  author={Romuald Tylenda and Tomasz Kamiński},
  journal={Astronomy and Astrophysics},
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 obtaining estimates of the optical thickness of the circumstellar matter in front of V838 Mon, as well as optical properties of dust grains in the echoing medium. In particular, we are interested in studying whether the echoing medium can be responsible for the observed faintness of the B-type…

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

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

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


The eruptive variable V838 Monocerotis (V838 Mon) gained notoriety in 2002 when it brightened nine magnitudes in a series of three outbursts and then rapidly evolved into an extremely cool

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

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

The long-period Galactic Cepheid RS Puppis - III. A geometric distance from HST polarimetric imaging of its light echoes

As one of the most luminous Cepheids in the Milky Way, the 41.5-day RS Puppis is an analog of the long-period Cepheids used to measure extragalactic distances. An accurate distance to this star would



On the light echo in V838 Mon

We present a theoretical outline of the light echo phenomenon and results of simple numerical simulations and we study the available images of the light echo in V838 Mon obtained with HST. An

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

Spitzer Observations of V838 Monocerotis: Detection of a Rare Infrared Light Echo

We present Spitzer observations of the unusual variable V838 Monocerotis. Extended emission is detected around the object at 24, 70, and 160 μm. The extended infrared emission is strongly correlated


Following the outburst of the unusual variable star V838 Monocerotis in 2002, a spectacular light echo appeared. A light echo provides the possibility of direct geometric distance determination,

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


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

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

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

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
