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…

SN 2019vxm: A luminous and long-lived Type IIn supernova with early flash-ionisation features

Y. -Z. Cai, A. Pastorello, T. J. Moriya +38

We present the photometric and spectroscopic analysis of the luminous and long-lasting Type IIn supernova (SN) 2019vxm. The SN reaches a peak V-band absolute magnitude of MV = -20.…

SN 2017ati: A luminous type IIb explosion from a massive progenitor

Z. -H. Peng, S. Benetti, Y. -Z. Cai +21

We present optical photometric and spectroscopic observations of the Type~IIb supernova (SN)~2017ati. It reached the maximum light at about 27~d after the explosion and the light c…
