BOOTES-IR: Near IR follow-up GRB observations by a robotic system
“BOOTES-IR" is the extension of the BOOTES experiment, which operates in Southern Spain since 1998, to the near IR (NIR). The goal is to follow up the early...
Borderline hyperbolic comet C/2021 O3 (PANSTARRS) was fading as it approached the Sun
We present an observational and numerical study of the borderline hyperbolic comet C/2021 O3 (PANSTARRS) performed during its recent passage through the inner...
Boron Abundances in Early B Dwarfs of the Galactic Open Cluster NGC 3293
New boron abundances or upper limits have been determined for eight early B stars in the young Galactic open cluster NGC 3293, using UV spectra obtained by the...
Boron depletion in Galactic early B-type stars reveals two different main sequence star populations
Context. The evolution and fate of massive stars are thought to be affected by rotationally induced internal mixing. The surface boron abundance is a sensitive...
We have observed the B I 2497 A line to derive the boron abundances of two very metal-poor stars selected to help in tracing the origin and evolution of this...
Bose-Einstein correlations in p p , p Pb , and PbPb collisions at √{sN N}=0.9 -7 TeV
Quantum-statistical (Bose-Einstein) two-particle correlations are measured in p p collisions at √{s }=0.9 , 2.76, and 7 TeV, as well as in p Pb and peripheral...
Context. Galaxy superclusters are the largest systems in the Universe that can give us information about the formation and evolution of the cosmic web. Aims: We...
