  journal={Astronomy and Astrophysics},
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 scenarios proposed to explain the nature of the outburst, the most promising is a stellar merger event. Aims. We aim at studying the structure and evolution of the object in the decline from the 2002 eruption. Methods. We obtained spectroscopic observations of V838 Mon in January−March 2009 with UVES/VLT…

The continued optical to mid-IR evolution of V838 Monocerotis
The eruptive variable V838 Monocerotis gained notoriety in 2002 when it brightened nine magnitudes in a series of three outbursts and then rapidly evolved into an extremely cool supergiant. We
Progenitor and Remnant of the Luminous Red Nova V838 Monocerotis
Abstract —The article presents the results of multicolor photometry, medium and low resolution spectroscopy of the red nova V838 Mon remnant for 16 years after the 2002 outburst. We also used the
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
Light echo of V838 Monocerotis: properties of the echoing medium ⋆
Context. The light echo phenomenon that accompanied the 2002 eruption of V838 Mon allows one to study the properties of the diffuse dusty matter in the vicinity of the object. Aims. We are aiming at
CK Vul: evolving nebula and three curious background stars
We analyse the remnants of CK Vul (Nova Vul 1670) using optical imaging and spectroscopy. The imaging, obtained between 1991 and 2010, spans 5.6% of the life-time of the nebula. The flux of the
On the properties of dust and gas in the environs of V838 Monocerotis
Herschel FIR imaging and spectroscopy were taken at several epochs to probe the central point source and the extended environment of V838 Mon. PACS and SPIRE maps were used to obtain photometry of
SiO maser astrometry of the red transient V838 Monocerotis
We present multiepoch observations with the Very Long Baseline Array of SiO maser emission in the v = 1, J = 1−0 transition at 43 GHz from the remnant of the red nova V838 Mon. We modeled the
We propose that the energetic major outburst of the supernova (SN) impostor SN 2009ip in 2012 September (outburst 2012b) was a mergerburst event, where two massive stars merged. The previous
Aluminium oxide in the optical spectrum of VY Canis Majoris
We report the first identification of the optical bands of the B 2 Σ + –X 2 Σ + system of AlO in the red supergiant VY CMa. In addition to TiO, VO, ScO, and YO, which were recognized in the optical
OGLE-2002-BLG-360: from a gravitational microlensing candidate to an overlooked red transient
OGLE-2002-BLG-360 was discovered as a microlensing candidate by the OGLE-III project. The subsequent light curve however clearly showed that the brightening of the object could not have resulted from


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 106 L ☉. Among various scenarios proposed to explain the nature of the outburst, the most
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
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
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 post-outburst photometric behaviour of V838 Mon
The unusual eruptive variable discovered in Monoceros in 2002 January underwent dramatic photometric and spectroscopic changes in the months prior to its 2002 June‐August conjunction with the Sun.
