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…
The stellar photosphere-hydrogen ionization front interaction in Classical Pulsators: a theoretical explanation for observed period-colour relations
Susmita Das, Shashi M. Kanbur, Earl P. Bellinger +6
Period-colour and amplitude-colour (PCAC) relations can be used to probe both the hydrodynamics of outer envelope structure and evolutionary status of Cepheids and RR Lyraes. In th…
Light Curve Parameters of Cepheid and RR Lyrae Variables at Multiple Wavelengths Models vs. Observations
Harinder P. Singh, Susmita Das, Anupam Bhardwaj +2
We present results from a comparative study of light curves of Cepheid and RR Lyrae stars in the Galaxy and the Magellanic Clouds with their theoretical models generated from the s…
On the variation of light curve parameters of RR Lyrae variables at multiple wavelengths
Susmita Das, Anupam Bhardwaj, Shashi M. Kanbur +2
We present a detailed light curve analysis of RR Lyrae variables at multiple wavelengths using Fourier decomposition method. The time-series data for RR Lyrae variables in the Gala…
