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 positions of maser spots to derive a parallax of 0.166 ± 0.060 mas. Combining this parallax with other distance information results in a distance of 5.6 ± 0.5 kpc, which is in agreement with an independent geometric distance of 6.1 ± 0.6 kpc from modeling polarimetry images of V838 Mon’s light echo…

Study of the Galactic Rotation Based on Masers and Radio Stars with VLBI Measurements of Their Parallaxes
Based on published data, we have produced a sample of 256 radio sources whose trigonometric parallaxes and proper motions were measured by VLBI. This sample contains Galactic masers associated with
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
Molecular remnant of Nova 1670 (CK Vulpeculae)
CK Vul is the remnant of an energetic eruption known as Nova 1670 that is thought to be caused by a stellar merger. The remnant is composed of (1) a large hourglass nebula of recombining gas (of

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
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
VLBA SiO observations of bright O-rich AGB stars
We present the results of observations of the SiO masers at 7 mm wavelength in several oxygen rich Asymptotic Giant Branch (AGB) stars. These observations were coordinated with observations using the
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
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
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,
