The atnf pulsar catalogue
WebMay 11, 2024 · The majority of pulsars have spin periods between ~0.1 and ~4 seconds. The longest period radio pulsar, PSR J2144-3933, has a period of 8.5 seconds. Such pulsars typically have slow down rates of ~10 -14 s/s. Another group of pulsars, known as the "millisecond pulsars", appear in the bottom left-hand part of the diagram. WebThe ATNF Pulsar Catalog. The number of known pulsars has significantly increased over the past few years. We have searched the literature to find papers announcing the discovery of pulsars or giving improved parameters for them. Data from the papers have been entered into a new pulsar catalog that can be accessed via a web interface or from the ...

WebFast radio bursts (FRBs) were discovered only in 2007. However, the number of known events and sources of repeating bursts grows very rapidly. In the near future, the number of events will be ≳104 and the number of repeaters ≳100. Presently, there is a consensus that most of the sources of FRBs might be neutron stars (NSs) with large …
