We present the abundances of magnesium (Mg) and silicon (Si) for 314 dwarf stars with spectral types in the interval K7.0–M5.5 (T eff range ≈ 4200–3050 K)...

Context. Radial velocity (RV) jitter represents an intrinsic limitation on the precision of Doppler searches for exoplanets that can originate from both...

Context. Current exoplanet surveys are focused on detecting small exoplanets orbiting in the liquid-water habitable zones of their host stars. Despite recent...

We present ~47,000 periodic variables found during the analysis of 5.4 million variable star candidates within a 20,000 deg2 region covered by the Catalina...

We present the analysis using pyPipe3D of a sample of 208 galaxies from the CAVITY project , that includes: (i) a description of the processes performed by this...

The Universe is shaped as a web-like structure, formed by clusters, filaments, and walls that leave large low number-density volumes in between named voids...

Type 2 active galactic nuclei (AGN) are by definition nuclei in which the broad-line region and continuum light are hidden at optical/UV wavelengths by dust...

Wide-field searches for transiting extrasolar giant planets face the difficult challenge of separating true transit events from the numerous false positives...

Context. Hot Jupiters are giant planets subject to intense stellar radiation. The physical and chemical properties of their atmosphere make them the most...
