Red novae are transients powered by collisions of non-compact stars. Among their progenitors are systems of evolved subgiants and giants stars. Remnants of such red novae display bipolar structures which have remarkably close characteristics to many post-AGB or pre-PN systems. It is important to ask (and eventually verify) whether some of the less-known post-main-sequence objects (mis-)classified as pre-PNe can be merger remnants similar to the red nova remnants.

  1. Mass-feeding of jet-launching white dwarfs in grazing and common envelope evolution

    astro-ph.SR 2025-05 conditional novelty 7.0 of 10

    White dwarfs entering a giant's envelope may grow a one-solar-radius accretion disk that launches jets powered by gravitational energy, explaining jet-shaped planetary nebulae and luminous red novae.

  2. Constraining the physical structure of the circumstellar environment of V838 Monocerotis remnant

    astro-ph.SR 2025-06 conditional novelty 5.0 of 10

    A torus, jets, and inner ellipsoid model reproduces most H-band interferometry and low polarization of V838 Mon, but leaves the K-band closure phases unexplained.
