On the formation of subdwarf B stars via engulfment of substellar companions
Antoine Thuillier, Lionel Siess, Valérie Van Grootel
The canonical scenario for the formation of subdwarf B (sdB) stars involves the ejection of the progenitor's envelope near the tip of the Red Giant Branch (RGB), concurrent with th…

Dust Formation in Common Envelope Binary Interactions -- III. Lightcurves
Chunliang Mu, Orsola De Marco, Luis C. Bermúdez-Bustamante +6
Luminous red novae are transient events thought to arise from common envelope binary interactions. In this paper, we perform post-processing light-curve calculations for two, 3D hy…
