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…
Long-period maser-bearing Miras in the Galactic center: period-luminosity relations and extinction estimates
M. O. Lewis, R. Bhattacharya, L. O. Sjouwerman +5
We establish a sample of 370 Mira variables that are likely near the Galactic center (GC). The sources have been selected from the OGLE and BAaDE surveys based on their sky coordin…
Carbon- and Oxygen-rich Asymptotic Giant Branch (AGB) stars in the Bulge Asymmetries and Dynamical Evolution (BAaDE) survey
Megan O. Lewis, Ylva M. Pihlström, Loránt O. Sjouwerman +2
Detections of SiO masers from the Bulge Asymmetries and Dynamical Evolution (BAaDE) survey more tightly define the region where Oxygen-rich (O) Asymptotic Giant Branch (AGB) stars…
44 GHz Class I Methanol (CHOH) Maser Survey in the Galactic Center
Bridget McEwen, Loránt Sjouwerman, Ylva Pihlström
We report on a large 44 GHz ( A) methanol (CHOH) maser survey of the Galactic Center (GC). The Karl G. Jansky Very Large Array was used to search for CHOH mase…
