Five fitted lines in Figure 7 represent the evolution paths of the pulsar in the context of dipole magnetic field decay, and the arrows represent the spin-down evolution directions with different initial spin period in the next 100 kyr. PSR J1634−4631 would be placed in the top left region of the diagram at its birth.

The thresholds are 10 c s −1 for PSR J0537−6910, 4.5 c s −1 for PSR J1412+7922, and 5 c s −1 for PSR J1849−0001, and they are the same as previously used in Ho et al. for PSR J0537−6910 and in Bogdanov et al. for PSR J1412+7922 and PSR J1849−0001. Using these filtering criteria, we obtain clean data for pulse timing analysis.56033.3600, PSR J1826 1256 has a characteristic age of 14.4 kyr, spin-down luminosity E_ of 3:6 1036 erg s 1, and surface magnetic eld B= 3:7 1012 G (Kargaltsev et al.2017).

Abstract: The characteristic age of PSR J1734$-$3333 estimated from its current spin down rate implies that it is a young pulsar ($\tau_c<10$ kyr). But the time derivative of its spin down rate differs markedly from that assumed for normal radio pulsars, meaning its actual age is uncertain.Can you believe you're watching the playlist of the 9x purge champions?Select Start Record.

The survey has so far resulted in the discovery of 15 radio pulsars, including a pulsar with a characteristic age of ∼18 kyr, PSR J2004+3429, and a highly eccentric, binary millisecond pulsar, PSR J1946+3417.PSR J1048-5832 is a Vela-like (P=123.6 ms; tau~20.3 kyr) gamma-ray pulsar detected by Fermi, at a distance of ~2.7 kpc and with a rotational energy loss rate dot{E}_{SD} ~2 x 10^{36} erg/s. The PSR J1048-5832 field has been observed with the VLT in the V and R bands. We used these data to determine the colour of the object detected closest to the Chandra position (Star D) and confirm that it ...

[5] Among others, a few papers attempted to relate the ∼100-kyr period directly to one of the astronomical parameters. Wigley suggested a nonlinear response to precession (beating the two main frequencies of e sin : (1/19-1/23) equals ∼ 1/100). Rial related the sawtooth shape of late Pleistocene paleoclimate records to the first derivative of e. Liu included the frequency variations of ...The SNR produced by the birth supernova of PSR J1734−3333 could have already faded to undetectable brightness, estimates of which suggest timescales of 10 − 100 kyr.
