A pulsar (from pulsating radio source) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic...

magnetic axis is offset to the rotation axis, is known as the oblique rotator model. The origin of such high magnetic fields in Ap stars is problematic...

As a star's core collapses, its rotation rate increases due to conservation of angular momentum, so newly formed neutron stars typically rotate at up...

vary in brightness. As the star rotates we observe brightness variations of a few tenths of magnitudes. These stars rotate extremely rapidly (~100 km/s...

The primary star rotates rapidly, close to its breakup velocity, even faster than Achernar. Although some research on the companion star has been performed...

Rotating ellipsoidal variables are a class of close binary variable star systems whose components are ellipsoidal. They are not eclipsing, but fluctuations...

A rotating black hole is a black hole that possesses angular momentum. In particular, it rotates about one of its axes of symmetry. All celestial objects...

conditions: The star is in spectral class F8 to G8 It is on or near the main sequence It is single or part of a very wide binary It is not a rapid rotator It is...

identified the source as a pulsar, a rapidly rotating, highly magnetized neutron star. The neutron star rotates on its axis 17 times per second; thus the...

(4,500 mph), Regulus rotates every 16 hours at 1.1 million kph (700,000 mph). Astronomers have determined that if the star rotated 10% faster it would...

large tube that rotates to provide artificial gravity. A Ringworld (or Niven Ring) is an artificial ring encircling a star, rotating faster than orbital...

(6.1×1016 km; 3.8×1016 mi) away in the Cassiopeia constellation. The star rotates at a rate of 8.7 times a second. There is bow-shock pulsar wind nebula...

star rotates. Mizar, ζ Ursae Majoris, the second star in from the end of the handle of the Big Dipper, and the constellation's fourth-brightest star....

116.6±0.7 days. Later observations of the star's magnetic field subsequently revealed that the star rotates with a period of 89.8±4 days, consistent with...

discovered two pulsars orbiting each other, the first such system known. Rotating radio transients (RRATs) are a type of neutron stars discovered in 2006...

red star because he wanted to remove all evidence of the former Tsarist period. The star rotates in 360°. The height of the tower with the star is 71...

surface brightness that can lead to visible brightness variations as the star rotates. The spectra of red supergiants are similar to other cool stars, dominated...

Mathys found that the variation of the measured magnetic field as the star rotated was far from sinusoidal. They obtained an acceptable fit to the data...

phenomenon observed when an object moves across the face of a rotating star. The star is seen to undergo a redshift anomaly caused by the obscuration...

onto the neutron star as in the binary system Cen X-3. For still other types of X-ray pulsars, the companion star is a Be star that rotates very rapidly and...

star is determined by its radius and surface temperature. Many stars do not radiate uniformly across their entire surface. The rapidly rotating star Vega...

suggests that the star may be in a Maunder minimum period during which a star produces a reduced number of star spots. The star rotates at an inclination...
