    The galactic ridge observed by Exosat (1985)

    Notes: [Auszug] We have used Exosat to map the distribution of X-ray emission in the galactic plane. In addition to numerous point sources, the map reveals a narrow continuous ridge of emission which extends along the galactic plane either side of the galactic centre out to ∼40° longitude. The origin of ...

    The big dipper: 4U1624-49 (1985)
    Springer
    Space science reviews 40 (1985), S. 195-200 
    Details

    Notes: Abstract We present a 6.3 hour observation of 4U1624-49 with the EXOSAT Medium Energy experiment. The X-ray light curve is dominated by a series of sharp dips in which the observed flux falls to ∼25% of the steady level on timescales of seconds. These dips are accompanied by strong variations in the spectral hardness consistent with large changes in the absorbing column density. No evidence is found for any dip periodicity, in contrast to the other four sources in which dip activity has been reported. We discuss the implications of these observations for models of low mass X-ray binaries.

    EXOSAT observations of the X-ray pulsar 4U1145-619 (1985)
    Springer
    Space science reviews 40 (1985), S. 429-432

    Notes: Abstract EXOSAT observations of the X-ray pulsar 4U1145-619 during June and July 1983 and July 1984 confirm that this source shows a regular 187 day outburst cycle in X-rays. The results from pulse timing and X-ray spectroscopy are discussed in terms of a model for 4U1145-619 involving an eccentric binary system in which there is variable accretion from the Be primary star onto a companion neutron star.

    A new view of the galactic plane with EXOSAT (1985)
    Springer
    Space science reviews 40 (1985), S. 437-441 
    Details
    ISSN: 1572-9672
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A new X-ray image of the galactic plane has been produced using the 45 arcmin square field of view of the Medium Energy Instrument on EXOSAT. This image shows a total of 64 sources including 18 new ones which include the first observation of persistent emission from the globular cluster bursters Terzan 1 and Terzan 5. The most important discovery from this image is a 2° wide ridge of diffuse emission symmetrical about the plane and extending from the galactic centre to 1″=±40°. The spectrum of this emission appears to be hard (α ∼ 1.2) with no significant absorption.
