    Ca II and Hα flaring M dwarfs detected with multi-filter photometry
    Context. Understanding and characterising the magnetic activity of M dwarfs is of paramount importance in the search for Earth-like exoplanets orbiting them...

    Calcium triplet metallicity calibration for stars in the Galactic bulge
    Aims: We present a new calibration of the calcium II triplet equivalent widths versus [Fe/H], constructed upon K giant stars in the Galactic bulge. This...

    CALIFA, the Calar Alto Legacy Integral Field Area survey. I. Survey presentation
    The final product of galaxy evolution through cosmic time is the population of galaxies in the local universe. These galaxies are also those that can be studied...

    Can Jupiters be found by monitoring Galactic bulge microlensing events from northern sites?
    In 1998 the EXPORT team monitored microlensing event light curves using a charge-coupled device (CCD) camera on the IACQ4 0.8-m telescope on Tenerife to...

    Can spicules be detected at disc centre in broad-band Ca ii H filter imaging data?
    Context. Recently, a possible identification of type II spicules in broad-band (full-width at half-maximum (FWHM) of ~0.3 nm) filter imaging data in Ca ii H on...

    Can we detect the stellar differential rotation of WASP-7 through the Rossiter-McLaughlin observations?
    The Rossiter-McLaughlin (RM) effect is the radial velocity signal generated when an object transits a rotating star. Stars rotate differentially and this...
