Analysis of the B and Be-star populations of the double cluster h and j Persei

We present blue optical spectra of 92 members of h and j Per obtained with the WIYN telescope at Kitt Peak National Observatory. From these spectra, several stellar parameters were measured for the B-type stars, including v sin i, Teff, log gpolar, M[lowast], and R[lowast]. Stroemgren photometry was...

Description
Summary:We present blue optical spectra of 92 members of h and j Per obtained with the WIYN telescope at Kitt Peak National Observatory. From these spectra, several stellar parameters were measured for the B-type stars, including v sin i, Teff, log gpolar, M[lowast], and R[lowast]. Stroemgren photometry was used to measure Teff and log gpolar for the Be stars. We also analyze photometric data of cluster members and discuss the near- to mid-infrared excesses of Be stars.
