Supernovae photometry at OAUNI

Abstract

We analyse photometric data of nine supernovae (SNe) in filters V , R and I obtained during observational campaigns at the OAUNI site in 2016, 2017 and 2023. The calibrated magnitudes of the observed SNe were compared with their respective light curves available in the literature to study their evolution after their maximum brightness. In some cases, the supernova color-color diagnostic diagram was used to determine our observation date and correctly locate our magnitudes on the light curves. For this purpose, the use of supernova light curve templates, as well as reference supernovae, was also helpful. This work allowed us to verify the feasibility of performing precision astronomical photometry at the OAUNI.
