This Plan aims to study the populations and classes of neutron stars and black holes. We propose to investigate the cosmic evolution of the population, the objects resulting from the mergers of NSs detected in GW and X-gamma bands: what is their distribution of final masses, both for remaining NSs (if any) and BHs. We will help to establish the origin of the merging binary systems, the ev…
This Plan aims to advance in the knowledge of the populations and structure of neutron stars. We propose to investigate the objects resulting from the mergers (fusions) of NSs detected in gravitational waves and electromagnetic frequencies: their final mass distribution, both for NSs remnants (if any) and BHs. We will help to establish the origin of the merging binary systems, their evolu…
The exact conditions under which the fundamental degrees of freedom of strongly interacting matter, quarks, and gluons, described by Quantum Chromodynamics (QCD), can be realized in Nature is still an open question. They certainly played a fundamental role in the very first instants of the Universe, being the quarks and gluons confined into hadrons when the temperature of the Universe dro…

The determination of masses and number of compact objects in the galaxy is possible using traditional techniques based on Kepler's Laws, but also on new methodologies that have expanded the sample of neutron stars and black holes. These include Shapiro delay, spectrophotometry, microlensing and others. As a result, the masses of some 120 neutron stars (NSs) and 40 black holes (BNs) have b…
We know little about DNS as a subset of the neutron star population in general. The formation channel hypothesized to produce the systems that were known (Fig. 2, left [3]) has a massive giant and another Main Sequence companion in a stable mass transfer process that brings the system into a common envelope after the more massive one explodes as a supernova and forms the first neutron sta…
Due to the detection of gravitational waves from the coalescenceof neutron stars, new possibilities for the study of these objects appeared. Not only by the analysis of gravitational waves which already provide limits for mass, radius and stiffness, but also from the study of its luminous counterpart, which carries information about the nucleo synthesis of heavy elements such as gold and …
The plan aims identify the presence of exotic mater in stellar interiors. For this we must execute the necessary calculations to interpret the binding energy emitted in neutrinos (by SN1987A and other events) and analyze its viability in terms of the collapse theories with and without hadron-quark phase transitions, in addition to study the relation of the evolutionary histories of the b…
The main objective of this plan is to model extraterrestrial environments, taking into account radiation as a factor influencing the origin, evolution and development of life inside or outside the Solar System. This plan involves both theoretical and experimental work. The first part involves theoretical modeling of the potential effects of radiation over the biosphere of terrestrial (pri…

The main goal of this research project is to achieve expertise in numerical methods to study and simulate in full general relativity high-energy astrophysical phenomena relative to neutron stars in X-ray binary systems. This will lead to a better understanding of the accretion flows onto the compact star and potentially, a new way to constrain its properties and to learn about its equatio…
