Over the last decade, astrophysical observations of neutron stars — both as isolated and binary sources — have paved the way for a deeper understanding of the structure and dynamics of matter beyond nuclear saturation density. The mapping between astrophysical observations and models of dense matter based on microscopic dynamics has been poorly investigated so far. However, the increased accuracy of present and forthcoming observations may be instrumental in resolving the degeneracy between the predictions of different equations of state. Astrophysical and laboratory probes have the potential to paint to a new coherent picture of nuclear matter — and, more generally, strong interactions — over the widest range of densities occurring in the Universe. This book provides a self-contained account of neutron star properties, microscopic nuclear dynamics and the recent observational developments in multimessenger astronomy. It also discusses the unprecedented possibilities to shed light on long standing and fundamental issues, such as the validity of the description of matter in terms of pointlike baryons and leptons and the appearance of deconfined quarks in the high density regime.

It will be of interest to researchers and advanced PhD students working in the fields of Astrophysics, Gravitational Physics, Nuclear Physics and Particle Physics.

Questo libro si propone di fornire un''introduzione, allo stesso tempo accessibile e completa, alle stelle compatte. Dopo una prima parte dedicata alla fisica delle nane bianche, nella parte centrale del volume vengono analizzate la struttura e la dinamica delle stelle di neutroni. Particolare attenzione è rivolta ai modelli utilizzati per la descrizione della materia stellare a livello microscopico. Questi modelli sono altamente multidisciplinari, in quanto abbracciano campi di ricerca che vanno dalla fisica nucleare e delle particelle elementari alla fisica della materia condensata all''astrofisica. Tutti gli argomenti sono trattati con un approccio pedagogico, facendo riferimento allo sviluppo storico delle osservazioni astronomiche e degli studi teorici. Ampio spazio è dedicato alla discussione dell''impatto dei risultati sperimentali più recenti, come la rivelazione di onde gravitazionali, e dei dati senza precedenti che saranno disponibili nella nascente era dell''astronomia multimessaggera. Questo volume vuole offrire agli studenti di dottorato in fisica ed astrofisica delle solide basi per la loro futura carriera scientifica. I ricercatori già impegnati nei campi della fisica nucleare e delle particelle, così come nell''astrofisica a nella fisica gravitazionale, lo troveranno un utile strumento di consultazione.
