The IACOB spectroscopic database: recent updates and rst data release

Abstract The IACOB project is an ambitious long-term project which is contributing to step forwardin our knowledge about the physical properties and evolution of Galactic massive stars. Theproject aims at building a large database of high-resolution, multi-epoch, spectra of GalacticOB stars, and the scienti c exploitation of the database using state-of-the-art models andtechniques. In this proceeding, we summarize the latest updates of the IACOB spectroscopicdatabase and highlight some of the rst scienti c results from the IACOB project; we alsoannounce the rst data release and the rst public version of the iacob-broad tool for theline-broadening characterization of OB-type spectra. 1 Introduction Massive stars have been many times claimed as Cosmic Engines and Gifts of Nature for thestudy of the Universe, from the Solar neighbourhood to the large-z Universe. The completeunderstanding of the physical properties and evolution of massive stars (and their interplaywith the interstellar medium) is crucial for many elds of Astrophysics and, ultimately, to
