Tidal tails in the disintegrating open cluster NGC 752

Souradeep Bhattacharya, Manan Agarwal, Khushboo K. Rao +1

We utilize the robust membership determination algorithm, ML-MOC, on the precise astrometric and deep photometric data from Gaia Early Data Release 3 within a region of radius 5$^{…

Determination of dynamical ages of open clusters through the A parameter -- I

Khushboo K. Rao, Kaushar Vaidya, Manan Agarwal +1

The sedimentation level of blue straggler stars (BSS) has been shown to be a great tool to investigate the dynamical states of globular clusters (GCs). The area enclosed between th…

The survey of planetary nebulae in Andromeda (M31) III. Constraints from deep planetary nebula luminosity functions on the origin of the inner halo substructures in M31

Souradeep Bhattacharya, Magda Arnaboldi, Ortwin Gerhard +4

The Andromeda (M31) galaxy displays several substructures in its inner halo whose origin as remnants of accreted satellites or perturbations of the pre-existing disc are encoded in…

ML-MOC: Machine Learning (kNN and GMM) based Membership Determination for Open Clusters

Manan Agarwal, Khushboo K. Rao, Kaushar Vaidya +1

The existing open cluster membership determination algorithms are either prior dependent on some known parameters of clusters or are not automatable to large samples of clusters. I…

Blue Straggler Populations of Seven Open Clusters with Gaia DR2

Kaushar Vaidya, Khushboo K. Rao, Manan Agarwal +1

Blue straggler stars (BSS) are well studied in globular clusters but their systematic study with secure membership determination is lacking in open clusters. We use Gaia DR2 data t…

The survey of Planetary Nebulae in Andromeda (M31) II. Age-velocity dispersion relation in the disc from Planetary Nebulae

Souradeep Bhattacharya, Magda Arnaboldi, Nelson Caldwell +7

The age-velocity dispersion relation is an important tool to understand the evolution of the disc of the Andromeda galaxy (M31) in comparison with the Milky Way. We use Planetary N…
