Pulsars that were discovered before 1993 tend to retain their B names rather than use their J names (e.g. PSR J1921+2153 is more commonly known as PSR B1919+21). Recently discovered pulsars only have a J name (e.g. PSR J0437−4715). All pulsars have a J name that provides more precise coordinates of its location in the sky. [38]
The most dynamic feature in the inner part of the nebula is the point where the pulsar's equatorial wind slams into the surrounding nebula, forming a termination shock. The shape and position of this feature shifts rapidly, with the equatorial wind appearing as a series of wisp-like features that steepen, brighten, then fade as they move away ...
An intermediate-mass binary pulsar (IMBP) is a pulsar-white dwarf binary system with a relatively long spin period of around 10–200 ms consisting of a white dwarf with a relatively high mass of approximately . [7] The spin periods, magnetic field strengths, and orbital eccentricities of IMBPs are significantly larger than those of low mass binary pulsars (LMBPs). [7]
Most observed magnetars rotate once every two to ten seconds, [8] whereas typical neutron stars, observed as radio pulsars, rotate one to ten times per second. [9] A magnetar's magnetic field gives rise to very strong and characteristic bursts of X-rays and gamma rays.
Millisecond pulsars have been detected in radio, X-ray, and gamma ray portions of the electromagnetic spectrum. The leading hypothesis for the origin of millisecond pulsars is that they are old, rapidly rotating neutron stars that have been spun up or "recycled" through accretion of matter from a companion star in a close binary system.
Authorities have identified the woman who burned to death after she was set on fire inside a New York City subway train as 57-year-old Debrina Kawam.
Having her dad's scent around helps this Golden Retriever relax for her daily naps, so she clearly sees him as a core part of her pack. She knows that all is well when Dad is home, so at least ...
Gleaton Jones, a former walk-on running back for the University of Georgia Bulldogs football team, has died at 21 following a car crash this week. Jones died on Friday, Dec. 13, according to an ...
