Optical and Infrared Photometry of the nearby SN 2017cbv

Abstract

Abstract On 2017 March 11, the DLT40 Transient Discovery Survey discovered SN 2017cbv in NGC 5643, a Type 2 Seyfert Galaxy in the Lupus Constellation. SN 2017cbv went on to become a bright Type Ia supernova, with a V max of 11.51 ± 0.05 mag. We present early time optical and infrared photometry of SN 2017cbv covering the rise and fall of over 68 days. We find that SN 2017cbv has a broad light curve Δm 15(B) = 0.88 ± 0.07, a B-band maximum at 2457,840.97 ± 0.43, a negligible host galaxy reddening where E(B − V)host ≈ 0, and a distance modulus of 30.49 ± 0.32 to the SN, corresponding to a distance of Mpc. We also present the results of two different numerical models we used for analysis in this paper: SALT2, an empirical model for Type Ia supernova optical light curves that accounts for variability components; and SNooPy, the CSP-II light-curve model that covers both optical and near-infrared wavelengths and is used for distance estimates.
