MUSICOS 1998: Optical and X-rays Observations of Flares on the RS CVn Binary HR 1099
D. Garcia-Alvarez, B. H. Foing, D. Montes +2
We present simultaneous and continuous observations of H_alpha, H_beta, NaI D_1, D_2 and HeI D_3 lines of the chromospherically active binary HR 1099. We have observed HR 1099 for…

Beryllium, Lithium and Oxygen Abundances in F-type Stars
R. J. Garcia Lopez, M. C. Dominguez Herrera, M. R. Perez de Taoro +4
Beryllium and oxygen abundances have been derived in a sample of F-type field stars for which lithium abundances had been measured previously, with the aim of obtaining observation…
