Telescope Jumps: One Cause is Found . ... One tries to take out the sag of the secondary cage as the telescope is pointed toward the zenith. The second component tries to take out changes in the secondary piston caused by temperature changes of the truss structure. ... Second, the jumps only occur when the temperature data causes motions of the piston which go in a direction opposite to the direction in which the sag component is driving the secondary. ... One has to wonder how this can occur. ...

We obtained a series of images across the bright rim of the Orion Bar near the peaks of mm-wave molecular line emission with NICMOS cameras 1-3 (NIC1, NIC2, NIC3) in several filters on 1998 February 18. ... The suggestion of an H-H object does not seem compelling. ...

... Galaxies with polar rings (PRGs) are a unique class of extragalactic objects, consisting of a ring or disk of gas, stars and dust orbiting in a plane nearly perpendicular to the disk of a central galaxy. ... At present, there are only about two dozen kinematically confirmed galaxies in this PRG class, mostly from the Whitmore et al. (1990) catalogue, based on photographic images. ...

Next: Identification and Analysis of Binary Star Systems using Probability Theory . ... We present a computing code for modelling energy flux distributions, photometric indices and spectral line profiles of (non-)radially pulsating Main-Sequence stars. ... In the case of slowly rotating stars one can use the zero-rotation approximation to describe stellar pulsations. Such a model was used already by Cugier, Dziembowski & Pamyatnykh (1994) to study nonadiabatic observables of Cephei stars. ...
