    The IACOB project. II. On the scatter of O-dwarf spectral type - effective temperature calibrations
    Context. We are now in an era of large spectroscopic surveys of OB-type stars. Quantitative spectroscopic analysis of these modern datasets is enabling us to...
  • Publication
    The IACOB project. IV. New predictions for high-degree non-radial mode instability domains in massive stars and their connection with macroturbulent broadening
    Context. Asteroseismology is a powerful tool to access the internal structure of stars. Apart from the important impact of theoretical developments, progress in...
  • Publication
    The IACOB project. IX. Building a modern empirical database of Galactic O9 - B9 supergiants: Sample selection, description, and completeness
    Context. Blue supergiants (BSGs) are key objects for studying the intermediate phases of massive star evolution because they are very useful to constrain...
  • Publication
    The IACOB project. V. Spectroscopic parameters of the O-type stars in the modern grid of standards for spectral classification
    Context. The IACOB and OWN surveys are two ambitious, complementary observational projects which have made available a large multi-epoch spectroscopic database...
  • Publication
    The IACOB project. VI. On the elusive detection of massive O-type stars close to the ZAMS
    Context. The apparent lack of massive O-type stars near the zero-age main sequence, or ZAMS (at ages <2 Myr), is a topic that has been widely discussed in the...
  • Publication
    The IACOB project. VII. The rotational properties of Galactic massive O-type stars revisited
    Context. Stellar rotation is of key importance in the formation process, the evolution, and the final fate of massive stars. Aims: We perform a reassessment of...
  • Publication
    The IACOB project. VIII. Searching for empirical signatures of binarity in fast-rotating O-type stars
    Context. The empirical distribution of projected rotational velocities (v sin i) in massive O-type stars is characterised by a dominant slow velocity component...
  • Publication
    The IACOB project. X. Large-scale quantitative spectroscopic analysis of Galactic luminous blue stars
    Context. Blue supergiants (BSGs) are key objects for understanding the evolution of massive stars, which play a crucial role in the evolution of galaxies...
  • Publication
    The IACOB project. XI. No increase in mass-loss rates over the bistability region
    The properties of blue supergiants are key for constraining the end of the main sequence (MS) of massive stars. Whether the observed drop in the relative number...
