Dynamical and Photometric Analysis of NGC 146 and King 14: Evidence for a Co-Moving, Unbound Cluster Pair
D. Bisht, Ing-Guey Jiang, W. H. Elsanhoury +9
To understand the nature of the NGC 146-King 14 cluster pair, we conducted a detailed photometric, astrometric, and dynamical study using multiwavelength data from Gaia DR3, Pan-ST…
Kinematics of High-Velocity Stars Utilizing LAMOST and Gaia DR3 Archives within 100 kpc
W. H. Elsanhoury
The kinematic parameters identified from high-velocity stars situated within 100 kpc are examined and analyzed. We included three high velocity programs comprising 591, 87, and 519…
Deep Photometric and Astrometric Investigation of the Non-relaxed Star Cluster Stock 3 using Gaia DR3
A. Ahmed, Amira R. Youssef, M. S. El-Nawawy +1
The study presents both photometric and kinematic analyses of the non-relaxed open cluster Stock 3 with Gaia DR3 which found to be positioned at 2.945 0.700 kpc and having an…
Enhanced kinematics and distribution characteristics of Upper Scorpius and Ophiuchus associations based on Gaia DR3
W. H. Elsanhoury
The kinematics within the Solar vicinity have revealed interesting features relevant to both stellar and Galactic structures. This study examines three stellar associations in the…
Deeply Comprehensive Astrometric, Photometric, and Kinematic Studies of the Three OCSN Open Clusters with Gaia DR3
W. H. Elsanhoury, Haroon A. A, E. A. Elkholy +1
In this study, we considered the optical wavelength of Gaia DR3 to analyze poorly studied three newly open star clusters namely OCSN 203, OCSN 213, and OCSN 244 clusters with ASTEC…
Kinematical and Ellipsoidal Properties of the Inner-Halo Hot Subdwarfs Observed in Gaia DR3 and LAMOST DR7
W. H. Elsanhoury
Here, we report the kinematical parameters of inner-halo hot subdwarfs located within (d lower than or equal 15 kpc) at high Galactic latitudes (b^o greater than or equal 20). The…
