The resulting age of the system is between 10 and 30 kyr. For a 10 kpc distance (also consistent with the X-ray absorption) the 2-10 keV X-ray luminosities of the putative pulsar and nebula are L PSR ~ 1.3 × 10 33 d 2 10 kpc erg s-1 and L PWN ~ 3.9 × 10 33 d 2 10 erg s-1 (d 10 = d/10 kpc).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 J1833-1034, with spin period P=61.8 ms and dispersion measure 169 cm -3 pc, is very faint, with pulse-averaged flux density of ~70 μJy at a frequency of 1.4 GHz, and was first detected in a deep search with the Parkes telescope. ...

Speedy and friends best of the week. The Sp33dy: https://www.twitch.tv/kyr_sp33dyAll the friends:https://www.twitch.tv/sidearms4reasonhttps://www.twitch.tv/t...We report the analysis of the first deep optical observations of three isolated γ-ray pulsars detected by the Fermi Gamma-ray Space Telescope: the radio-loud PSR J0248+6021 and PSR J0631+1036, and the radio-quiet PSR J0633+0632. The latter has also been detected in the X-rays. The pulsars are very similar in their spin-down age (τ ∼ 40-60 kyr), spin-down energy (E˙∼1035 erg s−1 ...c > 220 kyr. The latter is much longer than the SNR age, indicating that PSR J0821−4300 was born spinning near its present period. Its properties are remarkably similar to those of the two other known CCO pulsars, demonstrating the existence of a class of neutron stars born with weak magnetic fields related to a slow original spin.We report the discovery of PSR J1906+0746, a young 144 ms pulsar in a highly relativistic 3.98 hr orbit with an eccentricity of 0.085 and expected gravitational wave coalescence time of ~300 Myr. The new pulsar was found during precursor survey observations with the Arecibo 1.4 GHz feed array system and retrospectively detected in the Parkes Multibeam plane pulsar survey data. From radio ...
This and other considerations lead us to conclude that the pulsar is possibly older than 45 − 100 kyr. PSR J1734−3333 is a pulsar with rotational properties that place it between standard ...Climate variability over the past 800,000 years has long been described as being dominated by ~100-kyr glacial cycles, and researchers have debated whether these glacial cycles were driven by ...The second pulsar, PSR J1814-1744, has P=3.975 s and P=7.4×10-13.

Source Position: From Aharonian et al. (2021):Mar 2, 2022 · 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 nine pulsars have spin frequencies between 3 and 12 Hz, and characteristic ages ranging from 17 kyr to 3 Myr. Two of them, PSRs J1803-2149 and J2111+ 4606, are young and energetic Galactic-plane pulsars (spin-down power above 6 × 10 35 erg s -1 and ages below 100 kyr). ... > 10°). PSR J0106+4855 has the largest characteristic age (3 Myr ...The pulsar's spin-down rate implies a rotation-powered luminosity E-dot = 1.2x10{sup 38} erg s{sup -1}, a surface dipole magnetic field strength B{sub s} = 1.0 x 10{sup 12} G, and a characteristic age of 8.9 kyr. PSR J2022+3842 is thus the second-most energetic Galactic pulsar known, after the Crab pulsar, as well as the most rapidly rotating ...The timing solution, reported by Levin et al. , implies a very high surface magnetic field of B≈ 2.8 × 10 14 G and a characteristic age of τ c ≈ 4 kyr. PSR J1622-4950 has a flat radio spectrum and a highly variable flux density and pulse profile [8 - 10, 16, 89], which is similar to other radio magnetars.
