Identification and Mitigation of a Vibrational Telescope Systematic with Application to Spitzer
Ryan C. Challener, Joseph Harrington, James Jenkins +17
We observed Proxima Centauri with the Spitzer Space Telescope InfraRed Array Camera (IRAC) five times in 2016 and 2017 to search for transits of Proxima Centauri b. Following stand…
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…
