Berkeley 32: A Metal-poor and Dynamically Evolved Open Cluster with Evidence of Radial Migration
Deniz Cennet Ãınar, 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…
