A simulation on the future trajectory of Kepler 78b

Mass : 1.69 +-0.41*M(earth) Radius:1.20 +-0.09*R(earth ) Star-Planet Seperation : ~0.01AU. A simulation on the future trajectory of Kepler 78b. Kepler 78b was discovered to be ~0.01 AU to its Star, way too close for planet formation here Transition state, orbit will decay

  1. Mass : 1.69+-0.41*M(earth) Radius:1.20+-0.09*R(earth) Star-Planet Seperation: ~0.01AU A simulation on the future trajectory of Kepler 78b • Kepler 78b was discovered to be ~0.01 AU to its Star, way too close for planet formation here • Transition state, orbit will decay • A simplified planet-Star system • All in real SI units • Runge-Kutta Method -Weihan Liu

  2. M(star)/kg 1.65087*(10^30) M(planet)/kg 1.009268*(10^25) Fg= -(G*(ms*mp)./(norm(rs-rp))^3).*(rs-rp) 149,597,870,7m 0.01AU Fdrag= (-(10^28)/norm(rs-rp)).*vp

  3. Wobble of the Star Orbit trajectory

  4. Run my simulation in: • main_code.m • kepler_ode.m
