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 h

During the era of the Solar Maximum Mission (SMM) observations of the Sun, significant developments were taking place in the parallel field of stellar astrophysics which led to the concept of the so-called “solar-stellar connection.” In the same

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 t

In the solar corona the opacities of some of the prominent X-ray emission lines are on the order of τ ≈ 1 over typical coronal path lengths. We present and discuss a particular solution of the radiative transfer problem involving an extended, sphe

The flight of a multilayer-coated mirror on a sounding rocket experiment on March 17, 1988 which was used to obtain photometric images of the sun just prior to solar eclipse is discussed. The rocket payload and the choice of passband are described. T

A tensor formulation of the equation of radiative transfer is derived in a seven-dimensional Riemannian space such that the resulting equation constitutes a divergence in any coordinate system. After being transformed to a spherically symmetric comov

The first detection of both quiescent and flaring soft X-ray emission from a dMe flare star, Proxima Centauri (dM5e) is reported. The data are analyzed for temporal variability and spectral characteristics. The quiescent state is characterized by a m

The Einstein Imaging Particle Counter observed a major X-ray flare in its entirety during a 5-hr period of simultaneous observations, with the IUE, of the dM5e flare star Proxima Centauri in August, 1980. The detailed X-ray light curve, temperature d
