Three Lynds Bright Nebulae
The region from l=139.5d-141.0d, b=-2.5d-3.0d contains three faint LyndsBright Nebulae. LBN 140.77-1.42 and the lower portion of LBN 140.07+1.64are associated with an intriguing arc of neutral hydrogen at Perseus Armvelocities and morphologically associated CO and dust emission. Youngstellar objects (YSOs) are found along the length of the H I feature,several with velocities indicating a connection with the features in themolecular and neutral material. The arc-shaped ionized emission from LBN139.57+2.70 is associated with a hole in H I also at Perseus Armvelocities and contains a YSO at its edge. The hole is consistent with awind-driven bubble blown by an early B star. This paper uses data fromthe Canadian Galactic Plane Survey to characterize these regions,studying the gas, dust, and YSO components of the nebulae and thesources of illumination for the ionized gas.

We give a common version of the two catalogues of Mean Radial Velocitiesby Wilson (1963) and Evans (1978) to which we have added the catalogueof spectroscopic binary systems (Batten et al. 1989). For each star,when possible, we give: 1) an acronym to enter SIMBAD (Set ofIdentifications Measurements and Bibliography for Astronomical Data) ofthe CDS (Centre de Donnees Astronomiques de Strasbourg). 2) the numberHIC of the HIPPARCOS catalogue (Turon 1992). 3) the CCDM number(Catalogue des Composantes des etoiles Doubles et Multiples) byDommanget & Nys (1994). For the cluster stars, a precise study hasbeen done, on the identificator numbers. Numerous remarks point out theproblems we have had to deal with.
| Observational studies of Cepheids. II - BVRI photometry of 112 Cepheids
Over 4000 differentially determined photoelectric BVRI observations andthe resulting light curves are presented for 112 Cepheids accessiblefrom Northern Hemisphere observatories. The internal precision of thesedata is better than + or - 0.01 mag, and the accuracy of transformationto the Johnson BVRI system is nearly as good.
