摘 要:Recently another long period radio pulsar GPM J1839-10 has been reported,similar to GLEAM-X ***,the energy budget and rotational evolution of long period radio pulsars had been *** time,the death line and pulse width for neutron star and white dwarf pulsars are *** pulse width is included as the second criterion for neutron star and white dwarf *** is found that:(1)PSR J0250+5854 and PSR J0901-4046 *** be normal radio *** have narrow pulse width and they lie near the radio emission death line.(2)The two long period radio pulsars GLEAM-X J162759.5-523504.3 and GPM J1839-10 are unlikely to be normal radio *** possible pulse width is relatively *** lie far below the fiducial death line on the P-P^(·)diagram.(3)GLEAM-X J162759.5-523504.3 and GPM J1839-10 may be magnetars or white dwarf radio *** present,there are many parameters and uncertainties in both of these possibilities.
