Ephemeris for Physical Observations of Jupiter, 1882-83

A Revised Ephemeris and Fuse Observations of the Supersoft X-ray Source Cal 83 Based on Observations Made with the Nasa-cnes-csa Far Ultraviolet Spectroscopic

Explorer. FUSE is operated for NASA by the Johns Hopkins University under NASA contract NAS5-3298. ABSTRACT A new ephemeris has been determined for the supersoft X-ray binary CAL 83 using MACHO photometry. With an improved orbital period of 1.047568 days, it is now possible to phase together photometric and spectroscopic data obtained over the past two decades with new far ultraviolet spectra t...

83-05-10.1 Physical Access Control

Access control devices and systems comprise an important part of every security system. Even the simplest single-door access control system includes at least an electric strike to automatically unlock the door, a timer to make sure that the door does not stay open all day, and a bell or light to indicate when the door is opened or that it has not reclosed properly. In a large-scale security sys...

Searching for comets encountering Jupiter . Second campaign observations and further constraints on the size of the Jupiter familypopulation

| The results from the second campaign of the search for comets in the vicinity of Jupiter are presented. As in the previous campaign, we nd no comets. This result is used to calculate upper limits on the size of the Jupiter family population of comets. The numbers found are the same as in the previous campaign, but have the advantage that the lack of complete discovery at the limiting magnitud...

Stellar dynamics observations of a double nucleus in M 83

We report on the discovery of a double nucleus in M 83, based on measurements of the line of sight velocity distribution of stars observed at near infrared wavelengths with the VLT ISAAC spectrograph. We observe two peaks separated by 2. 7 in the velocity dispersion profile of light from late-type stars measured along a slit 0. 6 wide, centered on the peak of K band emission and with P.A. 51.7 ...
