We report the discovery of a unique object, BD+48 740, a lithium overabundant giant with A(Li) = 2.33 ± 0.04 (where A(Li) = log n Li/n H + 12), that exhibits...

We present new Ultraviolet and Visual Echelle Spectrograph (UVES) spectra of a sample of 15 cool unevolved stars with and without detected planetary companions...

The -beam asymmetry Σ in the photoproduction of negative pions on quasi-free neutrons in a deuterium target was measured at the Grenoble Anneau Accelerateur...

We present the analysis of data performed in order to identify the events of the γ + n → π- + p reaction obtained by bombarding a liquid Deuterium target with a...

The main objective of this work is to characterize relevant properties of the hot spots obtained in the interaction between ion beams of V23 + and a spherical...

Comet 21P/Giacobini-Zinner was observed from Nov. 8 to Dec. 10, 1998. Pre- and post-perihelion CCD images of the gas (CN, C2) and dust (green and red continua)...

Context. Gaia benchmark stars are selected to be calibration stars for different spectroscopic surveys. Very high-quality and homogeneous spectroscopic data for...

Context. Ground-based transit observations are affected by both telluric absorption and instrumental systematics, which can affect the final retrieved...

The OSIRIS-REx spacecraft encountered the asteroid (101955) Bennu on December 3, 2018, and has since acquired extensive data from the payload of scientific...
