| Abstract: |
SN 2023ixf is one of the nearest core-collapse supernova events during the last few decades. We performed optical observations from 10 years before to 100 days after the explosion from 6 observatories in the Intensive Monitoring Survey of Nearby Galaxies program. From deep pre-explosion data, we analyze to find any significant outburst signal or precursor emission, which would have originated from the mass ejection of the red supergiant (RSG) progenitor. The multicolor light curves of SN 2023ixf are obtained, more like Type II-L, with a fast decline rate during the photospheric phase, 1.34 Vmag/50 days. Unfortunately, a significant pre-SN burst signal was not detected. Analyzing the light curve parameters of SN 2023ixf against statistical trends, it is not considered a peculiar type, though it belonged to the group with a shorter rise time. |
