Star formation in the Cepheus Flare region - II. A-type stars associated with IRAS sources
In order to reveal the star-forming history of the molecular cloudcomplex we studied the intermediate mass stellar population in theCepheus Flare region. (Paper I dealt with the distance and the youngstellar object candidates of the region.) Correlating the IRAS PointSource Catalogue and Faint Source Catalogue positions with those of 1214B8-A8 and 1760 F0-F5 type stars brighter thanF12F25ν212ν225 ≈ 4.3, V>> 13mag and classified during an objective prism survey, weidentified 19 stars showing far-infrared excess emission in the CepheusFlare region. In addition to the 16 stars whose counterparts are givenin the IRAS catalogues, we found three more stars with infrared excessnot recognized before. In order to identify the young medium-mass starsassociated with the Cepheus Flare molecular clouds we observed theoptical spectra of the IR-excess stars, and using published opticalphotometry and the IRAS data we examined their spectral energydistributions (SEDs) and IRAS two-colour diagram. The observationsresulted in the discovery of a new Herbig Ae/Be star, BD +68°1118,coinciding with IRAS 21169+6842. More evolved HAe/Be stars may beSAO19953, BD +67°1314 and BD +69°1231, whose Hα linesshowed weak emission components. Possible β Pictoris- or Vega-typestars may be HD 203854, HD 212826 and HD 216486, whereas thefar-infrared fluxes at the positions of BD +72°1018, HD 210806 andHD 217903 can be attributed to the heating of the interstellarenvironment. We used distances and radial velocities of the starsderived from the spectroscopy and published optical photometry asindicators of their relations to the clouds. Information on theenvironment of the observed stars deduced from the diffuse interstellarband at λ6613 is briefly discussed.

Locations of the components of triple star systems north of +70 deg
Micrometric measurements of triple systems north of +70 deg declinationwere made with the 10.5-inch Fraunhofer refractor of Munich UniversityObservatory. Absolute positions of all measured components were derivedby using the positions of the main stars as given in the catalog AGK3and, in some cases, also in the SAO-catalog.
