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…
