    The nature of Aquila X-1 (1978)
    [s.l.] : Nature Publishing Group
    Nature 271 (1978), S. 633-634 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Photoelectric photometry of nine stars in a 1 arc min field about Aql X-l was obtained in July and August 1976, using the 2.1 m reflector of the Kitt Peak National Observatory with the Cassegrain computer-photometer. Standardisation of these t/fiFdata was achieved through observations of standard ...

    A kinematic model for SS433 (1979)
    [s.l.] : Nature Publishing Group
    Nature 279 (1979), S. 701-703 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The emitting regions giving rise to the variable wavelength systems cannot be objects in mutual orbital revolution, for with a 164-d period and velocities of 0.15 c, keplerian orbits would have light-crossing times of the order of weeks, and the blue-and red-shifted emission lines could not ...

    Is HD26676 an unusual radio star? (1978)
    [s.l.] : Nature Publishing Group
    Nature 274 (1978), S. 137-137 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] HD26676 has been classified as B8V by Cowley3 and B7V by Racine2. The main sequence assignment by Racine is based on the equivalent widths of Balmer lines. U, B, V colours by Crawford4 and Cousins5 more closely correspond to B7V with a colour excess EB-V of about 0.15 mag. The distance to HD26676 ...

    Molecular hydrogen in X-ray astronomy (1974)

    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] It seems likely that this situation also applies to many or all galactic X-ray sources. The discrepancy is easily recognised in the Crab as it is a strong source with a well defined, nonvariable, power-law spectrum extending over many decades, but many other low latitude X-ray sources show a ...

    Distance to Cygnus X-1 (1975)

    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] CHENG et al.1 have recently re-examined our estimates2'3 of the distance to Cygnus X-l. They have noted that the Cepheid V547 Cyg is at d = 6.6 kpc, yet has colour excess 1.1, far less than predicted by a uniform reddening extrapolation. On this basis they conclude 'the only independent distance ...

    SS433 continues to perplex (1987)
    [s.l.] : Nature Publishing Group

    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] NEARLY a decade has passed since the popular press referred to the newly discovered object SS433 as the star that is "coming and going at the same time". Considerable observational and theoretical effort has been invested in this unique system1, which ejects two opposed, highly collimated jets of ...

    Notes: [Auszug] BULGARIA is not often viewed by Western astronomers as central to mainstream research. But on page 637 of this issue1, Tomov et al. report fascinating new observations of the odd star MWC560, an object first listed in the Mount Wilson Catalogue nearly 50 years ago2, although it was never studied in ...

    A QSO in a rich, distant cluster of galaxies (1983)
    [s.l.] : Nature Publishing Group

    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The cluster 0016 +16, at z =0.541 (rf. 2) is perhaps the best studied distant cluster of galaxies. Detailed multicolour photometry and isopleths3 show this cluster to be richer than the Coma Cluster, and remarkably normal except for its very large redshift. The brightest members have red magnitudes ...

    Surface density of faint high-redshift quasi-stellar objects (1987)
    [s.l.] : Nature Publishing Group
    Nature 327 (1987), S. 125-127 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Although the number counts of QSOs as a function of apparent magnitude are now reasonably well determined to faint limiting magnitudes, this is certainly not the case for the redshift distribution. It has been recognized for many years that very high-redshift QSOs (z 〉 3.4) are rare, and that the ...

    Notes: [Auszug] I HAD expected to dislike this book. The dust jacket (presumably not entirely the author's fault) is overripe in the extreme. Astronomers "rip the veil from spacetime" but are not allowed to touch the controls of the huge 200-inch telescope "because they might destroy it". As an observational ...
