| Abstract: |
The large amount of dust observed in the early universe implies the contribution of core-collapse supernovae (CCSNe) to dust formation may be significant. Using the data obtained with Gemini, LCO, SOAR, and other ground-based telescopes, we present optical and infrared observation results of SN 2021qqu, a type IIP supernova (SN IIP) detected on June 20, 2021, with a low-luminosity galaxy WISEA J033752.00-145835.9 as its host. We employ the correlation between the luminosity, the photospheric velocity, and the color of SNe IIP to infer the distance to the host galaxy. The photometry and spectral data cover the dates from the explosion to day 400 and days 17 to 230, respectively. We present 8 sets of near-infrared spectra, which include CO emission and their temporal changes from day 150 to 230. The spectra above 2.25 microns detected CO emissions on days 157, 173, 184, and 230. Based on the [O I] and [Ca II] emission lines in the nebular phase spectrum, we estimate the initial mass of the progenitor between 12–15M⊙. |
