A Simplified Photodynamical Model for Planetary Mass Determination in Low-Eccentricity Multi-Transiting Systems
Gideon Yoffe, Aviv Ofir, Oded Aharonson
Inferring planetary parameters from transit timing variations is challenging for small exoplanets because their transits may be so weak that determination of individual transit tim…
Light-Curve Evolution due to Secular Dynamics and the Vanishing Transits of KOI 120.01
Yair Judkovsky, Aviv Ofir, Oded Aharonson
Non-Keplerian dynamics of planetary orbits manifest in the transit light-curve as variations of different types. In addition to Transit Timing Variations (TTV's), the shape of the…
Micro Cold Traps on the Moon
Paul O. Hayne, Oded Aharonson, Norbert Schörghofer
Water ice is thought to be trapped in large permanently shadowed regions (PSRs) in the Moon's polar regions, due to their extremely low temperatures. Here, we show that many unmapp…
