Exoplanet detection using transit method simulation. The Exoplanet Detection: Transit Method model simulates the detection of exoplanets by using the transit method. In this method, the light curve from a star, and how it changes over time due to exoplanet transits, is observed and then analyzed. In this simulation the exoplanet orbits the star (sun-sized) in circular motion via Kepler's third law. When the exoplanet passes in front of the star (transits), it blocks part of the starlight. This decrease in starlight is shown on the graph.

If the exoplanet is close enough to the central star, and has sufficient reflectivity, or albedo, it can reflect enough of the starlight to be seen on the light curve. In the simulation the star-exoplanet system is shown as seen from Earth (edge on view) but magnified greatly, and with the star and planet sizes not shown to the scale of the orbit. The radius of the central star (relative to the radius of Sun),semi-major axis of the exoplanet (in AU), radius of the exoplanet (relative to the radius of Jupiter), the exoplanet's albedo (reflectivity), and the inclination of the system relative to Earth can be changed.

Controls
1. Time Step: sets the time step so that the simulation can be sped up or slowed down to allow for faster times.
2. R/R_J Slider: changes the radius of the exoplanet (relative to the radius of Jupiter).
3. R_star/R_Sun Slider: changes the radius of the central (relative to the radius of Sun).
4. Semi-major axis Slider: changes the semi-major axis of the exoplanet (AU).
5. Albedo Slider: changes the reflectivity of the exoplant (0-1).
6. Inclination Slider (right-hand side of the View): changes the inclination of the system relative to Earth (default value is edge on).
