The pulsar was discovered in 2024 using the MeerKAT radio telescope. [63] M62H has a rotational period of 3.70 milliseconds, meaning it completes 270 rotations per second (270 Hz). [65] Its planetary companion has a minimum mass of 2.5 M J and a median mass of 2.83 M J, assuming a mass of 1.4 M ☉ for the pulsar. Its minimum density is of 11 g ...
This kind of object is the only place where the behavior of matter at nuclear density can be observed (though not directly). Also, millisecond pulsars have allowed a test of general relativity in conditions of an intense gravitational field.
Also in 2016, Quizlet launched "Quizlet Live", a real-time online matching game where teams compete to answer all 12 questions correctly without an incorrect answer along the way. [15] In 2017, Quizlet created a premium offering called "Quizlet Go" (later renamed "Quizlet Plus"), with additional features available for paid subscribers.
A pulsar–neutron star system, e.g, PSR B1913+16. A pulsar and a normal star; e.g, PSR J0045−7319, a system that is composed of a pulsar and main-sequence B star. Theoretically, a pulsar-black hole system is possible and would be of enormous scientific interest but no such system has yet been identified.
The Hulse–Taylor pulsar (known as PSR B1913+16, PSR J1915+1606 or PSR 1913+16) is a binary star system composed of a neutron star and a pulsar which orbit around their common center of mass. It is the first binary pulsar ever discovered.
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]
The flux density of astronomical sources is many orders of magnitude below 1 W·m −2 ·Hz −1, so the result is multiplied by 10 26 to get a more appropriate unit for natural astrophysical phenomena. [7] The millijansky, mJy, was sometimes referred to as a milli-flux unit (mfu) in older astronomical literature. [8]
The Black Widow Pulsar (PSR B1957+20) is an eclipsing binary millisecond pulsar in the Milky Way. Discovered in 1988, it is located roughly 6,500 light-years (2,000 parsecs) away from Earth . It orbits with a brown dwarf or Super-Jupiter companion with a period of 9.2 hours with an eclipse duration of approximately 20 minutes.
