A Comparative Study of Multiwavelength Theoretical and Observed Light Curves of Cepheid Variables
Anupam Bhardwaj, Shashi M. Kanbur, Marcella Marconi +3
We analyse the theoretical light curves of Cepheid variables at optical ({\it UBVRI}) and near-infrared ({\it JKL}) wavelengths using the Fourier decomposition and principal compon…
Period-Color and Amplitude-Color Relations at Maximum and Minimum Light for RR Lyrae Stars in the SDSS Stripe 82 Region
Chow-Choong Ngeow, Shashi M. Kanbur, Anupam Bhardwaj +2
Investigation of period-color (PC) and amplitude-color (AC) relations at the maximum and minimum light can be used to probe the interaction of the hydrogen ionization front (HIF) w…
Period-Luminosity relations derived from the OGLE-III First-overtone mode Cepheids in the Magellanic Clouds
Anupam Bhardwaj, Chow-Choong Ngeow, Shashi M. Kanbur +1
We present multi-band Period-Luminosity (PL) relations for first-overtone mode Cepheids in the Small Magellanic Cloud (SMC). We derive optical band PL relations and the Wesenheit f…
Large Magellanic Cloud Near-Infrared Synoptic Survey. III. A Statistical Study of Non-Linearity in the Leavitt Laws
Anupam Bhardwaj, Shashi M. Kanbur, Lucas M. Macri +3
We present a detailed statistical analysis of possible non-linearities in the Period-Luminosity (P-L), Period-Wesenheit (P-W) and Period-Color (P-C) relations for Cepheid variables…
