Geothermal heating enhances atmospheric asymmetries on synchronously rotating planets
Jacob Haqq-Misra, Ravi Kumar Kopparapu
Earth-like planets within the liquid water habitable zone of M type stars may evolve into synchronous rotators. On these planets, the sub-stellar hemisphere experiences perpetual d…
On the Frequency of Potential Venus Analogs from Kepler Data
Stephen R. Kane, Ravi Kumar Kopparapu, Shawn D. Domagal-Goldman
The field of exoplanetary science has seen a dramatic improvement in sensitivity to terrestrial planets over recent years. Such discoveries have been a key feature of results from…
The Ĝ Infrared Search for Extraterrestrial Civilizations with Large Energy Supplies. II. Framework, Strategy, and First Result
J. T. Wright, R. Griffith, S. Sigurðsson +2
We describe the framework and strategy of the Ĝ infrared search for extraterrestrial civilizations with large energy supplies, which will use the wide-field infrared surveys of WIS…
The Ĝ Infrared Search for Extraterrestrial Civilizations with Large Energy Supplies. I. Background and Justification
J. T. Wright, B. Mullan, S. Sigurðsson +1
We motivate the Ĝ infrared search for extraterrestrial civilizations with large energy supplies. We discuss some philosophical difficulties of SETI, and how communication SETI circ…
Damping of glacial-interglacial cycles from anthropogenic forcing
Jacob Haqq-Misra
Climate variability over the past million years shows a strong glacial-interglacial cycle of ~100,000 years as a combined result of Milankovitch orbital forcing and climatic resona…
Habitable Zones Around Main-Sequence Stars: Dependence on Planetary Mass
Ravi kumar Kopparapu, Ramses M. Ramirez, James SchottelKotte +3
The ongoing discoveries of extrasolar planets are unveiling a wide range of terrestrial mass (size) planets around their host stars. In this letter, we present estimates of habitab…
