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…
Magnetospheric Accretion and Winds on the T Tauri Star SU Aurigae: Multi-Spectral Line Variability and Cross-Correlation Analysis
J. M. Oliveira, B. H. Foing, J. Th. van Loon +1
SU Aurigae is a T Tauri star that was well monitored during the MUSICOS 96 multi-site campaign. We present the results of the spectroscopic analysis of the circumstellar environmen…
Circumstellar emission and flares on FK Comae Berenices: Analysis and modelling of Balmer and He I D3 line variations
J. M. Oliveira, B. H. Foing
We present results on spectroscopic observations of the fast-rotating active giant FK Comae, obtained mainly with the ESA-MUSICOS spectrograph at the Isaac Newton Telescope (INT) i…
