[en] Hen3-1379 is a yellow hypergiant (YHG) with evidence for episodic non-quiescent mass-loss over in last 400-1000 years in this post-red supergiant (RSG) phase of its evolution. The observational evidence suggests that though similar to the low-luminosity LBV Wray15-751, it has not yet moved to the hotter phase and is thus pre-LBV. This confirms the scenario of significant mass-loss during the RSG phase.
