Astro capstone meeting notes:  Jan 26, 2022

Present: Richmond, Dussault, Lertviwatkul

  Nititee shows his light curves

     - converted intensities to magnitudes
              graphs should be made with bright at top of vertical axis,
                    faint at bottom of vertical axis

     - calibrated using one comparison star
              please create a second light curve calibrated against
                    a second comparison star
  
     - compare light curve to published versions 
              are they very similar?  In one case, yes!



  Michael shows his light curves

     - still working on measuring B-band images

     - keep working

     - make curves (as described above) and compare to those in the
              literature (as described above)

     - try to identify _reasons_ for regions with many bad measurements


  Richmond discusses how radial velocity curves can be used to
              compute the masses of stars in a system

     - see information at this page:
        http://spiff.rit.edu/classes/phys370/lectures/eclipse_1/eclipse_1.html

     - necessary to find radial velocity measurements in the literature
              measure (or look up) the maximum speed of each star away
                  from their average velocity

     - use period and velocity to compute the size of each star's orbit


   For next time,

     - calculate the DEPTH of the primary and secondary minimum dips
              in both B and V 
              compare these depths to values in the literature

     - divide the light curve into bins of 0.01 in phase
              compute average of V-band mags in each bin
              compute average of B-band mags in each bin
              compute an average (B-V) color in each bin
              make a "color curve": (B-V) on vertical axis, phase on horiz axis

     - we can use the "color curve" to deduce temperatures of the stars
