Tracing the Milky Way warp and spiral arms with classical Cepheids
B. Lemasle, H. N. Lala, V. Kovtyukh +10
Mapping the Galactic spiral structure is a difficult task since the Sun is located in the Galactic plane and because of dust extinction. For these reasons, molecular masers in radi…
Wide binary stars with non-coeval components
Oleg Malkov, Alexei Kniazev
We have estimated masses of components of visual binaries from their spectral classification. We have selected pairs, where the less massive component looks more evolved. Spectral…
The MAGIC project. III. Radial and azimuthal Galactic abundance gradients using classical Cepheids
V. Kovtyukh, B. Lemasle, G. Bono +7
Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their chem…
Wray 15-906: a candidate luminous blue variable discovered with WISE, Herschel and SALT
O. V. Maryeva, V. V. Gvaramadze, A. Y. Kniazev +1
We present the results of study of the Galactic candidate luminous blue variable Wray 15-906, revealed via detection of its infrared circumstellar shell (of \approx2 pc in diameter…
Verification of Photometric Parallaxes with Gaia DR2 Data
Oleg Malkov, Sergey Karpov, Dana Kovaleva +10
Results of comparison of Gaia DR2 parallaxes with data derived from a combined analysis of 2MASS (Two Micron All-Sky Survey), SDSS (Sloan Digital Sky Survey), GALEX (Galaxy Evoluti…
Milky Way metallicity gradient from Gaia DR2 F/1O double-mode Cepheids
Bertrand Lemasle, Gergely Hajdu, Valery Kovtyukh +8
The ratio of the first overtone (1O) / fundamental (F) periods of mixed-mode Cepheids that pulsate simultaneously in these two modes (F/1O) is metallicity-dependent. It can therefo…
