An Einstein Observatory SAO-based catalog of B-type stars
About 4000 X-ray images obtained with the Einstein Observatory are usedto measure the 0.16-4.0 keV emission from 1545 B-type SAO stars fallingin the about 10 percent of the sky surveyed with the IPC. Seventy-fourdetected X-ray sources with B-type stars are identified, and it isestimated that no more than 15 can be misidentified. Upper limits to theX-ray emission of the remaining stars are presented. In addition tosummarizing the X-ray measurements and giving other relevant opticaldata, the present extensive catalog discusses the reduction process andanalyzes selection effects associated with both SAO catalog completenessand IPC target selection procedures. It is concluded that X-rayemission, at the level of Lx not less than 10 exp 30 ergs/s, is quitecommon in B stars of early spectral types (B0-B3), regardless ofluminosity class, but that emission, at the same level, becomes lesscommon, or nonexistent, in later B-type stars.

2000 A UV imaging of a 6 deg diameter field around MU Aurigae
UV imagery of a 6 deg diameter field centered on Mu Aurigae in thegalactic plane was obtained with the SCAP 2000 experiment dedicated toan UV sky survey. Photometric UV magnitudes at 2000 A are given here formore than 500 stars detected in the field. A star-counting method isapplied to give a fine description of the interstellar matterdistribution up to 1000 pc. The mean space density for B8-A3 stars isderived. Stars with an UV excess are detected and spectralreclassification of some single or binary stars is suggested.
