Detectability Simulations of a NIR Surface Biosignature on Proxima Centauri b with Future Space Observatories

Connor O. Metz, Nancy Y. Kiang, Geronimo L. Villanueva +2

Telescope missions are currently being designed which will make direct imaging of habitable exoplanets possible in the near future, and studies are needed to quantify the detectabi…

The peak absorbance wavelength of photosynthetic pigments around other stars from spectral optimization

Owen R. Lehmer, David C. Catling, Mary N. Parenteau +2

In the search for life on other planets, the presence of photosynthetic vegetation may be detectable from the colors of light it reflects. On the modern Earth, this spectral reflec…

Climates of Warm Earth-Like Planets III: Fractional Habitability from a Water Cycle Perspective

Anthony D. Del Genio, M. J. Way, Nancy Y. Kiang +3

The habitable fraction of a planet's surface is important for the detectability of surface biosignatures. The extent and distribution of habitable areas is influenced by external p…

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…

Albedos, Equilibrium Temperatures, and Surface Temperatures of Habitable Planets

Anthony D. Del Genio, Nancy Y. Kiang, Michael J. Way +8

The potential habitability of known exoplanets is often categorized by a nominal equilibrium temperature assuming a Bond albedo of either 0.3, similar to Earth, or 0. As an indicat…

Climates of Warm Earth-like Planets I: 3-D Model Simulations

M. J. Way, A. D. Del Genio, I. Aleinov +3

We present a large ensemble of simulations of an Earth-like world with increasing insolation and rotation rate. Unlike previous work utilizing idealized aquaplanet configurations w…
