Information on X0748-676

From the data obtained from the ME experiment aboard the EXOSAT satellite, astrophysicists have also determined the following that you and your students may find interesting and useful.

  • It involves a smaller star that is a neutron star with an accretion disk and a larger star that is .2 x the size of the Sun (the size of the larger star should make sense, once you have made your calculations).

  • Since this system involves an accretion disk, one may not obtain the size of the neutron star. This is for two reasons. One reason is because the neutron star's accretion disk is never completely eclipsed. The other reason is because d1 would be the diameter of the accretion disk, not the star itself.

  • It's orbital velocity is 500 km/sec.
