We discuss various models and scenarios proposed to explain the nature of the V838 Mon type eruptions. In this class of eruptive objects we include: M 31 RV (erupted in 1988), V4332 Sgr (erupted in 1994) and V838 Mon (erupted in 2002). We concentrate on three models: ( i ) thermonuclear runaway on an accreting white dwarf (nova-like event); ( ii ) He-shell flash in a post asymptotic giant branch star (born-again AGB); and ( iii ) merger of stars. We show that models ( i ) and ( ii ) cannot…

V4332 Sagittarii: A circumstellar disc obscuring the main object
V4332 Sgr experienced an outburst in 1994 whose observational characteristics in many respects resemble those of the eruption of V838 Mon in 2002. It has been proposed that these objects erupted
High-resolution optical spectroscopy of V838 Monocerotis in 2009
Context. V838 Mon erupted at the beginning of 2002. In the course of the outburst the object evolved to low effective temperatures and declined as a very late M-type supergiant. Among various
The Infrared Evolution of Dust in V838 Monocerotis
Luminous Red Variables are most likely eruptions that are the outcome of stellar mergers. V838 Mon is one of the best-studied members of this class, representing an archetype for stellar mergers
Evolution of the stellar-merger red nova V1309 Scorpii: SED analysis
One very important object for understanding the nature of red novae is V1309 Sco. Its pre-outburst observations showed that, before its red-nova eruption in 2008, it was a contact binary quickly
The planets capture model of V838 Monocerotis: conclusions for the penetration depth of the planet(s)
V838 Mon is the prototype of a new class of objects. Understanding the nature of its multistage outburst and similar systems is challenging. So far, several scenarios have been invoked to explain
KECK/HIRES SPECTROSCOPY OF V838 MONOCEROTIS IN OCTOBER 2005
V838 Monocerotis (V838 Mon) erupted at the beginning of 2002 becoming an extremely luminous star with L ≃ 106L☉. Among various scenarios proposed to explain the nature of the outburst, the most
V1309 Scorpii: merger of a contact binary
Context. Stellar mergers are expected to take place in numerous circumstences in the evolution of stellar systems. In particular, they are considered as a plausible origin of stellar eruptions of the
An analysis of a spectrum of V838 Monocerotis in October 2005
Context. V838 Mon erupted at the beginning of 2002 becoming an extremely luminous star with $L=10^6~L_{\sun}$. Among various scenarios proposed to explain the nature of the outburst, the most
NGC 300 OT2008-1 AS A SCALED-DOWN VERSION OF THE ETA CARINAE GREAT ERUPTION
We propose that the intermediate luminosity optical transient NGC 300 OT2008-1 was powered by a mass transfer episode from an extreme asymptotic giant branch star to a main sequence (MS) companion.
Post-outburst spectra of a stellar-merger remnant of V1309 Scorpii: from a twin of V838 Monocerotis to a clone of V4332 Sagittarii
We present optical and infrared spectroscopy of V1309 Sco, an object that erupted in 2008 in a stellar-merger event. During the outburst, V1309 Sco displayed characteristics typical of red
