Mapping the Inner Milky Way with Infrared-Derived Distances to AGB Stars
Rajorshi Bhattacharya, Subhajit Kar, Loránt O. Sjouwerman +1
The structure and evolution of the Milky Way (MW) can be traced with distance estimates to the evolved stellar populations in the inner galactic region. However, direct astrometric…
Large Magellanic Cloud Globular Clusters in the Near-infrared. I. RR Lyrae in Reticulum
Anupam Bhardwaj, Susmita Das, Prashant Nishad +10
Reticulum is an old, metal-poor, and sparsely populated globular cluster in the outer regions of the Large Magellanic Cloud (LMC) and hosts a rich population of RR Lyrae stars. Bei…
Classification of Wolf Rayet stars using Ensemble-based Machine Learning algorithms
Subhajit Kar, Rajorshi Bhattacharya, Ramkrishna Das +2
We develop a robust Machine Learning classifier model utilizing the eXtreme-Gradient Boosting (XGB) algorithm for improved classification of Galactic Wolf-Rayet (WR) stars based on…
Detection of high-frequency pulsation in WR 135: investigation of stellar wind dynamics
Subhajit Kar, Ramkrishna Das, Blesson Mathew +2
We report the detection of high-frequency pulsations in WR\,135 from short cadence (10\,minutes) optical photometric and spectroscopic time series surveys. The harmonics up to $6^{…
Investigation of [KSF2015] 1381-19L, a WC9-type star in the high extinction Galactic region
Subhajit Kar, Ramkrishna Das, Tapas Baug
We report a multi-wavelength study of the Wolf Rayet (WR) star: [KSF2015] 1381-19L, which is located in the solar metallicity region (Z=0.014) of the Milky Way Galaxy, strongly obs…
