X-ray and pulsars
SGXBs show typical the hard X-ray spectra of accreting pulsars and most show strong absorption as obscured HMXBs.
During the following decade, the magnetar hypothesis has become widely accepted as a likely explanation for soft gamma repeaters ( SGRs ) and anomalous X-ray pulsars ( AXPs ).
2008 ) see X-ray pulsars in outburst at > 1036 erg s − 1 and have counted 50 by the end of 2008.
X-ray bursters differ observationally from other X-ray transient sources ( such as X-ray pulsars and soft X-ray transients ), showing a sharp rise time ( 1 – 10 seconds ) followed by spectral softening ( a property of cooling black bodies ).
Aside from radio pulsars and X-ray pulsars, there are also gamma ray pulsars, which are mostly magnetars.
* Ultraviolet, X-ray and gamma ray astronomy study very energetic processes such as binary pulsars, black holes, magnetars, and many others.
In 1967, before the discovery of pulsars, Shklovsky examined the X-ray and optical observations of Scorpius X-1 and correctly concluded that the radiation comes from an accreting neutron star.
The RXTE observes X-rays from black holes, neutron stars, X-ray pulsars and X-ray bursts.
X-ray pulsars or accretion-powered pulsars are a class of astronomical objects that are X-ray sources displaying strict periodic variations in X-ray intensity.
Some companion stars of X-ray pulsars are very massive young stars, usually OB supergiants ( see stellar classification ), that emit a radiation driven stellar wind from their surface.
For still other types of X-ray pulsars, the companion star is a Be star that rotates very rapidly and apparently sheds a disk of gas around its equator.
The circumstellar disk around the Be star expands and contracts for unknown reasons, so these are transient X-ray pulsars that are observed only intermittently, often with months to years between episodes of observable X-ray pulsation.
