Large Magellanic Cloud Globular Clusters in the Near-infrared. I. RR Lyrae in Reticulum
Anupam Bhardwaj, Susmita Das, Prashant Nishad +10
Reticulum is an old, metal-poor, and sparsely populated globular cluster in the outer regions of the Large Magellanic Cloud (LMC) and hosts a rich population of RR Lyrae stars. Bei…
Self-Consistent Nonlinear Classical Cepheid Pulsations During Stellar Evolution with MESA
Ebraheem Farag, Earl P. Bellinger, Philip Mocz +5
We extend the time-dependent convection treatment in \code{MESA} by introducing eddy-viscous damping. This software change brings \code{MESA-TDC} into closer alignment with the rad…
The effect of metallicity on the Leavitt Law using phase-dependent properties of classical Cepheids
Gautam Bhuyan, Shashi Kanbur, Sukanta Deb +5
The absolute calibration of period-luminosity (PL) relations of Cepheids in the Milky Way (MW) and its nearby galaxies has been a cornerstone in determining extragalactic distances…
The light curve model fitting of LMC Cepheids: MESA-RSP versus Stellingwerf's code predictions
M. Deka, M. Marconi, R. Molinaro +9
A major challenge in modeling classical Cepheids is the treatment of convection, particularly its complex interplay with pulsation. This inherently three-dimensional process is typ…
Multiwavelength study of observed and predicted pulsation properties of First overtone Cepheids in the Magellanic Clouds
Kerdaris Kurbah, Shashi M. Kanbur, Sukanta Deb +4
We present a detailed analysis of the light curves and pulsation properties of First Overtone (FO) Cepheids in the Magellanic Clouds (MCs) obtained using observations and predictio…
A theoretical framework for BL Her stars IV. New period-luminosity relations in the Rubin-LSST filters
Susmita Das, László Molnár, Róbert Szabó +5
We present new theoretical light curves in the Rubin-LSST filters for a fine grid of BL Her models computed using MESA-RSP. We also derive new theoretical period-luminosity (PL) an…
