APOGEE discovery of a chemically atypical star disrupted from NGC 6723 and captured by the Milky Way bulge
José G. Fernández-Trincado, Timothy C. Beers, Dante Minniti +26
The central (`bulge') region of the Milky Way is teeming with a significant fraction of mildly metal-deficient stars with atmospheres that are strongly enriched in cyanogen ($^{12}…
RR Lyrae variables in Messier 53: Near-infrared Period--Luminosity relations and the calibration using Gaia Early Data Release 3
Anupam Bhardwaj, Marina Rejkuba, Richard de Grijs +6
We present new near-infrared, , Period--Luminosity relations (PLRs) for RR Lyrae variables in the Messier 53 (M53 or NGC 5024) globular cluster. Multi-epoch observat…
The search for extratidal star candidates around Galactic globular clusters NGC 2808, NGC 6266, and NGC 6397 with {\textit{Gaia}} DR2 astrometry
Richa Kundu, Camila Navarrete, José G. Fernández-Trincado +5
Context. Extratidal stars are stellar bodies that end up outside the tidal radius of a cluster as a result of internal processes or external forces acting upon it. The presence and…
A theoretical framework of BL Her stars. I. Effect of metallicity and convection parameters on period-luminosity and period-radius relations
Susmita Das, Shashi M. Kanbur, Radoslaw Smolec +3
We present a new grid of convective BL Herculis models using the state-of-the-art 1D non-linear radial stellar pulsation tool MESA-RSP. We investigate the impact of metallicity and…
A study of the stellar photosphere-hydrogen ionisation front interaction in pulsating variables using period-color relations
Susmita Das, Shashi M. Kanbur, Earl P. Bellinger +2
Period-color (PC) relations may be used to study the interaction of the stellar photosphere and the hydrogen ionization front (HIF). RR Lyraes (RRLs) and long period classical Ceph…
Near-infrared Census of RR Lyrae variables in the Messier 3 globular cluster and the Period--Luminosity Relations
Anupam Bhardwaj, Marina Rejkuba, Richard de Grijs +4
We present new near-infrared () time-series observations of RR Lyrae variables in the Messier 3 (NGC 5272) globular cluster using the WIRCam instrument at the 3.6-m Canada F…
