Source Group: LiONS
Keywords: Supernova
Abstract:
LJT spectroscopic classification of SN 2023erk and SN 2023epj as young type Ia supernovae
We report the spectroscopic classification of the following transients with the spectra obtained by the Lijiang 2.4-m telescope (LJT +YFOSC) at the Lijiang Observatory of Yunnan Observatories.
SN | Obs. date | type | phase | redshift
SN 2023epj | 2023-04-08 19:50:15| Ia | -3 to -9d* | 0.0267
SN 2023erk | 2023-04-09 12:41:37 | Ia | -7 to -10 d* | 0.066
*via SNID and GELTO.
