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 present optical, near-IR, and mid-IR spectroscopic and photometric observations of V838 Monocerotis obtained between 2008 and 2012 at the Apache Point Observatory 3.5m, NASA IRTF 3m, and Gemini South 8m telescopes. We contemporaneously analyze the optical & IR spectroscopic properties of V838 Monocerotis…

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
The Infrared Evolution of Dust in V838 Monocerotis
Luminous Red Variables are most likely eruptions that are the outcome of stellar mergers. V838 Mon is one of the best-studied members of this class, representing an archetype for stellar mergers
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
Lessons from the Onset of a Common Envelope Episode: the Remarkable M31 2015 Luminous Red Nova Outburst
This paper investigates the recent stellar merger transient M31LRN 2015 in the Andromeda galaxy. We analyze published optical photometry and spectroscopy along with a Hubble Space Telescope detection
Evolution of the dust in V4332 Sagittarii
An eruptive nova-like event took place in 1994 in the stellar-merger candidate V4332 Sgr. Following the eruption, dust consisting of refractory silicate rich dust grains containing a significant
Massive star mergers and the recent transient in NGC 4490: a more massive cousin of V838 Mon and V1309 Sco
Some of the data reported here were obtained at the MMT Observatory, a joint facility of the University of Arizona and the Smithsonian Institution. We thank the staffs at Lick and MMT Observatories
The Milky Way in SDSS and in N-body Models
TLDR
A comparison between recent Sloan Digital Sky Survey Galactic studies and N–body simulations to aid in the interpretation of observed structural features is presented and demonstrates the emergent and informative value of direct comparison between the two.
One of Everything: The Breakthrough Listen Exotica Catalog
We present Breakthrough Listen’s Exotica Catalog as the centerpiece of our efforts to expand the diversity of targets surveyed in the Search for Extraterrestrial Intelligence (SETI). As motivation,

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.

We report photometry and spectroscopy of the evolution of Nova Sagittarii 1994 1 (V4332 Sagittarii) during outburst. We compare the photometric and spectral evolution of this outburst with known
Infrared spectroscopy of carbon monoxide in V838 Monocerotis during 2002–2006
Aims. We report spectra of the overtone and fundamental bands of CO in the eruptive variable V838 Mon, which trace the recent evolution of the star and allow its ejecta to be characterized. Methods.
Nova Monocerotis 2002 (V838 Mon) at early outburst stages
AbstractWe obtained U BV R photometric and spectroscopic observations during the outburst of V838 Mon. Before its outburst, the B brightness of the star had been stable ( $$\tilde15.^m 85$$ ) for 45
An unusually brilliant transient in the galaxy M85
TLDR
The discovery of an optical transient in the outskirts of the lenticular galaxy Messier 85 in the Virgo cluster is reported, distinctly brighter than novae, but fainter than type Ia supernovae (which is expected in a population of old stars in lenticular galaxies).
