The distances and the spin-down luminosities of these pulsars are listed in Table 1. There are some uncertainties about the distance of PSR J0855−4644 since no accurate parallax measurements are available. The dispersion measure gives a distance of ∼ 6For instance, Geminga, PSR B0656+14 and PSR B1055−52 (τ ~ a few 100 kyr), and PSR J0538+2817 (τ = 30 kyr) show such asymmetric pulse profiles (e.g., De Luca et al. 2005; Zavlin & Pavlov 2004b; McGowan et al. 2003; Pavlov et al. 2002). Old (τ 10 6 years) RPPs have diminished spin-down powers ( erg s −1) and X-ray luminosities. This …The characteristic age of PSR J1734−3333 estimated from its current spin down rate implies that it is a young pulsar (τ c = 8.1 kyr). However, the time derivative of its spin-down rate differs markedly from that assumed for normal radio pulsars, meaning its actual age is uncertain.The Center for Constitutional Rights, founded in 1966, based in New York, is a progressive non-profit legal advocacy organization.
