SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss

Qian Zhai, Jujia Zhang, Xiaofeng Wang +51

We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…

Late-time evolution of the interacting stripped-envelope supernova 2017dio

C. Humina, C. P. Gutiérrez, H. Kuncarayakti +14

The discovery of stripped-envelope supernovae (SNe) interacting with dense circumstellar medium (CSM) challenges our current understanding of massive star evolution. We present lat…

SN 2018is: a low-luminosity Type IIP supernova with narrow hydrogen emission lines at early phases

R. Dastidar, K. Misra, S. Valenti +31

We present a comprehensive photometric and spectroscopic study of the Type IIP SN 2018is. The -band luminosity and the expansion velocity at 50 days post-explosion are 15.1$\…

The metamorphosis of the Type Ib SN 2019yvr: late-time interaction

Lucía Ferrari, Gastón Folatelli, Hanindyo Kuncarayakti +32

We present observational evidence of late-time interaction between the ejecta of the hydrogen-poor Type Ib supernova (SN) 2019yvr and hydrogen-rich circumstellar material (CSM), si…

SN2017egm: A Helium-rich Superluminous Supernova with Multiple Bumps in the Light Curves

Jiazheng Zhu, Ning Jiang, Subo Dong +28

When discovered, SN~2017egm was the closest (redshift ) hydrogen-poor superluminous supernova (SLSN-I) and a rare case that exploded in a massive and metal-rich galaxy. Thu…
