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…
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…
The Drake Equation as a Function of Spectral Type and Time
Jacob Haqq-Misra, Ravi Kumar Kopparapu
This chapter draws upon astronomical observations and modeling to constrain the prevalence of communicative civilizations in the galaxy. We discuss the dependence of the Drake equa…
Why do we find ourselves around a yellow star instead of a red star?
Jacob Haqq-Misra, Ravi Kumar Kopparpu, Eric T. Wolf
M-dwarf stars are more abundant than G-dwarf stars, so our position as observers on a planet orbiting a G-dwarf raises questions about the suitability of other stellar types for su…
Constraints on Climate and Habitability for Earth-like Exoplanets Determined from a General Circulation Model
Eric T. Wolf, Aomawa L. Shields, Ravi K. Kopparapu +2
Conventional definitions of habitability require abundant liquid surface water to exist continuously over geologic timescales. Water in each of its thermodynamic phases interacts w…
