Numerical Validation of the Yarkovsky Effect in Super-Fast Rotating Asteroids
Dusan Marceta, Bojan Novakovic, Marko Gavrilovic
Recent discoveries show that asteroids spinning in less than a few minutes undergo sizeable semi-major-axis drifts, possibly driven by the Yarkovsky effect. Analytical formulas can…
