Asymmetrical nebula of the M33 variable GR290 (WR/LBV)
Olga V. Maryeva, Gloria Koenigsberger, Sergey V. Karpov +5
Context: GR290 (M33 V0532=Romano's star) is a luminous M33 object undergoing photometric variability typical for luminous blue variable (LBV) stars. It lies inside Wolf-Rayet regio…
The History Goes On: Century Long Study of Romano's Star
Olga Maryeva, Roberto F. Viotti, Gloria Koenigsberger +3
GR 290 (M 33 V0532 = Romano's Star) is a unique variable star in the M33 galaxy, which simultaneously displays variability typical for luminous blue variable (LBV) stars and physic…
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…
Investigation of faint galactic carbon stars from the first Byurakan spectral survey. III. Infrared characteristics
K. S. Gigoyan, A. Sarkissian, C. Rossi +5
Infra-Red(IR) astronomical databases, namely, IRAS, 2MASS, WISE, and Spitzer, are used to analyze photometric data of 126 carbon stars whose spectra are visible in the First Byurak…
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…
