Pulsar P4 Time Computer with LED display ref. 3215-2 mens stainless steel watch circa 1975 Made in the USA A Pulsar LED watch from 1976. In 1970, Pulsar was a brand of the American Hamilton Watch Company which first announced that it was making and bringing the LED watch to market. It was developed jointly by American companies Hamilton and ...
The key property of a pulsar timing array is that the signal from a stochastic GW background will be correlated across the sightlines of pulsar pairs, while that from the other noise processes will not. [9] In the literature, this spatial correlation curve is called the Hellings-Downs curve or the overlap reduction function. [10]
A leather watch strap with a butterfly closure Four analog wristwatches for men with variants of the widespread metal watch strap made from stainless steel, the two in the middle being of the most common type. A watch strap, watch band, watch bracelet or watch belt is a bracelet that straps a wrist watch onto the wrist. [1]
The first digital watch was the Pulsar, introduced by the Hamilton Watch Company in 1972. The "Pulsar" became a brand name, and would later be acquired by Seiko in 1978. In 1982, a Pulsar watch (NL C01) was released which could store 24 digits, likely making it the first watch with user-programmable memory, or the first "memorybank" watch.
However Speidel returned to watchbands as soon as peace returned. In 1947 Speidel brought out its first modernized version of the scissor-type expansion band called the Golden Knight. [22] It proved to be a tremendous success in the men's watch bracelet field. The company also introduced elaborate packaging for its line of watch bracelets. [23 ...

The mass of the companion is ~1 solar mass (M ☉), while the pulsar mass is unusually large at 1.67 ± 0.02 M ☉; [3] the third largest precisely measured mass after those of PSR J1614−2230 and PSR J0348+0432. A companion, magnitude 18 in near-infrared light of 2.22 μm (the K S band), was recorded by the Gemini North observatory. [1]
March 2016) (Learn how and when to remove this message) In astronomy , a glitch is a sudden small increase of around 1 part in 1 million in the rotational frequency of a pulsar , which usually decreases steadily due to braking provided by the emission of radiation and high-energy particles.
