Coronal Structure: Legacy of EUVE
Extreme ultraviolet spectra (lambda lambda 70-740) and light curves (lambda lambda 75-175) of the spectroscopic binary system lambda And (HD 222107), were obtained with the Extreme Ultraviolet Explorer satellite (EUVE) in July and August 1997. Two flares were detected during the observations which spanned 15 days, or almost three-quarters of the orbital period of 20.5 days. The Emission Measure Distribution (EMD) of lambda And derived from a line-based analysis, shows an increasing slope with the temperature from 3.1x10(exp 6) K through 2.0x10(exp 7) K, as well as a remarkable 'bump' around T(sub e) approx. equals 10(exp 6.9) K. During the flares small changes were detected in both the general slope of the EMD and the height of the bump, but the bump remained very stable in its temperature. Electron densities of N(sub e) approx. equals 10(exp 12.7) cm(exp -3) are indicated at temperatures of 10(exp 7) K using Fe XXI and Fe XXII emission features.
