Wind and nebula of the M33 variable GR290 (WR/LBV)
Olga Maryeva, Gloria Koenigsberger, Oleg Egorov +4
Context: GR290 (M33/V532=Romano's Star) is a suspected post-LBV star located in M33 galaxy that shows a rare Wolf-Rayet spectrum during its minimum light phase. In spite of many st…
GR 290 (Romano's Star): 2. Light history and evolutionary state
V. F. Polcaro, O. Maryeva, R. Nesci +11
We have built the historical light curve of the luminous variable GR 290 back to 1901, from old observations of the star found in several archival plates of M 33. These old recordi…

Daunia is a region in northern Apulia with many interesting archaeological sites, particularly of the Neolithic and Bronze Age. Beginning from the fifth millennium BC, the farmers…
The Extreme LBV Star GR290 (Romano's Star) in M33. Optical Spectrophotometric Monitoring
V. F. Polcaro, R. F. Viotti, C. Rossi +3
We study the long term, S Dor-type variability and the present hot phase of the LBV star GR290 (Romano's Star) in M33 in order to investigate possible links between the LBV and WNL…
Toward Understanding The B[e] Phenomenon: III. Properties of the optical counterpart of IRAS 00470+6429
A. S. Miroshnichenko, E. L. Chentsov, V. G. Klochkova +19
FS CMa type stars are a group of Galactic objects with the B[e] phenomenon. They exhibit strong emission-line spectra and infrared excesses, which are most likely due to recently f…
