Star-Planet Interaction at radio wavelengths in YZ Ceti: Inferring planetary magnetic field
Corrado Trigilio, Ayan Biswas, Paolo Leto +13
In exoplanetary systems, the interaction between the central star and the planet can trigger Auroral Radio Emission (ARE), due to the Electron Cyclotron Maser mechanism. The high b…
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…
Spectroscopy of the hot pulsating star Beta Cephei. Velocities and EWs from C,N,O and Si lines
G. Catanzaro, F. Leone, I. Busa' +1
Frequencies in oscillating Cephei stars are usually inferred by means of radial velocities measured from the SiIII triplet 4552-4574 A. These lines, relatively insensitive to t…
