Rising Stargirls: Benefits of a Creative Arts-Based Approach to Astronomy Education for Middle-School Girls from Underrepresented Groups
Maya Silverman, Aomawa L. Shields, Jessica N. Howard +2
Women from historically marginalized groups in the sciences continue to be severely underrepresented in the fields of physics and astronomy. Young girls identifying with these grou…
A One-Dimensional Energy Balance Model Parameterization for the Formation of CO2 Ice on the Surfaces of Eccentric Extrasolar Planets
Vidya Venkatesan, Aomawa L. Shields, Russell Deitrick +30
Eccentric planets may spend a significant portion of their orbits at large distances from their host stars, where low temperatures can cause atmospheric CO2 to condense out onto th…
Increased Surface Temperatures of Habitable White Dwarf Worlds Relative to Main-Sequence Exoplanets
Aomawa L. Shields, Eric T. Wolf, Eric Agol +1
Discoveries of giant planet candidates orbiting white dwarf stars and the demonstrated capabilities of the James Webb Space Telescope bring the possibility of detecting rocky plane…
Climate Regimes Across the Habitable Zone: a Comparison of Synchronous Rocky M- and K-dwarf Planets
Ana H Lobo, Aomawa L. Shields
M- and K-dwarf stars make up 86% of the stellar population and host many promising astronomical targets for detecting habitable climates in the near future. Of the two, M dwarfs cu…
Terminator Habitability: the Case for Limited Water Availability on M-dwarf Planets
Ana H. Lobo, Aomawa L. Shields, Igor Z. Palubski +1
Rocky planets orbiting M-dwarf stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets in the M-dwarf habitable zone are like…
The Sparse Atmospheric MOdel Sampling Analysis (SAMOSA) intercomparison: Motivations and protocol version 1.0. A CUISINES model intercomparison project
Jacob Haqq-Misra, Eric T. Wolf, Thomas J. Fauchez +2
Planets in synchronous rotation around low-mass stars are the most salient targets for current ground- and space-based missions to observe and characterize. Such model calculations…
The Effect of Land Albedo on the Climate of Land-Dominated Planets in the TRAPPIST-1 System
Andrew J. Rushby, Aomawa L. Shields, Eric T. Wolf +2
Variations in the reflective properties of the bulk material that comprises the surface of land-dominated planets will affect the planetary energy balance by interacting differentl…
Habitability and Water Loss Limits on Eccentric Planets Orbiting Main Sequence Stars
Igor Palubski, Aomawa Shields, Russell Deitrick
A planet's climate can be strongly affected by its orbital eccentricity and obliquity. Here we use a 1-dimensional energy balance model modified to include a simple runaway greenho…
The Effect of Land Fraction and Host Star Spectral Energy Distribution on the Planetary Albedo of Terrestrial Worlds
Andrew J. Rushby, Aomawa L. Shields, Manoj Joshi
The energy balance and climate of planets can be affected by the reflective properties of their land, ocean, and frozen surfaces. Here we investigate the effect of host star spectr…
Energy Budgets for Terrestrial Extrasolar Planets
Aomawa L. Shields, Cecilia M. Bitz, Igor Palubski
The pathways through which incoming energy is distributed between the surface and atmosphere has been analyzed for the Earth. However, the effect of the spectral energy distributio…
The Climates of Other Worlds: A Review of the Emerging Field of Exoplanet Climatology
Aomawa L. Shields
The discovery of planets orbiting stars other than the Sun has accelerated over the past decade, and this trend will continue as new space- and ground-based observatories employ ne…
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…
Hydrohalite Salt-albedo Feedback Could Cool M-dwarf Planets
Aomawa L. Shields, Regina C. Carns
A possible surface type that may form in the environments of M-dwarf planets is sodium chloride dihydrate, or "hydrohalite" (NaCl 2HO), which can precipitate in bare se…
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…
The Habitability of Planets Orbiting M-dwarf Stars
Aomawa L. Shields, Sarah Ballard, John Asher Johnson
The prospects for the habitability of M-dwarf planets have long been debated, due to key differences between the unique stellar and planetary environments around these low-mass sta…
The Effect of Orbital Configuration on the Possible Climates and Habitability of Kepler-62f
Aomawa L. Shields, Rory Barnes, Eric Agol +3
As lower-mass stars often host multiple rocky planets, gravitational interactions among planets can have significant effects on climate and habitability over long timescales. Here…
Spectrum-driven Planetary Deglaciation Due to Increases in Stellar Luminosity
Aomawa L. Shields, Cecilia M. Bitz, Victoria S. Meadows +2
Distant planets in globally ice-covered, "snowball", states may depend on increases in their host stars' luminosity to become hospitable for surface life. Using a General Circulati…
The Effect of Host Star Spectral Energy Distribution and Ice-Albedo Feedback on the Climate of Extrasolar Planets
Aomawa L. Shields, Victoria S. Meadows, Cecilia M. Bitz +3
Planetary climate can be affected by the interaction of the host star spectral energy distribution with the wavelength-dependent reflectivity of ice and snow. Here we explore this…
