Description
We present merger models suggesting that bulge growth via accretion of dense satellites generates two of the observed trends of galaxies along the Hubble sequence, namely the increase of Sersic index toward more massive bulges, and the appearance of a thick disk with higher scale length than that of the thin disk. We argue that bulges with exponential surface brightness profiles cannot have grown significantly from collisionless satellite accretion.

    On the elusive detection of O-type stars close to the ZAMS: the empirical birthline of massive stars
    In this contribution we present the results from a 1 homogeneous quantitative spectroscopic analysis of ∼400 Galactic O-type stars targeted by the IACOB and OWN surveys. The ultimate objective is to perform a modern reassessment of one of the long-standing problems in the field of massive stars: the elusive detection of mid O-type stars close to

    The impact of binary interaction on the main-sequence morphology of young star clusters
    Since massive stars form preferentially as members of close binary systems, we use dense grids of detailed binary evolution models to explore how binary evolution shapes the main-sequence morphology of young star clusters. We propose that binary mergers might be the origin of the blue main sequence stars in young star clusters. Our results imply
