UBV photometry of short period cepheids 613 UBV observations of 15 pulsating variables collected on the 1 mreflector at ESO, La Silla, Chile are reported. The variables observedhave periods between one and three days.
Stars of spectral types A and B in the southern galactic halo. I - UBV photometry The results of photoelectric UBV photometry of 234 AB stars in thesouthern galactic halo are presented. The stars were chosen from theCurtis Schmidt objective-prism survey of Preston and Shectman andcomprise a sample of halo objects selected without kinematic bias. Themajority of the stars lie in the region of the (U - B,B - V) planeoccupied by field and globular cluster blue horizontal-branch stars.
