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 archival photometry with the photographic plates of the Sonneberg and Moscow collections from 1928 to 1994. Analysis of these observational data confirmed that the progenitor of the V838 Mon explosion was a wide pair of B3V type stars of reduced luminosity. A brighter component exploded; it was 36 per…

We present the results of the study of the red nova PSN J140216 78+5426205 based on the observations carried out with the Russian 6-m telesco pe (BTA) along with other telescopes of SAO RAS and SAI
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
Comparative spectral analysis of the peculiar red novae V838 Mon and V4332 Sgr in quiescence after their outbursts
We analyze spectra of V838 Mon and V4332 Sgr taken in 2004–2005 using the 6 m telescope of the Special Astrophysical Observatory with the UAGS and SCORPIO spectrographs; the spectra have a resolution
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
On the distance, reddening and progenitor of V838 Mon
Extensive optical and infrared photometry as well as low and high resolution spectroscopy are used as inputs in deriving robust estimates of the reddening, distance and nature of the progenitor of
Photometry and spectroscopy of the luminous red nova PSNJ14021678+5426205 in the galaxy M101
We present the results of the study of a red nova from the observations carried out with the Russian 6-m telescope (BTA) along with other telescopes of SAO RAS and SAI MSU. To investigate the nova
A Young Stellar Cluster Surrounding the Peculiar Eruptive Variable V838 Monocerotis
V838 Monocerotis is an unusual variable star that underwent a sudden outburst in 2002. Unlike a classical nova, which quickly evolves to high temperatures, V838 Mon remained an extremely cool,
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
Eclipse of the B3V companion and flaring of emission lines in V838 Monocerotis
After four years during which only the spectacular light echo was showing continuous and rapid evolution while the central star was nearly constant, in autumn 2006 V838 Mon began a sequence of events
