EXOSAT observations of the 19 Nov. 1978 and 25 Mar. 1979b gamma bursters are presented, for the 0.02 - 2.5 keV energy range. No source was detected in either case, leading to temperature upper limits for the neutron stars assumed to be present of 105- 106K. Polar cap accretion rates are constrained to values of 10-12- 10-18M_sun;/y km2. The EXOSAT

Mg II emissions in the IUE spectra of 91 cool stars are analyzed in a systematic search for interstellar components. About 60 percent of the stars show evidence of interstellar contamination. The radial velocities of the features show that even at short distances (d less than 30 pc) the motion of the local interstellar medium (LISM) agrees with
