Discovery of a barium blue straggler star in M67 and sighting of its WD companion*
Harshit Pal, Annapurni Subramaniam, Arumalla B. S. Reddy +1
We report the discovery of a barium blue straggler star (BSS) in M67, exhibiting enhancements in slow neutron-capture (-) process elements. Spectroscopic analysis of two BSSs (W…
The carbon star DY Persei may be a cool R Coronae Borealis variable
D. A. Garcia-Hernandez, N. Kameswara Rao, D. L. Lambert +3
Optical and near-IR photometry suggests that the carbon star DY Persei exhibits fadings similar to those of R Coronae Borealis (RCB) variables. Photometric surveys of the Galaxy an…
Unveiling Vela - Time Variability of Interstellar Lines in the Direction of the Vela Supernova Remnant II. Na D and Ca II
N. Kameswara Rao, David L. Lambert, Arumalla B. S. Reddy +3
In a survey conducted between 2011-12 of interstellar Na I D line profiles in the direction of the Vela supernova remnant, a few lines of sight showed dramatic changes in low veloc…
The evolution of the Milky Way: New insights from open clusters
Arumalla B. S. Reddy, David L. Lambert, Sunetra Giridhar
We have collected high-dispersion echelle spectra of red giant members in the twelve open clusters (OCs) and derived stellar parameters and chemical abundances for 26 species by ei…
Prospecting for chemical tags among open clusters
David L. Lambert, Arumalla B. S. Reddy
Determinations of the chemical composition of red giants in a large sample of open clusters show that the abundances of the heavy elements La, Ce, Nd and Sm but not so obviously Y…
