IACOB is an ambitious long-term observational project which is contributing to the so-called new era of investigation of massive stars by concentrating on Galactic OB stars. More specifically, the main scientific goal of the project is to provide a complete empirical overview of the physical properties of a statistically significant sample of Galactic OB stars. In particular, the ultimate...

59. On the s-elements content of the Milky Way as revealed by Gaia/DR3 data

Understanding the formation and evolution history of the Milky Way is still quite challenging. Combining kinematic and dynamical studies together with the chemical analysis of large number of stars allows us to well characterize the Galactic stellar populations and, hence, unveil their formation histories. Especially, abundances of neutron-capture elements are particularly important to...

61. Classical Cepheids as Distance Indicators and Stellar Population Tracers in the Gaia Era (Invited)

Modeling of radially pulsating stars, specifically Classical Cepheids, is fundamental to constrain the physical properties of these stars and their role as stellar population tracers, as well as to calibrate the extragalactic distance scale. In particular, the investigation of the dependence of their predicted properties on the various physical and numerical assumptions can help understand...
