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…
The year-long flux variations in Boyajian's star are asymmetric or aperiodic
Michael Hippke, Daniel Angerhausen
We combine and calibrate publicly available data for Boyajian's star including photometry from ASAS (SN, V, I), Kepler, Gaia, SuperWASP, and citizen scientist observations (AAVSO,…
Demarcating circulation regimes of synchronously rotating terrestrial planets within the habitable zone
Jacob Haqq-Misra, Eric. T. Wolf, Manoj Joshi +2
We investigate the atmospheric dynamics of terrestrial planets in synchronous rotation within the habitable zone of low-mass stars using the Community Atmosphere Model (CAM). The s…
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…
Exoplanet Biosignatures: Understanding Oxygen as a Biosignature in the Context of Its Environment
Victoria S. Meadows, Christopher T. Reinhard, Giada N. Arney +13
Here we review how environmental context can be used to interpret whether O2 is a biosignature in extrasolar planetary observations. This paper builds on the overview of current bi…
Habitable Moist Atmospheres On Terrestrial Planets Near the Inner Edge Of the Habitable Zone Around M-dwarfs
Ravi kumar Kopparapu, Eric T. Wolf, Giada Arney +4
Terrestrial planets in the habitable zones (HZs) of low-mass stars and cool dwarfs have received significant scrutiny recently because their shorter orbital periods increase their…
Exoplanet Biosignatures: Future Directions
Sara I. Walker, William Bains, Leroy Cronin +11
Exoplanet science promises a continued rapid accumulation of new observations in the near future, energizing a drive to understand and interpret the forthcoming wealth of data to i…
Exoplanet Biosignatures: Observational Prospects
Yuka Fujii, Daniel Angerhausen, Russell Deitrick +9
Exoplanet hunting efforts have revealed the prevalence of exotic worlds with diverse properties, including Earth-sized bodies, which has fueled our endeavor to search for life beyo…
Exoplanet Biosignatures: A Review of Remotely Detectable Signs of Life
Edward W. Schwieterman, Nancy Y. Kiang, Mary N. Parenteau +15
In the coming years and decades, advanced space- and ground-based observatories will allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially habitab…
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…
False negatives for remote life detection on ocean-bearing planets: Lessons from the early Earth
C. T. Reinhard, S. L. Olson, E. W. Schwieterman +1
Ocean-atmosphere chemistry on Earth has undergone dramatic evolutionary changes through its long history, with potentially significant ramifications for the emergence and long-term…
