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 promising is a stellar merger event. Aims. We attempt to obtain information about the structure and evolution of the object in the decline from the 2002 eruption. Methods. The results of spectroscopic observations of the object obtained in October 2005 with the Keck/HIRES instrument, presented in detail in…

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
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
V838 Monocerotis: the central star and its environment a decade after outburst
Aims. V838 Monocerotis erupted in 2002, brightened in a series of outbursts, and eventually developed a spectacular light echo. A very red star emerged a few months after the outburst. The whole
A molecular cloud within the light echo of V838 Monocerotis
Context. V838 Mon is an eruptive variable, which exploded in 2002. It displayed the most spectacular light echo ever observed. However, neither the origin of the reflecting matter nor the nature of
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
XMM-Newton Detection of a Transient X-ray Source in the Vicinity of V838 Monocerotis
We report the XMM-Newton/EPIC detection in 2008 March of a luminous (LX ~ 1032-33 erg s–1), variable X-ray source in the vicinity (within ~6'') of the enigmatic star V838 Mon, which underwent a
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
Submillimeter-wave emission of three Galactic red novae: cool molecular outflows produced by stellar mergers
Red novae are optical transients erupting at luminosities typically higher than those of classical novae. Their outbursts are believed to be caused by stellar mergers. We present
Binary Red Supergiants. II. Discovering and Characterizing B-type Companions
The percentage of massive main sequence OB stars in binary systems is thought to be as high as 100%. However, very few Galactic binary red supergiants (RSGs) have been identified, despite the fact


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
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 peculiar variable V838 Mon
V838 Mon underwent, after a first nova-like outburst in January and a usual decline, a second outburst after one month, and a third weak one again a month later. Moreover, a very small increase of
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.
On the progenitor of V838 Monocerotis
We summarize and analyze the available observational data on the progenitor and the environment of V838 Mon. From the available photometric data for the progenitor of V838 Mon we exclude the
Extended CO emission in the field of the light echo of V838 Monocerotis
