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…
Cepheid Metallicity in the Leavitt Law (C- MetaLL) survey: IV. The metallicity dependence of Cepheid Period-Luminosity relations
E. Trentin, V. Ripepi, R. Molinaro +10
Classical Cepheids (DCEPs) play a fundamental role in the calibration of the extra-galactic distance ladder which eventually leads to the determination of the Hubble constant(…
First spectroscopic investigation of Anomalous Cepheid variables
V. Ripepi, G. Catanzaro, E. Trentin +12
Anomalous Cepheids (ACEPs) are intermediate mass metal-poor pulsators mostly discovered in dwarf galaxies of the Local Group. However, recent Galactic surveys, including the Gaia D…
A multiphase study of classical Cepheids in the Magellanic Clouds- Models and Observations
Kerdaris Kurbah, Shashi M. Kanbur, Sukanta Deb +5
This work presents the study of multiphase relations of classical Cepheids in the Magellanic Clouds for short periods (log P < 1) and long periods (log P > 1). From the analysis, i…
High-resolution Spectroscopic Metallicities of Milky Way Cepheid Standards and their impact on the Leavitt Law and the Hubble constant
Anupam Bhardwaj, Adam G. Riess, Giovanni Catanzaro +10
Milky Way Cepheid variables with accurate {\it Hubble Space Telescope} photometry have been established as standards for primary calibration of the cosmic distance ladder to achiev…
