X-ray reprocessing in accreting pulsar GX 301-2 observed with Insight-HXMT

L. Ji, V. Doroshenko, V. Suleimanov +100

We investigate the absorption and emission features in observations of GX 301-2 detected with Insight-HXMT/LE in 2017-2019. At different orbital phases, we found prominent Fe Kalph…

A unified accreting magnetar model for long-duration gamma-ray bursts and some stripped-envelope supernovae

W. L. Lin, X. F. Wang, L. J. Wang +1

Both the long-duration gamma-ray bursts (LGRBs) and the Type I superluminous supernovae (SLSNe~I) have been proposed to be primarily powered by central magnetars. A correlation, pr…

The Exotic Type Ic Broad-Lined Supernova SN 2018gep: Blurring the Line Between Supernovae and Fast Optical Transients

T. A. Pritchard, Katarzyna Bensch, Maryam Modjaz +28

In the last decade a number of rapidly evolving transients have been discovered that are not easily explained by traditional supernovae models. We present optical and UV data on on…

Optical and spectral observations and hydrodynamic modelling of Type IIb Supernova 2017gpn

Elena A. Balakina, Maria V. Pruzhinskaya, Alexander S. Moskvitin +6

In this work we present the photometric and spectroscopic observations of Type IIb Supernova 2017gpn. This supernova was discovered in the error-box of LIGO/Virgo G299232 gravitati…

SN 2018zd: An Unusual Stellar Explosion as Part of the Diverse Type II Supernova Landscape

Jujia Zhang, Xiaofeng Wang, Jozsef Vinko +29

We present extensive observations of SN 2018zd covering the first \,d after the explosion. This SN shows a possible shock-breakout signal \,hr after the explosion…

SN 2019ehk: A Double-Peaked Ca-rich Transient with Luminous X-ray Emission and Shock-Ionized Spectral Features

Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +64

We present panchromatic observations and modeling of the Calcium-rich supernova 2019ehk in the star-forming galaxy M100 (d16.2 Mpc) starting 10 hours after explosion and c…
