Astronomical Orbiting Observatory

The purpose of this code is to compute the value of Chandrasekhar's H function (sometimes called Ambartsumian's or Busbridge's H function) used in many diffuse reflectance and atmospheric/stellar light scattering and emission calculations. The method for performing the calculation are used here...

The Ejs N-body Orbits model displays the dynamics of three to five identical masses orbiting each other subject to Newtonian gravity. The simulation displays the periodic orbital motion of the masses. The initial configuration of the system can be changed via slider. You can modify this...

The Ejs Keplerian Orbit model displays the dynamics of a mass orbiting a much larger mass subject to Newtonian gravity. The simulation displays the motion of the smaller mass and the effective potential energy diagram. The initial energy of the system can be changed via textbox and the initial...

The Stellar Aberration 3D Model illustrates the phenomenon known as the aberration of starlight, first reported by James Bradley in 1729. Aberration occurs because light has a finite speed, and thus light from a star takes a finite amount of time to travel through the tube of a telescope. During...

The EJS Differential Galactic Rotation Model illustrates the model of galactic rotation proposed by Jan Oort in 1927. In Oort's model most of the mass of the galaxy is concentrated at the center. Stars move in circular orbits around the center, with orbital speeds that are inversely proportional...
