HT Cas |
HT Cas is a binary system which emits X-rays. It has been observed with
the ASCA satellite, from which astrophysicists have determined the
following about HT Cas:
- It involves a smaller star that is a white dwarf and a larger star that
is nonetheless smaller than the Sun (the size of the larger star should
make sense, once you have made your calculations).
- This system has an inclination of 83 degrees. A 90 degrees
inclination system would be one where the smaller star traverses the
central star exactly in the middle, providing some evidence that it
exhibits a Total Eclipse) in its light curve.
- It's orbital velocity is 390 km/sec.
