Berkeley 32: A Metal-poor and Dynamically Evolved Open Cluster with Evidence of Radial Migration

Deniz Cennet Çınar, D. Bisht, Ing-Guey Jiang +3

The study uses Gaia astrometry and Gaia-ESO spectroscopy to determine the age, metallicity, orbit, binary fraction, and dynamical state of the old, metal-poor open cluster Berkeley…

Blue Straggler Stars in Berkeley 18: A Multiwavelength Study of Their Physical Properties and Dynamical Evolution

D. Bisht, Ing-Guey Jiang, K. Belwal +7

Berkeley~18 is an old open cluster in the outer Galactic disk that hosts a population of blue straggler stars (BSSs). We present a comprehensive multiwavelength analysis of its BSS…

Multiwavelength Study of Blue Straggler Stars in Tombaugh 2: Evidence for Binary Mass Transfer and Constraints on Cluster Dynamical State

D. Bisht, Ing-Guey Jiang, K. Belwal +7

We present a focused multiwavelength study of blue straggler stars (BSSs) in the intermediate-age open cluster Tombaugh 2, located in the outer Galactic disk, to constrain the domi…

The Transit Timing and Transmission Spectrum of Hot Jupiter WASP-43 b from a decade of Multi-band Transit Follow-up Observations

Napaporn A-thano, Supachai Awiphan, Eamonn Kerins +21

We present a new set of 35 transit light curves of the hot Jupiter WASP-43~b, obtained through the SPEARNET network. These datasets were analyzed together with previously published…

Investigation of Transit Timing and an Optical Transmission Spectrum of the Hot Jupiter WASP-11 b

Napaporn A-thano, Supachai Awiphan, Eamonn Kerins +15

WASP-11~b/HAT-P-10~b is an inflated hot Jupiter, which has a low density that makes it a good target for atmospheric studies using the transmission spectroscopy technique. In this…

Time-Series Photometric Detection and Physical Characterization of Variable Stars in Four Intermediate- to Old-Age Galactic Open Clusters

K. Belwal, D. Bisht, Ing-Guey Jiang +4

We present a ground-based time-series photometric study of stellar variability in four intermediate- to old-age open clusters NGC 2192, NGC 2266, NGC 2509, and IC 1369 based on hig…
