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…
The Circumstellar Environment of the TTS SU Aurigae
J. M. Oliveira, B. H. Foing, J. Th. van Loon
In this contribution we investigate how a disk determines the physical and geometrical properties of the circumstellar environment of the T Tauri SU Aurigae. Our model of the spect…
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…
