HANDA, Toshihiro(IoA, The University of Tokyo)
Purpose
We have performed “UNIVERSE Liveshow”
Gravitational lens effect Simulator Intersteller flythrough ( HippLiner )
Motivation
Needs to think further questions
• How are rays bended near the blackhole?
(Gravitational lens effect Simulator)
• Are there extra solar planets in destination?
(HippLiner)
Develop the new add-on programs.
Raytrace Simulator
Purpose
• Add-on for “Gravitational lens simulator”
• Visualize ray trails near blackhole
Method
• Solve the geodesic equation for photon in
the Schwardzshild metric
Exoplanet Simulator
–Wakusei guruguruPurpose
• Add-on for Interstellar spaceship simulator “HippLiner”.
• Show the exoplanet system
selected from “HippLiner”.
Feature
• 155 171 exoplanet systems avaliable. (Current)
• Semi-automatic update of exoplanet systems catalog from
online database
The extra solar planets encyropedia

Conclusion
We devloped a raytrace simulator based on
General Relativity for “UNIVERSE
Liveshow” . It is very instructive to show
ray trails near a blackhole.
We developed an extra solar system
simulator. It is very effective to imagine a
travel to exoplanets with Interstellar
spaceship simulator “HippLiner” .
