Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Maximum Lifetime of the Vegetative Biosphere
Jacob Haqq-Misra, Eric Wolf
We use a three-dimensional model to calculate steady-state climates at various intervals in Earth's future, across a parameter space of increasing insolation and decreasing CO…
Exploring TRAPPIST-1 Climate States with an Energy Balance Model
Jacob Haqq-Misra
This paper presents a version of the HEXTOR energy balance model that has been configured for the study of habitable terrestrial planets orbiting low-mass stars. The model is valid…
Alternate states and intermingledness in complex high-dimensional systems
George Datseris, Johannes Lohmann, Oisín Hamilton +1
Many natural systems posses, and can transition between, multiple alternative states. For example, a climate ``tipping element'' is a climate component that can transition to an al…
Functionality of Ice Line Latitudinal EBM Tenacity (FILLET). Protocol Version 1.1
Rory Barnes, Russell Deitrick, Jacob Haqq-Misra +5
The Functionality of Ice Line Latitudinal EBM Tenacity (FILLET) project is a CUISINES exoplanet model intercomparison project (exo-MIP) that compares various energy balance models…
Chemistry, Climate, and Transmission Spectra of TRAPPIST-1 e Explored with a Multimodel Sparse Sampled Ensemble
Eric T. Wolf, Edward W. Schwieterman, Jacob Haqq-Misra +6
TRAPPIST-1 e is one of a few habitable zone exoplanets that is amenable to characterization in the near term. In this study our motivations are both scientific and technical. Our t…
Wind Power as a Technosignature on M-dwarf Planets
Jacob Haqq-Misra, Mykhaylo Danylov
We suggest that the large-scale deployment of wind turbines on an M-dwarf planet could produce observable technosignatures. Motivated by observations of hypersonic wind velocities…
K2-18b Does Not Meet The Standards of Evidence For Life
Kevin B. Stevenson, Jacob Lustig-Yaeger, E. M. May +7
K2-18b, a temperate sub-Neptune, has garnered significant attention due to claims of possible biosignatures in its atmosphere. Low-confidence detections of dimethyl sulfide (DMS) a…
The challenge of detecting remote spectroscopic signatures from radionuclides
Jacob Haqq-Misra, Vincent Kofman, Ravi K. Kopparapu
The characterization of exoplanetary atmospheres through transit spectra is becoming increasingly feasible, and technology for direct detection remains ongoing. The possibility of…
The CUISINES Framework for Conducting Exoplanet Model Intercomparison Projects, Version 1.0
Linda E. Sohl, Thomas J. Fauchez, Shawn Domagal-Goldman +10
As JWST begins to return observations, it is more important than ever that exoplanet climate models can consistently and correctly predict the observability of exoplanets, retrieva…
A Model for Economic Freedom on Mars
Jacob Haqq-Misra
The momentum of human spaceflight initiatives continues to build toward Mars, and technological advances may eventually enable the potential for permanent space settlement. Aspirat…
Interpolation and synthesis of sparse samples in exoplanet atmospheric modeling
Jacob Haqq-Misra, Eric T. Wolf, Thomas J. Fauchez +1
This paper highlights methods from geostatistics that are relevant to the interpretation, intercomparison, and synthesis of atmospheric model data, with a specific application to e…
Detectability of Solar Panels as a Technosignature
Ravi Kopparapu, Vincent Kofman, Jacob Haqq-Misra +2
In this work, we assess the potential detectability of solar panels made of silicon on an Earth-like exoplanet as a potential technosignature. Silicon-based photovoltaic cells have…
Artificial Greenhouse Gases as Exoplanet Technosignatures
Edward W. Schwieterman, Thomas J. Fauchez, Jacob Haqq-Misra +6
Atmospheric pollutants such as CFCs and NO have been proposed as potential remotely detectable atmospheric technosignature gases. Here we investigate the potential for artifi…
A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST
TRAPPIST-1 JWST Community Initiative, :, Julien de Wit +80
Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominen…
