A theoretical framework for BL Her stars III. A case study: Robust light curve optimisation in the LMC
Susmita Das, László Molnár, Gábor B. Kovács +8
We carry out an extensive light curve comparison of BL Her stars using observations from Gaia DR3 and stellar pulsation models computed using MESA-RSP with the goal to obtain the b…
Multi-wavelength Photometric Study of RR Lyrae Variables in the Globular Cluster NGC 5272 (Messier 3)
Nitesh Kumar, Anupam Bhardwaj, Harinder P. Singh +3
We present a comprehensive photometric study of RR Lyrae stars in the M3 globular cluster, utilising a vast dataset of 3140 optical () CCD images spanning 35 years from astr…
Discovery of RR Lyrae in the Ultra-Faint Dwarf Galaxy Virgo III
Chow-Choong Ngeow, Anupam Bhardwaj
Virgo III is a newly discovered ultra-faint dwarf (UFD) candidate, and finding RR Lyrae associated with this galaxy is important to constrain its distance. In this work, we present…
Bridging theory and observations in stellar pulsations: The impact of convection and metallicity on the instability strips of Classical and Type-II Cepheids
Mami Deka, Earl P. Bellinger, Shashi M. Kanbur +5
The effect of metallicity on the theoretical and empirical period-luminosity (PL) relations of Cepheid variables is not well understood and remains a highly debated issue. Here, we…
Stellar Variability and Distance Indicators in the Near-infrared in Nearby Galaxies. I. RR Lyrae and Anomalous Cepheids in Draco dwarf spheroidal
Anupam Bhardwaj, Marina Rejkuba, Chow-Choong Ngeow +4
Draco dwarf Spheroidal galaxy (dSph) is one of the nearest and the most dark matter dominated satellites of the Milky Way. We obtained multi-epoch near-infrared (NIR, ) obse…
The Hertzsprung progression of Classical Cepheids in the Gaia era
Marcella Marconi, Giulia De Somma, Roberto Molinaro +6
A new fine grid of nonlinear convective pulsation models for the so-called "bump Cepheids" is presented to investigate the Hertzprung progression (HP) phenomenon shown by their lig…
