Possible detection of π0-decay γ-ray emission from Cyg OB2 by EGRET.

CHEN W., WHITE R.L. and BERTSCH D.

Abstract (from CDS):

We report possible detection of π0-decay radiation from Cyg OB2, a nearby (1.7kpc) massive OB star association. The EGRET flux (>100MeV) maps clearly indicate a point source whose error circle includes both Cyg OB2 and Cyg X-3. We show that Cyg X-3 is unlikely to be the counterpart for the EGRET source, because of the marginal spatial consistency and the lack of the 4.8-hour modulation seen in other high energy emissions from Cyg X-3. If confirmed, this will be the first detection by EGRET of massive stars.
