    On the evolution of rotation and magnetism from solar-like stars to red giants using Kepler data
    More than 40 years ago, Skumanich (1972) showed how rotation and magnetic activity decreased with the age of a solar-like star. While this result was based on...

    On the extreme properties of massive galaxies at high redshifts
    Massive (&#8805 10 11 M⊙) galaxies at high redshift (z &#8805 1.5) remain mysterious objects. Their extremely small sizes (effective radii of 1-2 kpc) make them...

    On the fate of the most massive stars
    Radiation-driven mass loss largely determines the life expectancy of massive stars. I will present our most recent mass-loss predictions for massive stars...

    On the invention of the telescope and the paintings of Jan Brueghel
    Jan Brueghel depicted telescopes in four paintings spanning the period between 1609 and 1621. We have investigated the nature and the origin of these telescopes...

    On the Las Cumbres Observatory Global Telescope
    Mr. Wayne Rosing, founder and director of the Las Cumbres Observatory Global Telescope Network, will discuss their plans to build a global network of more than...

    On the multiplicity of optically bright quasars with ALMA/ACA
    I will present ALMA Compact Array (ACA) 870 micron data of 28 infrared-bright SDSS quasars at redshifts 2 – 4 with estimated star formation rates beyond 1000...

    On the origin of the absorption and emission line components in the spectra of PHL 293B
    From the structure of PHL 293B and the physical properties of its ionizing cluster and based on results of hydrodynamic models, we point at the various events...

    Optical and infrared studies of Galactic open clusters
    In the first (optical) part, we present our recent results on mass and luminosity function of Galactic open clusters, a new statistical study based on the ASCC...

    Optical and NIR studies of short period low mass X-ray binaries (LMXB)
    I present some recent results from our Optical and NIR studies of five short period low-mass X-ray binaries (LMXB's; X1822-371, X1957+115, UW CrB, X1916-05 and...
