    TOI-257b (HD 19916b): a warm sub-saturn orbiting an evolved F-type star
    We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal was detected by TESS and confirmed to be of planetary origin based on radial velocity observations. An analysis of the TESS photometry, the MINERVA-Australis, FEROS, and HARPS radial

    TIC 168789840: A Sextuply Eclipsing Sextuple Star System
    We report the discovery of a sextuply eclipsing sextuple star system from TESS data, TIC 168789840, also known as TYC 7037-89-1, the first known sextuple system consisting of three eclipsing binaries. The target was observed in Sectors 4 and 5 during Cycle 1, with lightcurves extracted from TESS Full Frame Image data. It was also previously

    The WaZP galaxy cluster sample of the dark energy survey year 1
    We present a new (2+1)D galaxy cluster finder based on photometric redshifts called Wavelet Z Photometric (WaZP) applied to DES first year (Y1A1) data. The results are compared to clusters detected by the South Pole Telescope (SPT) survey and the redMaPPer cluster finder, the latter based on the same photometric data. WaZP searches for clusters in

    The plague of magnetic spots among the hot stars of globular clusters: a bridge between MS and WD stars
    I will report on our recent discovery of a wide-spread photometric variability among hot (~20,000 – 30,000 K) extreme horizontal branch (EHB) stars in Galactic globular clusters. The EHB variability is periodic, displaying single-wave, low-amplitude and ~2-50 days modulations. The variability cannot be ascribed to either binary evolution or

    The number of globular clusters around the iconic UDG DF44 is as expected for dwarf galaxies
    There is a growing consensus that the vast majority of ultradiffuse galaxies (UDGs) are dwarf galaxies. However, there remain a few UDGs that seem to be special in terms of their globular cluster (GC) systems. In particular, according to some authors, certain UDGs exhibit large GC populations when compared to expectations from their stellar (or
