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 temperature at the beginning of April gives us a hint about a physical process with a period of one month. We obtained a BV R IC time-sequence and modelled the photometric behaviour of the object. This leads us to the conclusion that the interstellar foreground extinction has to be 0.6 mag E(B − V… 
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.
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 Monocerotis
Spectroscopic observations of the peculiar variable V838 Mon during the period from the second light outburst until the fast dimming are presented. We describe high resolution (R ≈ 60 000) high S /N
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
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
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
V4332 Sgr in `Quiescence'
In 1994 V4332 Sgr underwent a mysterious eruption. Somehow its fast evolution towards a red giant star was, lacking alternative classifications, connected to the red variable M31 RV, which had its
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
A model of an expanding giant that swallowed planets for the eruption of V838 Monocerotis
ABSTRACT In early 2002 V838 Monocerotis had an extraordinary outburst whose nature isstill unclear. The optical light curve showed at least three peaks and imaging revealeda light echo around the
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
