The spectroscopic binary system Gl 375. I. Orbital parameters and chromospheric activity
Rodrigo F. Díaz, Jorge F. González, Carolina Cincunegui +1
We study the spectroscopic binary system Gl 375. We employ medium resolution echelle spectra obtained at the 2.15 m telescope at the Argentinian observatory CASLEO and photometric…
The Na I D resonance lines in main sequence late-type stars
Rodrigo F. Díaz, Carolina Cincunegui, Pablo J. D. Mauas
We study the sodium D lines (D1: 5895.92 Å; D2: 5889.95 Å) in late-type dwarf stars. The stars have spectral types between F6 and M5.5 (B-V between 0.457 and 1.807) and metallicity…
A possible activity cycle in Proxima Centauri
Carolina Cincunegui, Rodrigo F. Díaz, Pablo J. D. Mauas
Several late-type stars present activity cycles resembling the Solar one. This fact has been observed mostly in stars ranging from F to K, i.e., in stars with a radiative core and…
