Walraven photometry of nearby southern OB associations Homogeneous Walraven (VBLUW) photometry is presented for 5260 stars inthe regions of five nearby southern OB associations: Scorpio Centaurus(Sco OB2), Orion OB1, Canis Major OB1, Monoceros OB1, and Scutum OB2.Derived V and (B - V) in the Johnson system are included.
Miscellaneous spectroscopic notes Results of slit-spectrograph observations are reported for approximately260 stars. The data presented range from recognition of many new Ap, Am,and other unusual stars to H-alpha observations of early-typesupergiants and Be stars. The material discussed was obtained over thepast 40 years at a number of U.S. observatories and at the DominionAstrophysical Observatory in Victoria, B.C.
Optical and infrared photometry of southern early-type shell stars and pre-main-sequence variables A catalogue of optical and infrared photometry is presented covering theepoch 1980 to 1984 for a sample of 53 pre-main-sequence stars and otheremission-line objects, mainly of early spectral type. The JHKL data aregenerally simultaneous with optical photometry in either the UBVRI orStromgren uvby systems, and the H beta index is used as a photometricmonitor of spectrum variability. This catalogue will form a valuabledata set for future studies of the nature and origin of variability inthis class of object.
