CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe evolution of young and hot white dwarfs (WDs) is largely dominated by the neutrino energy losses. Thus these stars provide a natural laboratory for testing the theoretical efficiency of the neutrino production processes, standard and not-standard. The present work is focussed on the not-standard energy losses due to a not-zero neutrino magnetic moment. By relying on very recent WD models we find an upper limit for the neutrino magnetic moment of approximate to 5.10(-12) mu(B).
