  • Characterizing bar structures: application to NGC 1300, NGC 7479 and NGC 7723
    Detailed surface photometry has been carried out for three barred galaxies with use of high resolution CCD broad-band images in the B, V and I bands. Using azimuthal luminosity profiles and their decomposition into Fourier Series, the structural parameters (length and strength) of the bars in the three galaxies have been obtained. We have also

  • CCD Photometry of Cometary Nuclei, I: Observations from 1990-1995
    CCD photometry of 18 Jupiter family comets, observed at medium and large heliocentric distances, was carried out between April 1990 and July 1995. This is part of a long-term observational program designed to obtain their nuclear magnitudes. The observations were made with the 1.54-m Danish Telescope at ESO La Silla, the 2.5-m Nordic Optical

  • A TiO study of the black hole binary GRO J0422+32 in a very low state
    We present 53 simultaneous photometric (I band) and spectroscopic (6900-9500Å) observations of GRO J0422+32, taken during 1997 December. From these we determine that J0422+32 was in its lowest state yet observed, at I=20.44+/-0.08. Using relative spectrophotometry, we show that it is possible to correct very accurately for telluric absorption

  • Z physics effects of an additional non-sequential bottom quark
    We analyze the Zff vertex in the framework of models that add a new bottom quark in a non-sequential way and we evaluate the tree level contribution to the LEP/SLC observables ΓZ, Rb and Rl. We obtain bounds for the mixing angles from the experimentally allowed contour regions of the parameters ΛL,R introduced here. In order to get a more

  • Transient Effects in ISOPHOT Data: Status of Modelling and Correction Procedures
    The calibration of ISOPHOT observations is hampered in many cases by the transient response of the detectors. Here we outline the behaviour observed in flight for the different ISOPHOT detectors. We also present some of the procedures which are currently used to correct transient effects and their implementation in the ISOPHOT Interactive Analysis.

  • The spectral variations of the O-type runaway supergiant HD 188209
    We report spectral time series of the late O-type runaway supergiant HD 188209. Radial velocity variations of photospheric absorption lines with a possible quasi-period of ~6.4d have been detected in high-resolution echelle spectra. Night-to-night variations in the position and strength of the central emission reversal of the Hα profile occurring
