Is supernova SN 2020faa an iPTF14hls look-alike? (2021)

Keywords : supernovae general - supernovae: individual: SN 2020faa - supernovae: individual: ZTF20aatqesi - supernovae: individual: iPTF14hls

Abstract:We present observations of SN 2020faa. This Type II supernova displays a luminous lightcurve that started to rebrighten from an initial decline. We investigate this in relation to the famous supernova iPTF14hls, which received a great deal of attention and multiple interpretations in the literature, but whose nature and source of energy still remain unknown. We demonstrate the great similarity between SN 2020faa and iPTF14hls during the first 6 months, and use this comparison to forecast the evolution of SN 2020faa and to reflect on the less well observed early evolution of iPTF14hls. ...(more)
Abstract: (hide)
Photometric and spectroscopic data for SN 2020faa. Photometric data includes ZTF gri data, as well as a few epochs of Swift UVOT observations (without host subtracted). Spectra are all calibrated with r band interpolated photometry. We've also uploaded spectra to wiserep: https://wiserep.weizmann.ac.il/object/14519
