Simultaneous Multi-Wavelength Observations of an Intense Flare on AD Leonis

Abstract

We report on the first successful coordinated observations of stellar flares carried out on March 28, 1984 simultaneously over a wide range of wavelengths, from UV to microwaves, using the IUE satellite, three ESO telescopes at La Silla (Chile) and the VLA at Socorro (NM, USA).

Plasma Astrophysics

“…Rodono et al, 1989). The observers agree that they appear to be qualitatively similar to the Sun, but release 2 -3 orders of magnitude more energy than the largest solar flares.…”

Balmer and soft X-ray emission from solar and stellar flares

“…It was recently shown by Butler, Rodono and Foing (1988), (henceforth Paper I), that there exists a well defined linear correlation between the integrated energy emitted in H 7 and soft X-rays in stellar flares. Their data also included a single solar flare for which the equivalent soft X-ray flux in the EXOSAT CMA passband (0.04-2 KeV) had been computed by Doyle et al (1988).…”
