BVRI light curves are presented for 27 Type Ia supernovae discovered during the course of the Calan/Tololo Survey and for two other SNe Ia observed during the same period. Estimates of the maximum light magnitudes in the B, V, and I bands and the ini

The Guide Star photometric Catalog (GSPC-I; Lasker et al. 1988) is an all-sky set of photoelectrically determined BV sequences created to provide photometric calibrators for the Guide Star Catalog (Paper-I: Lasker et al. 1990, Paper-II: Russell et al

Optical Pulse of a Periodic Radio Star

Autor: J. G. Duthie, E. M. Hafner, C. Sturch

Publikováno v: Science. 160:415-416

The pulsating radio star reported by Hewish et al. (1) has been studied in the blue region of the optical spectrum and found to have a pulse amplitude less than 10 percent of the photon count expected for 18th magnitude. No upper limit to a sinusoida

A new UBV comparison of M67 and Hyades stars

Autor: C. Sturch

Publikováno v: Publications of the Astronomical Society of the Pacific. 85:724

New UBV observations reduce the discrepancies in the author's M67 and Hyades photometry reported earlier. Differences from the original Hyades photometry are negligible. The new data also agree with the original M67 photometry for (B- V) < 0.5, but d
