Detecting shock waves in non-fundamental mode RR Lyrae using large sample of spectra in SDSS and LAMOST
Xiao-Wei Duan, Xiao-Dian Chen, Li-Cai Deng +4
Steps toward the nature inside RR Lyrae variables can not only improve our understanding of variable stars but also innovate the precision when we use them as tracers to map the st…
Possible evidence of hydrogen emission in the first-overtone and multi-mode RR Lyrae variables
Xiao-Wei Duan, Xiao-Dian Chen, Li-Cai Deng +4
The nature of shock waves in non-fundamental mode RR Lyrae stars remains a mystery because of limited spectroscopic observations. We apply a pattern recognition algorithm on spectr…
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…
High-precision distance measurements with classical pulsating stars
Anupam Bhardwaj
Classical Cepheid and RR Lyrae variables are radially pulsating stars that trace young and old-age stellar populations, respectively. These classical pulsating stars are the most s…
