Observations of X-Rays from Flare Stars with ANS
Abstract
Observations during which X-ray emission from flare stars was detected for the first time, are described. An X-ray flare was detected from YZ CMi at 0.28 keV and 1-7 keV, although no optical or radio coverage was available. During a very large optical flare from UV Ceti, X-ray emission at 0.28 keV only was detected. Upper limits for X-ray emission from several small optical flares of UV Ceti are obtained. Implications for X-ray flare models, the diffuse X-ray background, and low-energy cosmic-ray flux are examined.
