An Empirical Effective-Temperature Calibrations for Galactic B/A Supergiants
N. L. Vaidman, A. S. Miroshnichenko, Sh. T. Nurmakhametova +9
We present empirical effective temperature Teff calibrations for Galactic supergiants of spectral types B5-A5 based on optical spectra. The relationships were derived from a refere…
Dynamical Masses and Radiative Transfer Modeling of HD 698: a Be Binary in Evolutionary Transition
Ilfa A. Gabitova, Alex C. Carciofi, Tajan H. de Amorim +13
We present a detailed analysis of the early post-mass-transfer binary HD 698 (V742 Cas) combining high-resolution optical spectroscopy, long-baseline interferometry, and radiative-…
The B[e] Phenomenon in Supergiants. A Result of Mass Transfer in Binaries, Mergers, or What?
Anatoly S. Miroshnichenko, Sergey V. Zharikov, Nadezhda L. Vaidman +1
The B[e] phenomenon discovered nearly 50 years ago features the presence of forbidden emission lines due to extended and dense circumstellar gas and large IR excesses due to the ra…
Intriguing X-ray and optical variations of the gamma Cas analog HD45314
G. Rauw, Y. Nazé, M. A. Smith +11
A growing number of Be and Oe stars, named the gamma Cas stars, are known for their unusually hard and intense X-ray emission. This emission could either trace accretion by a compa…
IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"
G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23
Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
Towards Understanding The B[e] Phenomenon: VI. Nature and Spectral Variations of HD 85567
S. A. Khokhlov, A. S. Miroshnichenko, R. Mennickent +7
We report the results of high-resolution () spectroscopic observations of the emission-line object HD 85567, which has been classified as a FS CMa type object or a p…
