Photometric Study of RR Lyrae Star TV Lyn

Abstract

In this research, we are reporting the light curve of RR Lyrae type variable star TV Lyn. This star is observed in the northern hemisphere and its coordinates are 07:33:31.7 +47:48:09.8. We have used data from Las Cumbres Observatory (LCO) which consists of a worldwide network of robotic telescopes. Photometric measurements were conducted using the SBIG 6303 0.4-meter telescope with a field of view of 29’x19’. Depending on what the color of a star is when different filters are applied to it, the luminosity will change accordingly. Our data consists of four filters, Bessell B (Blue), Bessell V (visual), SDSS-I (Infrared), and PAN-STARRS-Z (Near Infrared). Results show that this star has a variability period of 0.2407±0.002 days, metallicity -1.49, and located at a distance of 1362±118 pc. We have used an estimate of the reddening E(B-V) as 0.08. This research is a part of an Our Solar Sibling Project by an undergraduate student with the help of a faculty advisor and an Our Solar Sibling Project Investigator.
