HIGHLIGHTS

  • who: Clementini Gisella et al. from the INAF, Osservatorio Astronomico di Bologna, Via Gobetti, Bologna, Italy Department of Astronomy, University of Geneva, Chdes Maillettes, Versoix, Switzerland have published the research work: Gaia’s Cepheids and RR Lyrae stars and luminosity calibrations based on Tycho-Gaia Astrometric Solution, in the Journal: (JOURNAL)
  • what: The TGAS-based luminosity calibrations presented in this study have to be considered pre- Wide-Field Variability Surveys: A 21st Century Perspective DOI: 10.1051/ epjconf/201715202003 liminary and to be superseded by new more accurate relations calibrated on Gaia-only parallaxes that . . .
