This object has an extraordinarily long spin period, ~5 hour, attributed to the neutron star (NS) rotation, making 4U 1954+31 the slowest-rotating accreting NS binary. It raises a question about its binary evolution, since a slowly rotating NS orbiting an M-type giant is quite unique. As to its large variability, the popular clumpy wind model has not yet become a smoking-gun, and we propose an alternative hypothesis that the NS is a magnetar descendent captured by an M-type giant in their closer encounter. Known X-ray properties of 4U~1954+31 will be revisited in a view of gated accretion onto the strongly magnetized NS. A 60 ks Suzaku observation can examine these scenarios. | GALACTIC POINT SOURCES | 4 | B | TERUAKI ENOTO | USA | 6 | AO6 | THE SLOWEST ROTATING PULSAR 4U 1954+31 | XIS | Y | https://data.darts.isas.jaxa.jp/pub/suzaku/ver3.0/406046010/ | Quick Look |
