Wolf-Rayet star clusters show a marginal spatial correlation with unidentified GeV gamma-ray sources, with 11 new cluster associations and 4 isolated WR stars identified as potential emitters from wind termination shocks.

A one-zone model fitted to radio observations of WR 102's bubble predicts that protons accelerated at the wind shock dominate high-energy emission but produce an undetectable gamma-ray flux.
NEOWISE-R data identifies ten new non-variable dust makers among WC stars (including three early subtypes), six new episodic dust makers, and revises the dust formation period of HD 36402 to 5.1 years.
Non-LTE wind atmosphere models computed with CMFGEN reproduce the SED and Balmer decrement of most Little Red Dots when dust-attenuated with Av ~2, while predicting Fe II, O I, and Ca lines, but struggle to produce both a genuine Balmer break and strong lines simultaneously.

High-energy Processes in the Bubbles of Wolf-Rayet Stars: The case of WR 102
A one-zone model fitted to radio observations of WR 102's bubble predicts that protons accelerated at the wind shock dominate high-energy emission but produce an undetectable gamma-ray flux.
