We report high spatial resolution 11.2 and 18.1 μm imaging of V838 Monocerotis obtained with Gemini Observatory's Michelle instrument in 2007 March. Strong emission is observed from the unresolved stellar core of V838 Mon in our Gemini imagery and is confirmed by Spitzer MIPS 24 μm imaging obtained in 2007 April. The 2007 flux density of the unresolved mid-infrared emission component is ~2 times brighter than that observed in 2004. No clear change in the net amount of 24 μm extended emission is…

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
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 dusty aftermath of SN Hunt 248: merger-burst remnant?
SN Hunt 248 was classified as a non-terminal eruption (a supernova ‘impostor’) from a directly identified and highly variable cool hypergiant star. The 2014 outburst achieved peak luminosity
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
Luminous red novae: Stellar mergers or giant eruptions?
We present extensive datasets for a class of intermediate-luminosity optical transients known as luminous red novae. They show double-peaked light curves, with an initial rapid luminosity rise to a
A binary merger origin for inflated hot Jupiter planets
We hypothesize that hot Jupiters with inflated sizes represent a separate planet formation channel, the merging of two low-mass stars. We show that the abundance and properties of W UMa stars and low
Assessment of laser-induced thermal load on silicon nanostructures based on ion desorption yields
Experimental assessment of the thermal load induced by fast laser pulses on micro- and nanostructures through IR imaging is currently too slow and lacks the spatial resolution to be useful. In this

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
Evolution of the Inner Circumstellar Envelope of V838 Monocerotis
We present imaging polarimetry observations of the eruptive variable V838 Monocerotis and its neighboring field obtained in 2002 October. The polarization of field stars confirms the previously
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
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 energetic stellar outburst accompanied by circumstellar light echoes
TLDR
High-resolution imaging and polarimetry of light echoes indicate that V838 Mon represents a hitherto unknown type of stellar outburst, for which the authors have no completely satisfactory physical explanation.

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,
Interferometric Observations of V838 Monocerotis
We have used long-baseline near-IR interferometry to resolve the peculiar eruptive variable star V838 Mon and to provide the first direct measurement of its angular size. Assuming a uniform disk

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
0.8-13 MICRON SPECTROSCOPY OF V838 MONOCEROTIS AND A MODEL FOR ITS EMISSION
Abstract : We report on the results of a number of infrared spectra (0.8-2.5, 2.1-4.6, and 3-14 microns) of V838 Monocerotis, taken from a short time after discovery in 2002 January to about 14
