EXONEST: The Bayesian Exoplanetary Explorer
Kevin H. Knuth, Ben Placek, Daniel Angerhausen +4
The fields of astronomy and astrophysics are currently engaged in an unprecedented era of discovery as recent missions have revealed thousands of exoplanets orbiting other stars. W…
Analyzing Exoplanet Phase Curve Information Content: Toward Optimized Observing Strategies
Ben Placek, Daniel Angerhausen, Kevin H. Knuth
Secondary eclipses and phase curves reveal information about the reflectivity and heat distribution in exoplanet atmospheres. The phase curve is composed of a combination of reflec…
Simultaneous multicolour optical and near-IR transit photometry of GJ 1214b with SOFIA
D. Angerhausen, C. Dreyer, B. Placek +24
The benchmark exoplanet GJ 1214b is one of the best studied transiting planets in the transition zone between rocky Earth-sized planets and gas or ice giants. This class of super-E…
Predictable patterns in planetary transit timing variations and transit duration variations due to exomoons
René Heller, Michael Hippke, Ben Placek +2
We present new ways to identify single and multiple moons around extrasolar planets using planetary transit timing variations (TTVs) and transit duration variations (TDVs). For pla…
Combining Photometry From Kepler and TESS to Improve Short-Period Exoplanet Characterization
Ben Placek, Kevin H. Knuth, Daniel Angerhausen
Planets emit thermal radiation and reflect incident light that they recieve from their host stars. As a planet orbits it's host star the photometric variations associated with thes…
Characterization of Kepler-91b and the Investigation of a Potential Trojan Companion Using EXONEST
Ben Placek, Kevin H. Knuth, Daniel Angerhausen +1
Presented here is an independent re-analysis of the Kepler light curve of Kepler-91 (KIC 8219268). Using the EXONEST software package, which provides both Bayesian parameter estima…
Bayesian Evidence and Model Selection
Kevin H. Knuth, Michael Habeck, Nabin K. Malakar +2
In this paper we review the concepts of Bayesian evidence and Bayes factors, also known as log odds ratios, and their application to model selection. The theory is presented along…
A Bayesian Analysis of HAT-P-7b Using the EXONEST Algorithm
Ben Placek, Kevin H. Knuth
The study of exoplanets (planets orbiting other stars) is revolutionizing the way we view our universe. High-precision photometric data provided by the Kepler Space Telescope (Kepl…
EXONEST: Bayesian Model Selection Applied to the Detection and Characterization of Exoplanets Via Photometric Variations
Ben Placek, Kevin H. Knuth, Daniel Angerhausen
EXONEST is an algorithm dedicated to detecting and characterizing the photometric signatures of exoplanets, which include reflection and thermal emission, Doppler boosting, and ell…
