Awesome job! and Astronomically correct to boot! (The accepted distance to HT Cas is 140 parsecs.) You are continuing to demonstrate your aptitude in astronomy. Now you can finish your experiment using optical observations of the angular size of HT Cas, along with the distance you have found, to calculate the physical size of the central star, and get that job in Dr. Greenglow's lab this year!
