Information on HT Cas
From the data obtained from the ASCA 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 white dwarf .012 x the
size of the Sun and a larger star that is .154 x the size of
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 resembles diagram b (Total Eclipse)
in the illustration of a variety of light
curves.
From optical observations, astronomers find that the orbital velocity is 390 km/sec.
