Titolo: | The accretion rate and minimum spin period of accreting pulsars | Autori: | BONANNO, Alfio Maurizio Urpin, V. |
Data pubblicazione: | 2015 | Rivista: | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY | Numero: | 451 | Fascicolo: | 2 | Da pagina:: | 2117 | Abstract: | We consider combined rotational, magnetic, and thermal evolution of the neutron star during the accretion phase in a binary system. A rapid accretion-driven decay of the magnetic field decreases substantially the efficiency of angular momentum transfer. As a result, the neutron star cannot spin-up to periods shorter than some limiting value even if accretion is very long and accretion rate is high. The proposed mechanism can explain a discrepancy between the shortest detected period and minimal possible spin period of neutron stars. | Acknowledgments: | We would like to thank Dany Page for kindly providing us with the mean-field EOS used in the calculation. | URI: | http://hdl.handle.net/20.500.12386/24046 | URL: | https://academic.oup.com/mnras/article/451/2/2117/1749857 | ISSN: | 0035-8711 | DOI: | 10.1093/mnras/stv1112 | Bibcode ADS: | 2015MNRAS.451.2117B | Fulltext: | open |
