Figure 5: The radio pulsar equivalent of the Hertzsprung-Russell diagram - a physical diagram indicating the nature and evolution of neutron stars. Each dot represents a pulsar, stars represent pulsars associated with supernova remnants, circles indicate pulsars in binary systems and ellipses indicate pulsars in binary systems with eccentric orbits.

Next: Stars without Periods Up: Other Stars Previous: Stars with Highly . ... However, due to lower signal to noise their periods are less secure. ... This could be interpreted as a continuous distribution with statistically insignificant deviations which give the appearance of gaps or a real gap. ... When the distributions of periods greater five days are compared for the ONC stars and those near Orionis the KS test gives a 47% probability of these distributions being drawn from the same population. ...

... The evolution equation presented above indicates that an accreting compact star must endeavor to attain an equilibrium state in which the resultant torque vanishes (Davidson and Ostriker, 1973[ 38 ]; Lipunov and Shakura, 1976[ 109 ]). ... Let us turn to the case of disk accretion. ... Since , the equilibrium period in the case of disk accretion is close to the critical period, , separating accretion stage A and the propeller stage P . ...

Also, the Heliocentric correction cannot be applied to such lightcurves. ... This period search service is also available at the mirror sites: Mirror 1 , Mirror 2 , Mirror 3 , Mirror 4 . You may download the latest source code distribution and install the period search service at your own web server. ...

... Binary orbits in the acceleration/period plane . Circular Orbits . ... We first present the equations for the period and acceleration of a pulsar in an eccentric binary system as a function of its position in the orbit. ... In Freire, Kramer & Lyne (2001) (from where most of this text and following equations are taken), we describe in more detail how circular binary orbits can be determined from the observed periods and accelerations of the pulsar. ... where is the orbital period of the binary. ...

The orbital period of a satellite increases as its mean distance from Earth grows. The space shuttle in a low altitude circular orbit, just above the atmosphere, completes one circuit in about 90 minutes. ... If you have a suitable calculator, you can easily chek the value of T for R=6.6] A satellite orbiting above the equator at that distance keeps its position above the same spot on the ground; hence this is known as the synchronous orbit, from the Greek syn--same, chronos--time. ...

... If requested ( runbackground =Y), the task creates a background lightcurve, as well as a background spectrum for the imaging modes (FF, eFF, LW, SW) using background masks. ... The background masks are created by task badpixfind using threshold parameters, appropriate for the detection of real X-ray sources. ... As the GTIs strongly depend on the intended science this screening is not performed and only background masks, the lightcurve, and a GTI file are created by epchain . ...
