Stellarium VI, March 30: Parallax Stars© Joseph West 2015, modified by Brendon MikulaWe now leave the comfy confines of our solar system, and look at stars in our galaxy.I. Set Default Location1. Remember to start Stellarium with the “fallback mode” option if you need to.2. Check to make sure that Terre Haute is still your default location. If not, reset it.3. Change your surroundings in another menu, if you like.II. Set Viewing OptionsSet the time to 11:59 pm, November 1 (Sunday). All of the stars under consideration are visible in the night sky at this time.III. Get the Data1. Find your star.2. Record the color the star appears to be on Stellarium.3. Sometime during the week, go outside and find your star. Where are you, and what is on the ground in front of you (name of building on campus, Mogger’s restaurant, northeast corner of my back yard, or other landmark). Note that some of the stars (Rigeland Betelgeuse in particular) will be below the horizon until after 10 PM or so. If you have an early bedtime, choose Polaris or Aldebaran.4. The next day (in daylight) face the same way, at the same location and TAKE A PICTURE, and attach it to your paper.5. Find c Ori (HIP 26237) on Stellarium, and zoom in on it a little bit.NOTE:A start with a spectral type listed with a subheading of “var” indicates a star that is “variable.” A spectral type with a subheading of “e” is extremely low mass (less than 0.2 Msun, or less than 130 Mjupiter), and extremely low output (less than 0.2% that of the sun). So, you might see a star listed as M5(Ve), which would be an M5 star that is variable and is very small and dim, on the scale of stars.1VI.
