  • The K-correction for LMXBs: an application to X1822-371 and GX339-4
    We present the K-correction for emission lines formed on the irradiated face of the companion stars in X-ray binaries. We compute this K-correction in a general approach as function of the mass ratio and the disc flaring angle. Our results combined with the detection of high energy emission lines arising from the donor star (e. g. Steeghs & Casares

  • The jet-powered optical nebula of Cygnus X-1
    We present Hα and [OIII] (5007 Å) images of the nebula powered by the jet of the black hole candidate and microquasar Cygnus X-1, observed with the 2.5-m Isaac Newton Telescope (INT). The ring-like structure is luminous in [OIII] and there exists a thin outer shell with a high [OIII]/Hα flux ratio. This outer shell probably originates in the

  • The Evershed Effect Observed with 0.2" Angular Resolution
    We present an analysis of the Evershed effect observed with a resolution of 0.2". Using the new Swedish 1 m Solar Telescope and its Littrow spectrograph, we scan a significant part of a sunspot penumbra. Spectra of the nonmagnetic line Fe I λ7090.4 allows us to measure Doppler shifts without magnetic contamination. The observed line profiles are

  • The Complementary Roles of Interferometry and Asteroseismology in Determining the Mass of Solar-Type Stars
    How important is an independent diameter measurement for the determination of stellar parameters of solar-type stars? When coupled with seismic observables, how well can we determine the stellar mass? If we can determine the radius of the star to between 1% and 4%, how does this affect the theoretical uncertainties? Interferometry can provide an

  • The chemical composition of the Galactic H II regions M8 and M17. A revision based on deep VLT echelle spectrophotometry
    We present new echelle spectrophotometry of the Galactic H II regions M8 and M17. The data have been taken with the VLT UVES echelle spectrograph in the 3100 to 10400 Å range. We have measured the intensities of 375 and 260 emission lines in M8 and M17 respectively, increasing significatively the number of emission lines measured in previous

  • The Bar Pattern Speed of Dwarf Galaxy NGC 4431
    We present surface photometry and stellar kinematics of NGC 4431, a barred dwarf galaxy in the Virgo Cluster undergoing a tidal interaction with one of its neighbors, NGC 4436. We measured its bar pattern speed using the Tremaine-Weinberg method and derived the ratio of the corotation radius, DL, to the bar semimajor axis, aB. We found DL/aB=0.6+1
