V838 Mon: A slow waking up of Sleeping Beauty?
T. Liimets, I. Kolka, M. Kraus +15
Context. V838 Monocerotis is a peculiar binary that underwent an immense stellar explosion in 2002, leaving behind an expanding cool supergiant and a hot B3V companion. Five years…
AGB candidates in the field of gamma Cas
Roberto Nesci, Taavi Tuvikene, Corinne Rossi +5
We report the spectroscopic and photometric monitoring of a sample of 530 candidate AGB stars in a 5 degrees field, selected from the IPHAS catalog: historic light curves were deri…
Variability survey of brightest stars in selected OB associations
Jaan Laur, Indrek Kolka, Tõnis Eenmäe +2
The stellar evolution theory of massive stars remains uncalibrated with high-precision photometric observational data mainly due to a small number of luminous stars that are monito…
Sonneberg plate photometry for Boyajian's Star in two passbands
Michael Hippke, Peter Kroll, Frank Matthei +10
The F3 main sequence star KIC 8462852 (Boyajian's Star) showed deep (up to 20%) day-long brightness dips of unknown cause during the 4 years of the Kepler mission. A 0.164 mag (16%…
Period change of massive binaries from combined photometric and spectroscopic data in Cygnus OB2
Jaan Laur, Elmo Tempel, Taavi Tuvikene +2
Context. Mass loss is an important property in evolution models of massive stars. As up to 90% of the massive stars have a visual or spectroscopic companion and many of them exhibi…
