The observational data for the 124 cataclysmic and low-mass X-ray binaries of known orbital
period are compiled. It is found that the eruption properties are very well correlated with the …

Soft X-ray sources are defined as that class of objects whose emission occurs primarily in
the energy range from 0.15 to 2 keV. Sixteen objects which have already been detected as …

Solar-type activity over the whole range of the electromagnetic spectrum is a phenomenon
inherent in the majority of low-and moderate-mass main sequence stars. In this monograph …

A method of determination of parameter sets characterizing models of starspots is described.
The method makes use of a systematic integral notation in the description of the darkening …

Observations indicating the presence of stellar chromospheres, that is hot envelopes around
stars are summarized. Undisputed indicators (called type I) for hot stellar envelopes are …

We have developed a multichannel spectrophotometric detector system using a 1024

Quantitative information is obtained on the chromospheres and transition regions of M dwarf
stars, in order to determine how the outer atmospheres of dMe stars differ from dM stars and …
