PSR J1437-5959 has period P = 61 ms, characteristic age tau{sub c}=P/(2P-dot)=114 kyr, and spin-down luminosity E-dot=1.4 x 10{sup 36} erg s{sup -1}.The alkenone temperature at Station 5 before 20 kyr B.P. ranged from 8° to 12°C, and the cold-water mass corresponding to subarctic water covered the surface of the modern KBF area during the LGM. During 20-30 kyr B.P., the average alkenone temperature was calculated as 7.5°C at Station 8s, 9.6°C at Station 5, and 12.5°C at Station 6.

• The soft g-ray pulsar population is younger and more energetic than the LAT one • Soft g-ray pulsars reach max. luminosity at MeV energies, the LAT pulsars do so in GeV range • The large majority of the soft g-ray pulsars has single broad (asymmetric/ structured) pulses contrary to the LAT pulsars, showing mainly double pulses • Soft ...PSR J0250+5854: A Record-Setting Slow Spinning Radio Pulsar.

Old (τ 10 6 years) RPPs have diminished spin-down powers ( erg s −1) and X-ray luminosities. This …

In this study, we have carried out paleointensity experiments on 918 specimens spanning the last ∼7 kyr, including pottery fragments, baked clay and slag, collected from Shandong, Liaoning, Zhejiang and Hebei Provinces in China. Approximately half of the specimens yielded results that passed strict data selection criteria and give high-fidelity paleointensities.The velocity and characteristic age of PSR J1825-1446 make it incompatible with SNR G016.8-01.1. There are no clear OB associations or SNRs crossing the past trajectory of PSR J1825-1446. We estimate the age of the pulsar to be 80-245 kyr, which is compatible with its characteristic age.

sks dkhtrwmadr Nov 18, 2021 · The SNR produced by the birth supernova of PSR J1734$-$3333 could have already faded to undetectable brightness, for which estimates suggest timescales of $10$-$100$ kyr. This and other considerations lead us to conclude that the pulsar is possibly older than $45$-$100$ kyr.SNR ∼1-7 kyr). PSR J1844−0256 was discovered in a search of AXP AX J1845−0258. Its P = 273 ms and DM = 820 pc cm−3 with a large scattering tail (τ scat ∼40 ms).
