The multi-line slope method for the measure of the effective magnetic field of the cool stars: an application to the solar like cycle of ε Eri
C. Scalia, F. Leone, M. Gangi +2
A method for the determination of integrated longitudinal stellar fields from low-resolution spectra is the so-called slope method, which is based on the regression of the Stokes V…
A method to measure the transverse magnetic field and orient the rotational axis of stars
Francesco Leone, Cesare Scalia, Manuele Gangi +5
Direct measurements of the stellar magnetic fields are based on the splitting of spectral lines into polarized Zeeman components. With few exceptions, Zeeman signatures are hidden…
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…
