Observation of a Deep Visual "Eclipse" in the WC9-Type Wolf-Rayet Star, WR 76
Rod Stubbings, Peredur Williams
TL;DR
This paper reports a rare deep eclipse in the WC9-type Wolf-Rayet star WR 76, revealing its significant dust production and suggesting it is a prolific eclipser based on observed fading events.
Contribution
It presents the observation of an unusually deep eclipse in WR 76, highlighting its potential as a prolific eclipser among Wolf-Rayet stars.
Findings
Deep 3.1 magnitude eclipse observed in 2016
WR 76 exhibits more profound eclipses than similar stars
Indications that WR 76 is a prolific eclipser
Abstract
The WC9-Type Wolf-Rayet star WR 76 is one of the most prolific dust makers identified from its infrared emission. WR 76 experienced a deep fading eclipse in 2016. The ~3.1 magnitude depth of the eclipse exceeds fadings in similar eclipses observed in WR stars thus far. Conclusions from recent and earlier analyses of eclipses observed suggests that WR 76 may be a prolific eclipser.
