Tidal Dissipation in Dual-Body, Highly Eccentric, and Non-synchronously Rotating Systems: Applications to Pluto-Charon and the Exoplanet TRAPPIST-1e
Joe P. Renaud, Wade G. Henning, Prabal Saxena +4
Using the Andrade-derived Sundberg-Cooper rheology, we apply several improvements to the secular tidal evolution of TRAPPIST-1e and the early history of Pluto-Charon under the simp…
Charon: A brief history of tides
Alyssa Rose Rhoden, Helle L. Skjetne, Wade G. Henning +9
In 2015, the New Horizons spacecraft flew past Pluto and its moon Charon, providing the first clear look at the surface of Charon. New Horizons images revealed an ancient surface,…
Impact of Space Weather on Climate and Habitability of Terrestrial Type Exoplanets
V. S. Airapetian, R. Barnes, O. Cohen +43
The current progress in the detection of terrestrial type exoplanets has opened a new avenue in the characterization of exoplanetary atmospheres and in the search for biosignatures…
Impacts of Quantum Chemistry Calculations on Exoplanetary Science, Planetary Astronomy, and Astrophysics
Der-you Kao, Marko Gacesa, Renata M. Wentzcovitch +26
Several of NASA missions (TESS, JWST, WFIRST, etc.) and mission concepts (LUVOIR, HabEx, and OST) emphasize the exploration and characterization of exoplanets, and the study of the…
Reconstructing Extreme Space Weather from Planet Hosting Stars
V. S. Airapetian, V. Adibekyan, M. Ansdell +80
The field of exoplanetary science is making rapid progress both in statistical studies of exoplanet properties as well as in individual characterization. As space missions provide…
The Importance of 3D General Circulation Models for Characterizing the Climate and Habitability of Terrestrial Extrasolar Planets
Eric T. Wolf, Ravi Kopparapu, Vladimir Airapetian +27
While recently discovered exotic new planet-types have both challenged our imaginations and broadened our knowledge of planetary system workings, perhaps the most compelling object…
Seismicity on Tidally Active Solid-Surface Worlds
T. A. Hurford, W. G. Henning, R. Maguire +8
Tidal interactions between planets or stars and the bodies that orbit them dissipate energy in their interiors. The energy dissipated drives internal heating and a fraction of that…
Highly Volcanic Exoplanets, Lava Worlds, and Magma Ocean Worlds: An Emerging Class of Dynamic Exoplanets of Significant Scientific Priority
Wade G. Henning, Joseph P. Renaud, Prabal Saxena +39
Highly volcanic exoplanets, which can be variously characterized as 'lava worlds', 'magma ocean worlds', or 'super-Ios' are high priority targets for investigation. The term 'lava…
Exoplanet Science Priorities from the Perspective of Internal and Surface Processes for Silicate and Ice Dominated Worlds
Wade G. Henning, Joseph P. Renaud, Avi M. Mandell +35
The geophysics of extrasolar planets is a scientific topic often regarded as standing largely beyond the reach of near-term observations. This reality in no way diminishes the cent…
Exoplanet Diversity in the Era of Space-based Direct Imaging Missions
Ravi Kopparapu, Eric Hebrard, Rus Belikov +55
This whitepaper discusses the diversity of exoplanets that could be detected by future observations, so that comparative exoplanetology can be performed in the upcoming era of larg…
Exploring Extreme Space Weather Factors of Exoplanetary Habitability
V. S. Airapetian, V. Adibekyan, M. Ansdell +46
It is currently unknown how common life is on exoplanets, or how long planets can remain viable for life. To date, we have a superficial notion of habitability, a necessary first s…
Life Beyond the Solar System: Observation and Modeling of Exoplanet Environments
Anthony Del Genio, Vladimir Airapetian, Daniel Apai +8
The search for life on planets outside our solar system has largely been the province of the astrophysics community until recently. A major development since the NASA Astrobiology…
Life Beyond the Solar System: Space Weather and Its Impact on Habitable Worlds
V. S. Airapetian, W. C. Danchi, C. F. Dong +33
The search of life in the Universe is a fundamental problem of astrobiology and a major priority for NASA. A key area of major progress since the NASA Astrobiology Strategy 2015 (N…
Increased Tidal Dissipation Using Advanced Rheological Models: Implications for Io and Tidally Active Exoplanets
Joe P. Renaud, Wade G. Henning
The advanced rheological models of Andrade (1910) and Sundberg & Cooper (2010) are compared to the traditional Maxwell model to understand how each affects the tidal dissipation of…
Relevance of Tidal Heating on Large TNOs
Prabal Saxena, Joe Renaud, Wade G. Henning +2
We examine the relevance of tidal heating for large Trans-Neptunian Objects, with a focus on its potential to melt and maintain layers of subsurface liquid water. Depending on thei…
A Self-Consistent Model of the Circumstellar Debris Created by a Giant Hypervelocity Impact in the HD172555 System
B. C. Johnson, C. M. Lisse, C. H. Chen +8
Spectral modeling of the large infrared excess in the Spitzer IRS spectra of HD 172555 suggests that there is more than 10^19 kg of sub-micron dust in the system. Using physical ar…
Detecting Volcanism on Extrasolar Planets
L. Kaltenegger, W. G. Henning, D. D. Sasselov
The search for extrasolar rocky planets has already found the first transiting rocky super-Earth, Corot 7b, with a surface temperature that allows for magma oceans. Here we ask if…
Tidally Heated Terrestrial Exoplanets: Viscoelastic Response Models
Wade G. Henning, Richard J. O'Connell, Dimitar D. Sasselov
Tidal friction in exoplanet systems, driven by orbits that allow for durable nonzero eccentricities at short heliocentric periods, can generate internal heating far in excess of th…
