    Notes: [Auszug] Liller1 searched for an optical counterpart of the rapid burster and found a highly reddened compact cluster with a red magnitude rar = 21 in the error box of the rapid burster6. This has been identified as a globular cluster by Kleinmann et al.7, with the help of IR observations. The ...

    Notes: [Auszug] The energy of the synchrotron electrons of Per (Algol) is fixed by the optical photon energy (about 0.8 eV) and the X-ray photon energy (4 keV); the relativistic factor for these electrons is about 75. The observed radio frequency (about 8 x 109 Hz) gives the strength of the magnetic field as 1.6 ...

    Radio and infrared flares in CYG X-3 (1987)
    Springer
    Astrophysics and space science 133 (1987), S. 229-231 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The observed radio and infrared flares in Cyg X-3 are explained as due to interaction of X-rays and high-energy gamma-rays with clumps of matter in a cocoon around the object. The observed repetitive period of the radio flares is explained as the beat period between the 4.8 hr periodicity and the Keplerian period of matter in the cocoon.

    Variability of the dispersion measure of the pulsar NP 0532 (1974)

    ISSN: 1572-946X

    Notes: Abstract It is hypothesized that NP 0532 is seen from the Earth through a filament of high density of the Crab nebula. The variability of the dispersion measure of the pulsar NP 0532 is explained as due to variation in ionization produced in the filament by varying soft X-ray flux of NP 0532.

    Elemental abundance enhancement in cosmic rays and their relation to interstellar depletion (1981)
    Springer
    Astrophysics and space science 77 (1981), S. 521-527 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We have shown that a correlation exists between the enhancement of abundance of heavy nuclei in cosmic rays and their depletion in interstellar space. A correlation also exists between the abundance enhancement and condensation temperature. We suggest that these correlations imply that much of the heavy nuclei content of cosmic rays may come from grains. A possible model is that grains in star-cloud complexes are accelerated to injection energies by radiation pressure in a supernova explosion and, subsequently, the grain debris is accelerated by shocks to cosmic ray energies.

    Solar cycle model for oscillating transient X-ray sources (1976)
    Springer

    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The oscillations observed recently in the transient X-ray source A1118-61 are attributed to variations in the magnetic activity of a rotating white dwarf similar to the 11-year solar activity cycle. The transient nature, in analogy with the sun, is attributed to the variation in the strength of the cycle.

    A model for the rapid X-ray Burster (1979)
    Springer
    Astrophysics and space science 63 (1979), S. 125-129 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A model for the Rapid X-ray Burster (MXB 1730-333) based on an accreting rotating magnetized neutron star in a binary system is proposed. The bursts are attributed to instabilities produced at an equilibrium surface above the poles of the neutron star, which is created by the infalling gas supported by a combination of radiation and relativistic gas pressures. The special feature of the proposed model is that, when accretion onto the poles is prevented by radiation pressure, relativistic gas streams out of the polar region.

    Infrared bursts from liller I/MXB 1730-333 (1980)
    Springer

    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The observation of infrared bursts from the globular cluster Liller I has been reported by Kulkarniet al. (1979) and confirmed by Joneset al. (1980). The infrared bursts which resemble Type I X-ray bursts in their characteristics are plausibly attributed to a cyclotron maser instability operating at few tens of neutron star radii above the poles of a magnetized neutron star in a binary system. It is suggested that similar infrared bursts should in general be observable from Type I X-ray burst sources.
