A.; Silva Farfán, Javier Ignacio; Camacho Iñiguez, E.; Galbany, L. (IOP, 2021)
      We present a real-time stamp classifier of astronomical events for the Automatic Learning for the Rapid Classification of Events broker, ALeRCE. The classifier is based on a convolutional neural network, trained on alerts ...
    • Is a binary fraction-age relation responsible for the lack of EHB binaries in globular clusters? 
      Moni Bidin, Christian; Catelan, M.; Altmann, Martin (EDP SCIENCES S A, 2008-03)
      Context. The recently-discovered lack of close binaries, among extreme horizontal branch (EHB) stars in Galactic globular clusters, has thus far constituted a major puzzle, in view of the fact that blue subdwarf stars – ...
