  • Angular distribution of satellite galaxies from the Sloan Digital Sky Survey Data Release 4
    We explore the angular distribution of two samples of satellite galaxies orbiting isolated hosts extracted from the Sloan Digital Sky Survey Data Release 4. We find a clear alignment of the satellites along the major axis of their hosts when restricting the analysis to red-coloured hosts. The anisotropy is most pronounced for red satellites of red

  • An Observational Study of Line-Profile Variable B-stars in Multiple Systems
    We present the results of an observational study of the pulsational behavior of the line-profile variable binary components of κ Sco, λ Sco and ɛ Lup. Our research is situated in the framework of a systematic long-term project targeting line-profile variable B-stars in close binaries, with the aim to search for tidally enhanced oscillations.

  • A Spectroscopic Survey of NGC 7419
    The reddened open cluster NGC7419 is believed to have a very high fraction of Be stars and present an exceptionally high number of red supergiants (five for no blue supergiants). We present the first results of our recent spectroscopic observations of the cluster, which confirm the high fraction of Be stars. We also find spectral types in good

  • A Simple Model for the Distribution of Quiet-Sun Magnetic Field Strengths
    We derive a first-order linear differential equation describing the shape of the probability density function (PDF) of magnetic field strengths in the quiet Sun. The modeling is very schematic. It considers convective motions which continuously supply and withdraw magnetic structures. In addition, a magnetic amplification mechanism increases the

  • A High-Resolution Spectroscopic Survey of β Cephei Pulsations in Bright Stars
    We present preliminary results of our high-resolution (R≥50000) spectroscopic survey of line-profile variations in stars with spectral types similar to β Cephei stars. In this paper we focus on the observations obtained on La Palma with the William Herschel Telescope (WHT) and with the Nordic Optical Telescope (NOT), to complement both the Southern

  • A detection of the donor star of Aquila X-1 during its 2004 outburst?
    Phase-resolved high-resolution optical spectroscopy has revealed narrow NIII and HeII emission lines from the soft X-ray transient Aquila X-1 during its 2004 outburst that move as a function of the orbit consistent with the phasing of the donor star. Under the assumption that these lines come from the irradiated side of the donor star, we can
