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.
