a kernel estimator [PDF]
, 2016 Surface and spatial radial density profiles in open clusters are derived using a kernel estimator method. Formulae are obtained for the contribution of every star into the spatial density profile.

A comparative study on the reliability of open cluster parameters [PDF]
, 2015 Context. Open clusters are known as excellent tracers of the structure and chemical evolution of the Galactic disk, however, the accuracy and reliability of open cluster parameters is poorly known. Aims: In recent years, several studies aimed to present

Improving the open cluster census. II. An all-sky cluster catalogue with Gaia DR3 [PDF]
Astronomy & Astrophysics, 2023 Data from the Gaia satellite are revolutionising our understanding of the Milky Way. With every new data release, there is a need to update the census of open clusters. We aim to conduct a blind, all-sky search for open clusters using 729 million sources

Rotation and Lithium Confirmation of a 500 pc Halo for the Open Cluster NGC 2516 [PDF]
Astronomical Journal, 2021 Recent analyses of the Gaia data have identified diffuse stellar populations surrounding nearby open clusters. It is important to verify that these “halos,” “tails,” and “strings” are of similar ages and compositions as stars in the denser part of the ...

Stellar Radial Velocities in the Old Open Cluster M67 (NGC 2682). II. The Spectroscopic Binary Population [PDF]
, 2021 We present and analyze 120 spectroscopic binary and triple cluster members of the old (4 Gyr) open cluster M67 (NGC 2682). As a cornerstone of stellar astrophysics, M67 is a key cluster in the WIYN Open Cluster Study (WOCS); radial-velocity (RV ...

3D kinematics and age distribution of the open cluster population [PDF]
Astronomy & Astrophysics, 2020 Context. Open clusters (OCs) trace the evolution of the Galactic disc with great accuracy. Gaia and large ground-based spectroscopic surveys make it possible to determine their properties and study their kinematics with unprecedented precision. Aims.

The disintegrating old open cluster Czernik 3 [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We have performed a detailed analysis of the Czernik 3 (Cz3) open cluster by using deep near-infrared photometry taken with TIRCAM2 on the 3.6 m Devasthal optical telescope along with the recently available high-quality proper motion data from the Gaia

WIYN Open Cluster Study. LXXXII. Radial-velocity Measurements and Spectroscopic Binary Orbits in the Open Cluster NGC 7789 [PDF]
Astronomical Journal, 2020 We present an extensive time-series radial-velocity (RV) survey of stars in the rich open cluster NGC 7789 (1.6 Gyr, [Fe/H] = +0.02). The stellar sample lies within an 18′ circular radius from the cluster center (10 pc in projection, or about 2 core ...

Improving the open cluster census [PDF]
Astronomy & Astrophysics, 2020 Context. The census of open clusters in the Milky Way is in a never-before seen state of flux. Recent works have reported hundreds of new open clusters thanks to the incredible astrometric quality of the Gaia satellite, but other works have also reported
