Context. Recent observational programs are providing a global view of the Milky Way bulge that serves as a template for detailed comparison with models and extragalactic bulges. A number of surveys (VVV, GIBS, GES, ARGOS, BRAVA, APOGEE) are producing comprehensive and detailed extinction, metallicity, kinematics, and stellar density maps of the

Since the start of the Wide-angle Search for Planets (WASP) program, more than 160 transiting exoplanets have been discovered in the WASP data. In the past, possible transit-like events identified by the WASP pipeline have been vetted by human inspection to eliminate false alarms and obvious false positives. The goal of this paper is to assess the

Las manchas solares, regiones oscuras y frías de la superficie solar, se llevan observando desde hace miles de años. Estas estructuras son grandes concentraciones de campo magnético que inhiben la convección, haciéndolas más frías y oscuras que sus alrededores (Hale 1908). Nos encontramos en un momento especialmente óptimo para el estudio en largas

LiLiMaRlin is a library of libraries of massive-star high-resolution optical spectra built by collecting data from [a] our spectroscopic surveys (OWN, IACOB. NoMaDS, and CAFÉ-BEANS) and programs and [b] searches in public archives. The current version has 18 077 spectra of 1665 stars obtained with seven different telescopes (HET 9.2 m, NOT 2.56 m

Planet host stars with well-constrained ages provide a rare window to the time domain of planet formation and evolution. The NASA K2 mission has enabled the discovery of the vast majority of known planets transiting stars in clusters, providing a valuable sample of planets with known ages and radii. We present the discovery of two planets

We consider magnetohydrodynamics models and observations of transverse oscillations in prominence threads to obtain information on their physical properties such as the magnetic field strength, the plasma density, or the length. We further compare between short and long thread limits in period ratio models and compute the relative plausibility of
