PublicaciónThe VLT-FLAMES Tarantula Survey. XXIX. Massive star formation in the local 30 Doradus starburst
The 30 Doradus (30 Dor) nebula in the Large Magellanic Cloud (LMC) is the brightest HII region in the Local Group and a prototype starburst similar to those...

PublicaciónThe VLT-FLAMES Tarantula Survey. XXV. Surface nitrogen abundances of O-type giants and supergiants
Context. Theoretically, rotation-induced chemical mixing in massive stars has far reaching evolutionary consequences, affecting the sequence of morphological...

PublicaciónThe VLT-FLAMES Tarantula Survey. XXVIII. Nitrogen abundances for apparently single dwarf and giant B-type stars with small projected rotational velocities
Previous analyses of the spectra of OB-type stars in the Magellanic Clouds have identified targets with low projected rotational velocities and relatively high...

PublicaciónThe VLT-FLAMES Tarantula Survey. XXXI. Radial velocities and multiplicity constraints of red supergiant stars in 30 Doradus
Aims: The incidence of multiplicity in cool, luminous massive stars is relatively unknown compared to their hotter counterparts. In this work we present radial...

PublicaciónThe young stellar population of IC 1613. II. Physical properties of OB associations
Context. To understand the structure and evolution of massive stars, systematic surveys of the Local Group galaxies have been undertaken, to find these objects...

CharlaThinking about stellar populations modeling
The basis of stellar population modeling was established around 40 years ago somehow optimized to the technical facilities and observational data available at...

PublicaciónThree supernova shells around a young M33 star cluster
Using a specialized technique sensitive to the presence of expanding ionized gas, we have detected a set of three concentric expanding shells in an H II region...

PublicaciónTop-heavy integrated galactic stellar initial mass functions in starbursts
Star formation rates (SFRs) larger than 1000 M&sun; yr-1 are observed in extreme starbursts. This leads to the formation of star clusters with masses >106 M&sun...
