Long-term X-ray observations of Cen X-3, GX 301-2 (4U 1223-62) GX 304-1 (4U 1258-61), and 4U 1145-61
We present 7 year (1969--1976) X-ray time histories for the sources Cen X-3, GX 301--2, GX 304--1, and 4U 1145--61, with 10 day time resolution. Time series analysis confirms the 41.5 day periodicity
Invisibility of the Lorentz Contraction
It is shown that, if the apparent directions of objects are plotted as points on a sphere surrounding the observer, the Lorentz transformation corresponds to a conformal transformation on the surface
Discovery of a 176 day period in 4U 1820-30
Long-term X-ray observations of the X-ray burster 4U 1820-30 (in NGC 6624) reveal a significant 176.4 +/- 1.3 day period. These data were obtained by a 3-12 keV detector on the Vela 5B satellite
Long-term observations of x-ray sources: The aquila-serpens-scutum region
We present long-term (1969-1976) observations of galactic X-ray sources in the Aquila-Serpens-Scutum region. Data were obtained by the 3--12 keV detector on the Vela 5B satellite. The time histories
The 1973 X-ray transient V0332+53
A bright transient x-ray source, V0332+53, was observed by Vela 5B for 3 months in 1973. It was first clearly detected in the 10 day period centered on 1973 June 1, rose to an intensity of approx.1.4
111-day periodicity of X-ray transient A0535 + 26
A0535 + 26 is the prototype object of the hard spectrum, pulsating X-ray transients associated with Be companions. Our analysis of its 1969–79 X-ray (3–12 keV) time history, measured by the Vela 5B
Neutron Yields from Individual Fission Fragments
Two new methods are used to obtain data on neutron yield ${\ensuremath{\nu}}_{f}$ as a function of the mass number $M$ of the emitting fission fragment; the results suggest changes in fission theory.
