Black-holes and neutron stars are extremely important astrophysical objects, which become unique laboratories of extreme physics when found within X-ray binaries. Their study provides high-impact results, which are relevant for many astrophysics and fundamental physics areas. Our project target fundamental properties of both the accretion process

Accreting black-holes and neutron stars in X-ray binaries provide an ideal laboratory for exploring the physics of compact objects, yielding not only confirmation of the existence of stellar-mass black holes via dynamical mass measurements, but also the best opportunity for probing high-gravity environments and the physics of accretion; the most

BRIDGES main aim is the study of physical properties of the atmospheres ultracool dwarfs andexoplanets, modelling their spectra and comparison them with observations to get their physicalparameters and study possible biomarkers of rocky planets in the habitable zones. The specific objectives planned in the context of BRIDGES are the following: SO1)
