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…
MUSICOS 1998: Observations of Rotational Modulation and 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, HeI D_3 and CaII H & K lines of the chromospherically active binary HR 1099. We have observed…
Multiwavelength optical observations of the chromospherically active binary system OU Gem
A. Latorre, D. Montes, M. J. Fernandez-Figueroa
We have analysed several multiwavelength optical observations (H_alpha, H_beta, H_epsilon, Ca II H & K, Ca II IRT lines) of chromospherically active binary system OU Gem, taken in…
Chromospheric activity of the double-lined spectroscopic binary BF Lyn
D. Montes, R. Lachaume, M. J. Fernandez-Figueroa
We present simultaneous spectroscopic observations taken during four observing runs (1996 to 1999) of H_alpha, H_beta, H_epsilon, Ca II H & K, and Ca II IRT lines of the chromosphe…
Li I enhancement during a long-duration stellar flare
David Montes, Lawrence W. Ramsey
We report the possible detection of a Li I 6708 AA line enhancement during an unusual long-duration optical flare in the recently discovered, X-ray/EUV selected, chromospherically…
Multiwavelength optical observations of the chromospherically active binary system MS Ser
J. Sanz-Forcada, D. Montes, M. J. Fernandez-Figueroa +2
We present here a continuation of our ongoing project of multiwavelength optical observations aimed at studying the chromosphere of active binary systems using the information prov…
