Activity-rotation in the dM4 star Gl 729. A possible chromospheric cycle
R. V. Ibañez Bustos, A. P. Buccino, S. Messina +2
Recently, new debates about the role of layers of strong shear have emerged in stellar dynamo theory. Further information on the long-term magnetic activity of fully convective sta…
The active RS CVn-type system SZ Pictoris
C. I. Martínez, J. F. González, A. Buccino +2
We study the short and long-term variability of the spectroscopic binary SZ Pictoris, a southern RS CVn-type system. We used mid-resolution echelle spectra obtained at CASLEO spann…
HD 38858: a solar type star with a 10.8 yr activity cycle. Searching for Balmer and metallic line variations
M. Flores, J. F. González, M. Jaque Arancibia +5
Context. The detection of chromospheric activity cycles in solar-analogue and twin stars, can be used to put in context the solar cycle. However, there is a relatively low percenta…
