Nearby and bright star samples from the Einstein Observatory stellar X-ray catalog
Abstract
Results from the study of nearby and/or bright star samples are presented based on the finalized catalog of identified stellar X-ray sources observed with the Imaging Proportional Counter (IPC) onboard the Einstein Observatory. Out of a total of about 10,000 X-ray sources whose data are organized in a relational database for easily accomplishing their analysis, data of X-ray sources identified with bright or nearby optical counterparts are presented. A brief summary of the major results known to date is presented, relevant properties of the optical catalogs used for the identifications are discussed, some new spectral results are shown, and a hint is given on expectations of future X-ray observations based on present best knowledge of X-ray emission from stellar sources.
