Modeling Repeated M-dwarf Flaring at an Earth-like Planet in the Habitable Zone: I. Atmospheric Effects for an Unmagnetized Planet
Matt A. Tilley, Antigona Segura, Victoria S. Meadows +2
Understanding the impact of active M-dwarf stars on the atmospheric equilibrium and surface conditions of a habitable zone Earth-like planet is key to assessing M dwarf planet habi…
Organic Haze as a Biosignature in Anoxic Earth-like Atmospheres
Giada N. Arney, Shawn D. Domagal-Goldman, Victoria S. Meadows
Early Earth may have hosted a biologically-mediated global organic haze during the Archean eon (3.8-2.5 billion years ago). This haze would have significantly impacted multiple asp…
Finding the Needles in the Haystacks: High-Fidelity Models of the Modern and Archean Solar System for Simulating Exoplanet Observations
Aki Roberge, Maxime J. Rizzo, Andrew P. Lincowski +10
We present two state-of-the-art models of the solar system, one corresponding to the present day and one to the Archean Eon 3.5 billion years ago. Each model contains spatial and s…
Detecting Proxima b's atmosphere with JWST targeting CO2 at 15 micron using a high-pass spectral filtering technique
I. Snellen, J. -M. Desert, L. Waters +15
Exoplanet Proxima b will be an important laboratory for the search for extraterrestrial life for the decades ahead. Here we discuss the prospects of detecting carbon dioxide at 15…
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…
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…
Pale Orange Dots: The Impact of Organic Haze on the Habitability and Detectability of Earthlike Exoplanets
Giada N. Arney, Victoria S. Meadows, Shawn D. Domagal-Goldman +5
Hazes are common in known planet atmospheres, and geochemical evidence suggests early Earth occasionally supported an organic haze with significant environmental and spectral conse…
