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