Low-mass X-ray binaries — Binaire X à faible masse Une binaire X à faible masse, ou LMXB (de l anglais Low Mass X ray Binary) est une étoile binaire rayonnant dans le domaine des rayons X (ce que l on appelle une binaire X), dont un des deux membres est une étoile à… … Wikipédia en Français
X-ray binary — Artist s impression of an X ray Binary X ray binaries are a class of binary stars that are luminous in X rays. The X rays are produced by matter falling from one component, called the donor (usually a relatively normal star) to the other… … Wikipedia
X-ray astronomy — X rays start at 0.008 nm and extend across the electromagnetic spectrum to 8 nm, over which the Earth s atmosphere is opaque. X ray astronomy is an observational branch of astronomy which deals with the study of X ray observation and detection… … Wikipedia
X-ray source — ▪ astronomy in astronomy, any of a class of cosmic objects that emit radiation at X ray wavelength. Because the Earth s atmosphere absorbs X rays (X ray) very efficiently, X ray telescopes and detectors must be carried high above it by… … Universalium
Ultraluminous X-ray source — An ultra luminous X ray source (ULX) is an astronomical source of X rays that is not in the nucleus of a galaxy, and is more luminous than 1039 erg/s (1032 watts), assuming that it radiates isotropically. Typically there is about one ULX per… … Wikipedia
Super Soft X-ray Source — (auf deutsch etwa superweiche Röntgenquelle) bezeichnet ein astronomisches Objekt, dessen elektromagnetische Strahlung überwiegend im Bereich der weichen Röntgenstrahlung (von 0,1 bis 2,5 keV) emittiert wird. Die meisten SSS sind in… … Deutsch Wikipedia
Intermediate-mass X-ray binary — An intermediate mass X ray binary (IMXB) is a binary star system where one of the components is a neutron star or a black hole. The other component is an intermediate mass star.ee also* X ray binary * Low mass X ray binary * High mass X ray… … Wikipedia
Soft X-ray transient — Soft X ray transients (often abbreviated to SXT) are also known as X ray novae . Typical SXTs are usually very faint, or even unobservable, in X rays and their apparent magnitude in the optical wavelengths is about 20. This is called the… … Wikipedia
Gamma ray burst progenitors — are the types of celestial objects that can emit gamma ray bursts (GRBs). GRBs show an extraordinary degree of diversity. They can last anywhere from a fraction of a second to many minutes. Bursts could have a single profile or oscillate wildly… … Wikipedia
Gamma ray burst — [ GRB 990123 taken on January 23, 1999. The burst is seen as a bright dot denoted by a square on the left, with an enlarged cutout on the right. The object above it with the finger like filaments is the originating galaxy. This galaxy seems to be … Wikipedia
