... Since the reddening found for the stars in Table 13 was small, no reddening correction was attempted. ... These diamonds indicate the positions of very low mass, 3 Myr old, objects from the work of Burrows et al. ... This optical V versus R - I scheme is a very powerful method of detecting very low mass (VLM) objects. ... Because of this, young brown dwarfs are intrinsically no more difficult to observe in the optical than low mass stars at the age of Orionis. ...

... This version of the GHRS Instrument Handbook has had significant rewriting, mostly to incorporate information about the proposal writing software called RPS2 . ... We anticipate that Cycle 6 will be the last for the GHRS. ... Because Cycle 6 is short for both the GHRS and FOS, it is STScI's intention to schedule spectroscopic observations early in Cycle 6 to the greatest extent possible so that as many FOS and GHRS programs may be completed as is possible. ... Cycle 6 and the End of the GHRS . ...

... An examination of Figure 5 shows that the FSRQs in the DXRBS sample cover a much wider range of parameter space than those in the two previously existing complete samples of FSRQs , the 1 Jy and S4 samples ( radio data for these samples were taken from Stickel et al. 1994 and Stickel K?hr 1994, while X-ray data for these ... Also, the mean of the DXRBS sample's X-ray luminosity differs from that of both the 1 Jy and S4 samples' only at the 93 and level respectively. ...

Applied to data of flares on Gliese866 he was able to estimate the area of hydrogen emitting flare regions as 1-13% of the stellar surface. ... As partners in the project, Armagh Observatory has been asked to contribute to the selection process in exchange for priority access to the data which will eventually flow from the satellite. ...

... The Arecibo telescope upgrade is now nearing completion and we anticipate a resumption of tracking-mode observations for the carriage house, possibly as early as the second quarter of 1997. Therefore we are calling for the first round of observing proposals to use the 430- and 47-MHz carriage house instrumentation. ... 1) Obtain a cover sheet.

... The GW from coalescing compact binaries composed of NS and BH are the best understood of all astrophysical GW sources. A conservative lower limit to the event rate of galactic binary neutron star coalescence of about 1 per 100000 year follows from double pulsar   statistics studies (Narayan et al. ... In Figure  47 we show the rates of coalescence of binary WD and NS in a model elliptical galaxy   consisting of stars, depending on time elapsed since the (assumed instantaneous) star formation. ...
