The neutron star is regularly eclipsed by its giant companion every 2.1 days; [6] these regular X-ray eclipses last approximately 1/4 the orbital period. There are also sporadic X-ray off durations. The spin period history of Centaurus X-3 shows a spin-up trend that is very prominent in the long-term decrease in its pulse period. This spin-up ...

The online video game platform and game creation system Roblox has numerous games (officially referred to as "experiences") [1] [2] created by users of its creation tool, Roblox Studio. Due to Roblox ' s popularity, various games created on the site have grown in popularity, with some games having millions of monthly active players and 5,000 ...
X-ray star may refer to: Be/X-ray binary, a class of high-mass X-ray binaries that consist of a Be star and a neutron star; X-ray binary, a class of binary stars that are luminous in X-rays; X-ray burster, a class of X-ray binary stars exhibiting periodic and rapid increases in luminosity that peak in the X-ray regime of the electromagnetic ...
An X-ray pulsar is a type of binary star system consisting of a typical star (stellar companion) in orbit around a magnetized neutron star.The magnetic field strength at the surface of the neutron star is typically about 10 8 Tesla, over a trillion times stronger than the strength of the magnetic field measured at the surface of the Earth (60 μT).
Scorpius X-1 was the first extrasolar X-ray source discovered, and, aside from the Sun, it is the strongest apparent non-transient source of X-rays in the sky. [3] The X-ray flux varies day-to-day, and is associated with an optically visible star , V818 Scorpii , that has an apparent magnitude which fluctuates between 12-13.
HD 106906 is a binary star [6] system in the southern constellation of Crux. It is too faint to be visible to the naked eye, having a combined apparent visual magnitude of 7.80. [ 2 ] The distance to this system is approximately 337 light years based on parallax , and it is receding from the Sun with a radial velocity of +10 km/s. [ 2 ]
BL 1-5, 7-1, 9-1, 9-2, 11-1, 11-3, 12-2 These beamlines are used for macromolecular x-ray crystallography. All of the beamlines are for general use, except for beamline 12-2, which was funded in part by Caltech via a gift from the Gordon and Betty Moore Foundation. As a result, 40% of beamtime on 12-2 is reserved for Caltech researchers.
