We present an observational and numerical study of the borderline hyperbolic comet C/2021 O3 (PANSTARRS) performed during its recent passage through the inner Solar system. Our observations were carried out at OASI and SOAR between 2021 October and 2022 January, and reveal a low level of activity relative to which was measured for other long-period

Aims: We aim to compute the binary fraction of "classical" dwarf spheroidal galaxies (dSphs) that are satellites of the Milky Way (MW). This value can offer insights into the binary fraction in environments that are less dense and more metal-poor than our own galaxy. Additionally, knowledge of the binary fraction in dwarf galaxies is important with

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 pure precompressed deuterium-tritium plasmas in the field of ion fast ignition scheme. In particular, we focus our analysis on the determination of the length, average temperature and maximum

The systematic discovery of outflows in the optical spectra of low-mass X-ray binaries opened a new avenue for the study of the outburst evolution in these extreme systems. However, the efficient detection of such features in a continuously growing data base requires the development of new analysis techniques with a particular focus on scalability

An analytical model for the determination of the spatial temperature field of a deuterium-tritium plasma heated by a fast and monoenergetic fully stripped ion beam is presented. This analytical model provides relevant hot spot properties in good agreement respect those generated by a numerical model for fast monoenergetic ion beams. The model is
