(American Astronomical Society, 1989-12)Reddening line parameters in the UBV system have been derived for early-type stars in six restricted (2[degrees symbol]-3[degrees symbol] radius) Milky Way fields associated with open clusters and/or associations. The ...

(American Astronomical Society, 1986-07)New photoelectric UBVphotometry is presented for stars in NGC 6087, the cluster containing the 9[d over dot]75 Cepheid S Normae. The data are used with published photoelectric observations for cluster stars to redetermine ...
-
(American Astronomical Society, 1992-09)New photoelectric UBV photometry of 27 stars and spectroscopic observations of 12 stars are presented for NGC 129, the cluster containing the 8[d over dot]00 Cepheid DL Cas. The photometry is used to restandardize previously ...

(American Astronomical Society, 1992-11)New photoelectric UBV photometry of 45 stars and spectroscopic observations of 24 stars are presented for NGC 1647, the cluster associated with the 3[d with dot below]15 Cepheid SZ Tauri. The resulting photometry, spectral ...

Galactic clusters with associated Cepheid variables. IV. C2128+488 (Anon. Platais) and V1726 Cygni (American Astronomical Society, 1994-05)New photoelectric UBV photometry of 32 stars, photographic UBV photometry of 120 stars, and spectroscopic observations of 8 stars are presented for C 2128+488 (Anon. Platais), the cluster associated with the 4[d over dot]237 ...

(American Astronomical Society, 1993-03)We report UBV photometry for fields surrounding four long-period Cepheids in the Southern Milky Way. No potential early-type companions are detected around XY Car, which appears to be relatively isolated. However, an ...
