MAGIC Collaboration: E. Aliu, et al
TL;DR
This paper establishes the first observational limits on high-energy gamma-ray emission from isolated Wolf-Rayet binary systems using MAGIC telescope data, advancing understanding of stellar wind interactions.
Contribution
It provides the first bounds on gamma-ray emission from WR binaries, a key step in testing theoretical models of high-energy processes in such systems.
Findings
No significant gamma-ray emission detected
Set upper limits on gamma-ray flux from WR 147 and WR 146
Supports constraints on theoretical emission models
Abstract
High-energy gamma-ray emission is theoretically expected to arise in tight binary star systems (with high mass loss and high velocity winds), although the evidence of this relationship has proven to be elusive so far. Here we present the first bounds on this putative emission from isolated Wolf-Rayet (WR) star binaries, WR 147 and WR 146, obtained from observations with the MAGIC telescope.
