Mean a254

This page presents lightcurves for Mean a254 produced using the KEPLER simulation code, and analysed following Lampe, Heger & Galloway (2015).

The curve presented here is as measured in the neutron star's Newtonian rest frame. To compare this to an observation it is necessary to apply redshift corrections. Instructions for doing this are provided in the companion paper and a summary is provided here

This averaged lightcurve comes from a train of 30 bursts that can be viewed here


Lightcurve

The mean luminosity (green line, left-hand y-axis), is plotted with the lighter green band giving the 1-sigma error calculated from the variation in the lightcurves included in the average. The radius is shown in blue (right-hand y-axis)


Parameters

The following table presents the initial conditions for the model and if a burst occurred, the average burst parameters.
