    The IACOB project. I. Rotational velocities in northern Galactic O- and early B-type stars revisited. The impact of other sources of line-broadening
    Context. Stellar rotation is an important parameter in the evolution of massive stars. Accurate and reliable measurements of projected rotational velocities in...
  • 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 spectroscopic database of galactic OB stars
    We present the IACOB spectroscopic database, the largest homogeneous database of high-resolution, high signal-to-noise ratio spectra of Northern Galactic OB...
