determination of a neutron star radius. One method is to study X-ray bursters - these are neutron stars that are still accreting material from a companion in a...

X-radiation (composed of X-rays) is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding...

Thompson, Duncan (1995) - SGRs as magnetized neutron stars Romani & Yadigaroglu 1995 - gamma-ray pulsars - emission zones and viewing geometries Gil,...

actually absorb X-rays and release energy as photons. X-Ray Diffraction measures how light wave reflect off the spacing between atoms, while X-Ray Fluorescence...

Combinations of w:X-ray images from the Chandra observatory with Hubble's "Pillars" image have shown that X-ray sources (from young stars) do not coincide...

rotation-powered radio pulsar and an accretion powered X-ray source. Are all pulsars neutron stars? The answer depends on your definition of a pulsar. Hallinan...

perspectives. Observations made by w:Chandra X-ray Observatory indicate the presence of loops and rings in the hot X-ray emitting gas that permeate the cluster...

for months, and remained visible at night for several years. At X-ray and gamma-ray energies above 30 KeV, the Crab is generally the strongest persistent...

radio imaging of the cluster and identified an X-ray source X9 as a new black hole candidate. 300 X-ray sources were detected in the globular cluster by...

binary neutron stars or a neutron star with a black hole. The observation of minutes to hours of X-ray flashes after a short gamma-ray burst is consistent...

that occur about once every ten years. The w:Chandra X-ray Observatory detected fluctuating w:X-ray emissions from a location approximately 600 light-years...

high number of 89 w:variable stars, many of them of the w:RR Lyrae type. The globular also contains a number of w:x-ray sources, thought to be close w:binary...

Contents Instructions and tips for earning the Stars honor can be found in the Nature chapter. The stars appear to move in two different ways. The first...

holes or w:neutron stars, which are heating incoming gas to millions of kelvins and emitting X-rays. The spectrum of the neutron stars is the same as the...

zones at high latitudes on the planets. X-rays are higher energy and shorter wavelength than UV. Astronomy in X-rays has specific challenges that do not affect...

of a particle of visible light. An X-ray photon will knock the electron right out of an atom, as a result an X-ray can't be generated by electrons transitioning...
