We present a convolutional neural network, which we train to identify planetary transit signals and dismiss false positives.

Orbital Stability of Circumstellar Planets in Binary Systems

1 code implementation • 23 Dec 2019 • Billy Quarles, Gongjie Li, Veselin Kostov, Nader Haghighipour

Planets that orbit only one of the stars in stellar binary systems (i. e., circumstellar) are dynamically constrained to a limited range of orbital parameters and thus understanding conditions on their stability is of great importance in exoplanet searches.

Stability Limits of Circumbinary Planets: Is There a Pile-up in the Kepler CBPs?

1 code implementation • 24 Feb 2018 • Billy Quarles, Suman Satyal, Veselin Kostov, Nathan Kaib, Nader Haghighipour

The stability limit for circumbinary planets (CBPs) is not well defined and can depend on initial parameters defining either the planetary orbit or the inner binary orbit.
