Notes from Independent Study Meeting
                      Feb 03, 2022

Present: Richmond, Dayal

  - Dayal shows spreadsheet with sample calculations of the photon
          force on the sail for various combinations of area and
          surface density

          - all current combinations yield a photon force which is
                 smaller than the gravitational force due to the Sun;
                 that's fine for now.


  - We discuss the issue of modifying the code to add the photon force 
          on a sail (but NOT adding photon force to other objects)

          - Dayal plans to compute the acceleration of the sail in each
                direction due to photon pressure, then add this 
                to the existing value of acceleration of the sail
                due to gravitational force


  - goals for next meeting (Mon, Feb 7): 
   
          - show results of the code with photon pressure added
