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 V838 Mon type. V 1309 Sco is the most recent eruption of this type in our Galaxy. The object was discovered in September 2008. Aims. Our aim is to investigate the nature of V 1309 Sco. Methods. V 1309 Sco has been photometrically observed in course of the OGLE project since August 2001. We analyse…

V1309 Sco—Understanding a Merger
One of the two outcomes of a common envelope (CE) event is a merger of the two stars. To date, the best known case of a binary merger is the V1309 Sco outburst, where the orbital period was known and
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
Evolution of the progenitor binary of V1309 Scorpii before merger
It was recently demonstrated that the eruption of V1309 Sco was a result of a merger of the components of a cool contact binary. We computed a set of evolutionary models of the detached binaries with
The asymptotic evolution of the stellar merger V1309 Sco: a Blue Straggler in the making?
Stellar mergers are estimated to be common events in the Galaxy. The best studied stellar merger case to date is V1309 Sco (= Nova Scorpii 2008) which was originally misclassified as a Nova event.
A low-mass-ratio and deep contact binary as the progenitor of the merger V1309 Sco
Nova Sco 2008 (=V1309 Sco) is an example of a V838 Mon type eruption rather than a typical classical nova. This enigmatic object was recently shown to have resulted from the merger of two stars in a
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
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
Evolution of red Nova V4332 Sagittarii remnant
We present the multicolor BV RI photometry and BTA/SCORPIO spectroscopy for the red nova V4332 Sgr, performed in 2005–2012. We have analyzed the behavior of the nova remnant, considering our
MY Camelopardalis, a very massive merger progenitor
Context. The early-type binary MY Cam belongs to the young open cluster Alicante 1, embedded in Cam OB3. Aims. MY Cam consists of two early-O type main-sequence stars and shows a photometric
The dusty aftermath of the V1309 Sco binary merger
We present mid-IR photometry and spectra of the merged binary V1309 Sco taken between 18 and 23 months after outburst. Strong mid-IR emission and a solid state absorption feature indicate the


V4332 Sagittarii revisited
The eruption of V4332 Sgr discovered in February 1994 shows striking similarities to that of V838 Mon started in January 2002. The nature of these eruptions is, however, enigmatic and unclear. We
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
Eruptions of the V838 Mon type: stellar merger versus nuclear outburst models
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
Evolution of V838 Monocerotis during and after the 2002 eruption
By fitting the available photometric data on V838 Mon with standard supergiant spectra we have derived principal stellar parameters, i.e. effective temperature, radius and luminosity, and followed
The mysterious eruption of V838 Mon
V838 Mon is marking one of the most mysterious stellar outbursts on record. The spectral energy distribution of the progenitor resembles an under-luminous F main sequence star (at V =1 5:6 mag), that
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.
Eclipsing Binaries in the OGLE Variable Star Catalog. III. Long-Period Contact Systems
A sample of contact binaries discovered by the OGLE project in Baade's window, with orbital periods longer than 1 day and with available color and light-curve data, has been analyzed. It consists of
Strong linear polarization of V4332 Sagittarii: a dusty disc geometry
The eruption of V4332 Sgr was observed in 1994. During the outburst, the object became extremely red, so it is considered as belonging to luminous red transients of the V838 Mon type. It has recently
An energetic stellar outburst accompanied by circumstellar light echoes
High-resolution imaging and polarimetry of light echoes indicate that V838 Mon represents a hitherto unknown type of stellar outburst, for which the authors have no completely satisfactory physical explanation.
Nova Sagittarii 1994 1 (V4332 Sagittarii): The Discovery and Evolution of an Unusual Luminous Red Variable Star
We report photometry and spectroscopy of the evolution of Nova Sagittarii 1994 1 (V4332 Sagittarii) during outburst. We compare the photometric and spectral evolution of this outburst with known
