Can the same generation of astronomers see both the short gamma-ray bursts and their supernovae precursors?

TL;DR

This paper explores the potential to observe sequential supernovae and gamma-ray bursts from the same stellar system, focusing on the observational challenges and possible associations like SN 1997ds and GRB 990425.

Contribution

It introduces the concept of detecting sequential SN-GRB pairs from the same progenitor system over several years, highlighting observational strategies and implications.

Findings

Possible connection between SN 1997ds and GRB 990425.

Sequential observation of supernovae and GRBs is feasible with current or future instruments.

The timing between SN and GRB can span several years, requiring long-term monitoring.

Abstract

We consider the possibility of observing supernova (SN) - gamma-ray burst (GRB) pairs separated by several years. These energetic events correspond to the second SN explosion in a double star system followed by the formation of the very short-lived pair of compact objects and finally by the GRB generation after their merge. Possible connection of SN 1997ds and GRB 990425 is discussed.
