The photometric evolution of M 31-RV has been investigated on 1447 plates of the Andromeda galaxy obtained over half a century with the Asiago telescopes. M 31-RV is a gigantic stellar explosion that occurred during 1988 in the Bulge of M 31 and that was characterized by the appearance for a few months of an M supergiant reaching Mbol = −10. The 1988 outburst has been positively detected on Asiago plates, and it has been the only such event recorded over the period covered by the plates (1942…

Hubble Space Telescope Imaging of the Outburst Site of M31?RV*
M31 RV is a luminous red variable star that appeared for several months in the bulge of M31 during 1988. Unlike classical novae, M31 RV was cool throughout its outburst. Interest in this object has
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
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
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,
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
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
Identification of the Long-Sought Common-Envelope Events
The natural range of time scales and energies from this model, as well as the expected colors, light-curve shapes, ejection velocities, and event rate, match those of a recently recognized class of red transient outbursts.
M31-RV was an extraordinarily luminous ({approx}10{sup 6} L{sub sun}) eruptive variable, displaying very cool temperatures (roughly 1000 K) as it faded. While this object's peak luminosity matched or
V1309 Sco—Understanding a Merger
One of the two outcomes of a common envelope (CE) event is a merger of the two stars. To date, the best known case of a binary merger is the V1309 Sco outburst, where the orbital period was known and
Infall and SiO emission in V838 Mon
ABSTRACT We present moderate and high resolution infrared spectroscopyof the peculiar eruptivevariable V838 Mon, which underwent a series of remarkable outbursts in early 2002.During the period


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 mysterious eruption of V838 Mon
V838 Mon is marking one of the most mysterious stellar outbursts on record. The spectral energy distribution of the progenitor resembles an under-luminous F main sequence star (at V =1 5:6 mag), that
Nova Sagittarii 1994 1 (V4332 Sagittarii): The Discovery and Evolution of an Unusual Luminous Red Variable Star
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
An energetic stellar outburst accompanied by circumstellar light echoes
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.
A search for novae in M 31 globular clusters.
By combining a local sky-fitting algorithm with a Fourier point-spread-function matching technique, nova outbursts have been searched for inside 54 of the globular clusters contained on the Ciardullo
Identification of 13 Cepheids and 333 other variables in M 31
We present Cousins R and I band photometry of variable stars in a ${\sim}13'\times 13'$ region in the disk of M 31 galaxy, obtained during 141 nights. Of the 26 Cepheid variables present in the
The Brightest Asymptotic Giant Branch Stars in the Inner Bulge of M31

The spectroscopic and photometric evolution of novae in the bulge of M31
Results are presented from a 3 year (1987-1989) spectroscopic and photometric survey of novae in M31's bulge, the first comprehensive study of novae outside the Galactic and Magellanic Cloud systems.
Main-Sequence Stellar Eruption Model for V838 Monocerotis
We propose that the energy source of the outburst of V838 Mon and similar objects is an accretion event, i.e., gravitational energy rather than thermonuclear runaway. We show that the merger of two
Rare thermonuclear explosions in short-period cataclysmic variables, with possible application to the nova-like red variable in the Galaxy M31
A very bright nova with a peak luminosity significantly larger than the relevant Eddington luminosity might be initiated by a hydrogen shell flash on a very cold low-mass degenerate dwarf accreting
