New, late-type spectroscopic binaries with X-ray emission
A. Frasca, G. Catanzaro, I. Busà +6
In this paper we present a spectroscopic study of six double-lined binaries, five of which were recently discovered in a high-resolution spectroscopic survey of optical counterpart…
Gaia Data Release 3. Stellar chromospheric activity and mass accretion from Ca II IRT observed by the Radial Velocity Spectrometer
A. C. Lanzafame, E. Brugaletta, Y. Frémat +82
The Gaia Radial Velocity Spectrometer provides the unique opportunity of a spectroscopic analysis of millions of stars at medium-resolution in the near-infrared. This wavelength ra…
Estimating the chromospheric magnetic field from a revised NLTE modeling: the case of HR7428
Innocenza Busa, Giovanni Catanzaro, Antonio Frasca +6
In this work we use the semi-empirical atmospheric modeling method to obtain the chro-mospheric temperature, pressure, density and magnetic field distribution versus height in the…
Interpreting the spectral behavior of MWC 314
A. Frasca, A. S. Miroshnichenko, C. Rossi +4
MWC 314 is one of the most luminous stars in the Milky Way. Its fundamental parameters are similar to those of LBVs, although no large photometric variations have been recorded. We…
CAOS spectroscopy of Am stars Kepler targets
G. Catanzaro, V. Ripepi, K. Biazzo +6
The {\it Kepler} space mission and its {\it K2} extension provide photometric time series data with unprecedented accuracy. These data challenge our current understanding of the me…
