    UVMag: stellar formation, evolution, structure and environment with space UV and visible spectropolarimetry

    Important insights into the formation, structure, evolution and environment of all types of stars can be obtained through the measurement of their winds and possible magnetospheres. However, this has hardly be...

    Album: A Tool for the Analysis of Slitless Spectra and its Application to ESO WFI Data

    ALBUM is a general-purpose tool to visualize and screen large amounts of slitless spectra∈dex slitless spectra. It was developed for a search for emission-line stars in SMC and LMC clusters. The observations w...

    An optical supernova associated with the X-ray flash XRF 060218

    A link between long γ-ray bursts (GRBs) and supernovae has been established, but whether there is a similar relationship between the weaker and softer X-ray flashes and supernovae is unclear. GRB/XRF 060218, s...

    The Supernova/GRB Connection

    We discuss the possible connection between supernova explosions (SN) and gamma-ray bursters (GRB) from the perspective of our current understanding of SN physics. Core collapse supernovae (SN) are the final st...

    Predicting the Outbursts of the Be Star µ Cen

    By analyzing 409 high-resolution spectra covering the whole Paschen continuum of the Be star µ Cen taken from 1992 to 1997, we found six genuine periods in the photospheric radial-velocity variations. The propert...

    Be Stars in Young LMC Clusters

    Slitless field Hα spectroscopy with a resolution of 0.2 nm has detected numerous Be stars in 3 young open star clusters in the LMC but only a few each in one Galactic and one LMC cluster. The line widths indic...

    Simultaneous Photometry and Spectroscopy of the Rapid Variability of the Be Star η Cen

    The reality of the previously reported triple-wave light curve (Cuypers et al. 1989, A&A Suppl. 81, 151), and relations between rapid line profile and brightness variations of the B1-2III-Ve star η Cen (HD 127972...

    High—Precision Continuum Rectification

    We sketch a new method for the accurate flux calibration and normalization of stellar spectra. This is of particular importance for the analysis of rapidly rotating early-type stars. Some preliminary log g determ...

    Rapid Multicolour Variations of Selected Southern Be Stars

    Many previous surveys of the rapid variability of Be stars (e.g., Balona et al. 1987, Cuypers et al. 1989, Balona et al 1992) were limited to the Strömgren b-band only. We have undertaken a new observational effo...

    A Search for Beta Cephei Stars in LMC and SMC

    The β Cephei instability is believed to be caused by the к-mechanism. Model calculations, based on revised metal opacities, show this mechanism to be strongly sensitive to metallicity (e.g., Dziembowski, W. A. & ...

    Periodic Variability of Be Stars: Nonradial Pulsation or Rotational Modulation?

    A large fraction of Be stars show periodic light and line profile variations with a timescale of about one day. The mechanism which causes these periodic variations has been attributed to nonradial pulsation (...

    Observational Aspects of Stellar Seismology

    It might be argued that the term observational asteroseismology should perhaps still be used slightly more sparingly than current practice suggests. Compared to helioseismology which already has a large number...

    Preparing Analysis of Hubble Space Telescope Data in Europe

    Since no image processing system will ever be complete, the best system is the one which is the easiest to supplement. We therefore discuss various solutions to the typical problems encountered in porting appl...

    A photometric and spectroscopic study of the short-period eclipsing binary BV Eridani

    UBV observations of the short-period eclipsing binary BV Eri are reported and analyzed. The radial velocity curve is given. The system shows a light curve distortion, making an analysis difficult...
