Coordinated EXOSAT and Spectroscopic Observations of Flare Stars and Coronal Heating

Rodono, M.; Butler, C. J.

We present some preliminary results of simultaneous monitoring of the two flare stars, UV Ceti and EQ Peg with EXOSAT and ground based optical spectro-scopy. A strong correlation, found between the Hγ emission and the soft X-ray flux, over several hours of observation of UV Ceti, suggests that much of the low level X-ray flux which has previously …

Simultaneous X-Ray and Photometric Observations of the Flare Star YZ CMi

Doyle, J. G.; Butler, C. J.

Broad-band photometric observations of YZ CMi show a 1.2 magnitude U-band flare, however, simultaneous X-ray observations from EXOSAT show no detectable increase. It is suggested that the energy was dissipated before reaching the corona. Two long duration U-band enhancements detected during the optical monitoring may have been the result of back-h…
