Hα Interferometric Optical and Near Infrared Photometric Studies of Star Forming Regions - Part One - the Cepheus-B / SH:2-155 / CEPHEUS-OB3 Association Complex Abstract image available at:http://adsabs.harvard.edu/cgi-bin/nph-bib_query?1993A&A...273..619M&db_key=AST
Empirical temperature calibrations for early-type stars Three temperature calibrations of suitable photometric quantities havebeen derived for O and B stars. A sample of 120 stars with reliableT(eff.) determinations has been used for establishing each calibration.The different calibrations have been critically discussed and compared.Temperature determinations for 1009 program stars have been obtainedwith an accuracy of the order of 10 percent.

Search for light variability among eight stars with anomalous helium content A search for periodic light variability was carried out among eightstars with anomalous helium content. No variability was detected duringthe observation period for HD 178993, HD 207538, and HD 209339. Theperiod obtained for HD 184927 by Bond and Levato (1977) was confirmed.For HD 191980, HD 208266, and HD 217833, photometric variability wasdetected and periods were obtained.
