• EL FORMALISMO PERTURBATIVO EN LA EVOLUCION NO LINEAL DE ESTRUCTURAS COSMOLOGICAS.

Hay dos formalismos para el estudio de la evolución de estructuras a gran escala desde un punto de vista analítico: el Lagrangiano y el Euleriano. Los buenos resultados dados por el primero y lo farragoso de la presentación usual del segundo han hecho que este último haya recibido escasa atención. En este trabajo se muestra una presentación más

• Spectroscopic characterization of the known O-star population in Cygnus OB2. Evidence of multiple star-forming bursts

Context. Cygnus OB2 provides a unique insight into the high-mass stellar content in one of the largest groups of young massive stars in our Galaxy. Although several studies of its massive population have been carried out over the last decades, an extensive spectroscopic study of the whole known O-star population in the association is still lacking

• A giant planet candidate transiting a white dwarf

Astronomers have discovered thousands of planets outside the Solar System1, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During the red giant phase, any close-orbiting planets will be engulfed by the star2, but more distant planets can survive this phase and remain in orbit around the white

• A quantitative demonstration that stellar feedback locally regulates galaxy growth

We have applied stellar population synthesis to 500-pc-sized regions in a sample of 102 galaxy discs observed with the MUSE spectrograph. We derived the star formation history and analyse specifically the 'recent' ( $20\,\rm {Myr}$ ) and 'past' ( $570\,\rm {Myr}$ ) age bins. Using a star formation self-regulator model, we can derive local mass

• How many components? Quantifying the complexity of the metallicity distribution in the Milky Way bulge with APOGEE

We use data of ∼13-=000 stars from the Sloan Digital Sky Survey/Apache Point Observatory Galactic Evolution Experiment survey to study the shape of the bulge metallicity distribution function (MDF) within the region |ℓ| ≤ 11° and |b| ≤ 13°, and spatially constrained to RGC ≤ 3.5 kpc. We apply Gaussian mixture modelling and non-negative matrix
