... The chemically peculiar star HD965 belongs to a rare type of very slow rotators. As far back as in the 90s, G.Mathys (ESO, Chile) supposed its extremely slow rotation as observing split Zeeman components in the spectrum, from which he measured the magnetic field on its surface. Field variation proved to be very slow, and G.Mathys determined that the variability period should be longer than two years. ... Up to now, only two stars with periods longer than 20 years are known. ...

... An array of vertical electrodes is formed over the silicon surface and horizontal charge transfer columns are defined by implanted channel stop regions in the wafer surface. ... The array operates as follows: when an image is focussed onto the CCD, photons which penetrate the electrode structure generate electron-hole pairs in the underlying silicon substrate, and the signal charges are stored in the potential wells beneath the electrode structure (gates). ...

... We have used a coupled dynamical and chemical model to examine the chemical changes caused by the passage of a density wave propagating into the protostellar cloud. ... The chemical coupling between gas and dust causes locally increased number densities of active ra dicals, such as C, N, O, NH, and OH, and hydrogen saturated molecules CH 4 , NH 3 and H 2 O. We show that chemical evolution in the post-wave gas can account for the observed abundance of water and NH 3 observed in interstellar clouds. ...

• Abstract

Most current theories for magnetospheric emission can be grouped into polar cap, outer gap, and nebular models. These models, at least in some cases, need not be mutually exclusive; the Crab pulsar (among others), for example, shows clear evidence for pulsed emission from the magnetosphere and unpulsed emission from the surrounding nebula. ... This suggestion is strengthened by observation of a distinct soft emission component, consistent with the cooling scenario, from several of these pulsars. ...
