  • Photometry of sunspot pores from partial eclipse observations.
    White-light images, centered at λ6708A, were obtained at the Swedish Solar Telescope, La Palma, on occasion of the 1994 May 10 partial solar eclipse. From the recorded information, 5 frames showing several pores together with the moon's limb were selected for detailed photometric analysis. The observed intensity profile of the moon's limb projected

  • Morphological segregation of early-type galaxies in the Virgo cluster
    We present evidence for a morphological segregation of early-type galaxies with different isophote shapes in the Virgo cluster. Comparing local projected densities around galaxies, we find that, independently of their classification as elliptical or lenticular, galaxies with boxy isophotes are located in local density enhancements, while galaxies

  • Monitoring of active galactic nuclei. VI. The quasar MKN 876.
    We present the results of a 6 month monitoring campaign of Mkn 876, a low luminosity quasar with M_abs_=~-24. High resolution spectroscopy and direct imaging in the Johnson filters B, V, R, I was carried out in the first half of 1990. Line and continuum light curves are presented. Mkn 876 showed a decrease of 17% in the continuum over the whole

  • Major axis kinematics of 15 early-type galaxies in the Fornax cluster.
    Major axis rotation curves and velocity dispersions profiles, extending out to about one effective radius, are presented for 15 ellipticals and S0's out of the photometric sample of Fornax cluster galaxies studied by Caon et al. (1994). A brief description of the spectroscopic and photometric characteristics of each galaxy is provided, together

  • Linear and non-linear limb-darkening coefficients for LTE model atmospheres.
    Linear, quadratic, and square root limb-darkening coefficients have been computed by means of least squares fits to model atmospheres by Kurucz (1991) with the main purpose of facilitating the analysis of light curves of eclipsing binaries. Results are compared with previously published values using the same or different models and various fitting

  • Dynamics of the solar granulation. III. Fractional diffusion.
    In most papers dealing with random motions and diffusion of small magnetic elements in the photosphere, the convective flows and in particular the granulation are considered as drivers of these motions. The results of these works have been discussed in terms of the fractal dimension of the granulation as seen in intensity pictures. So far neither a
