We present the results of a comprehensive survey conducted among members of the Spanish Astronomical Society (Sociedad Española de Astronomía, SEA) to assess...

Context. The young massive cluster Westerlund 1 offers the promise of a grand laboratory for the study of high-mass star evolution, but its basic parameters are...

We report on the 323 hours of nearly uninterrupted time series photometric observations of the DBV star GD 358 acquired with the Whole Earth Telescope (WET)...

Context. The usual approach to classify the ionizing source using optical spectroscopy is based on the use of diagnostic diagrams that compare the relative...

Characterizing the structural properties of galaxies in high-redshift protoclusters is key to our understanding of the environmental effects on galaxy evolution...

We present a comparison between the observed galaxy stellar mass function and the one predicted from the De Lucia & Blaizot semi-analytic model applied to the...

We present a study aimed at understanding the physical phenomena underlying the formation and evolution of galaxies following a data-driven analysis of...

The Sun and other similar (solar-like) stars have an internal magnetic field that can emerge on the surface, forming features such as dark spots, which drive...

The low-mass X-ray binary 4U 0614+091 is a source of sporadic thermonuclear (type I) X-ray bursts. We find bursts with a wide variety of characteristics in...
