Chromospheric models of solar analogues with different activity levels
(EDP Sciences, 2005-12)
We computed chromospheric models of the Sun as a star and of nine solar analogues. The atmospheric models were constructed to obtain the best possible match with the Ca II K and Hβ lines, including the asymmetry of the ...
Chromospheric activities and kinematics for solar type dwarfs and subgiants: analysis of the activity distribution and the AVR
(2011)
In this work we present chromospheric activity indices, kinematics, radial-velocities and rotational velocities for more than 850 FGK-type dwarfs and subgiant stars in the southern hemisphere and test how best to calibrate ...
Chromospheric activity of stars with planets
(Astronomy & Astrophysics, 2011)
Long-term chromospheric activity of non-eclipsing RS CVn-type stars chromospheric activity of non-eclipsing RS CVn-type stars
(EDP Sciences, 2009-12)
Context: The IUE database provides a large number of UV high and low-resolution spectra of RS CVn-type stars from 1978 to 1996. In particular, many of these stars were monitored continuously during several seasons by ...
Chromospheric Models of Solar Type Stars: The Vaughan-Preston Gap
(Springer, 2004-12)
We have built different models for stars of the same spectral type than the Sun but with different levels of chromospheric activity, to study the response of the S index of activity built from the emission of the Ca II ...
