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…
Warming early Mars with CO2 and H2
Ramses M. Ramirez, Ravi Kopparapu, Michael E. Zugger +3
The presence of valleys on ancient terrains of Mars suggest that liquid water flowed on the martian surface 3.8 billion years ago or before. The above-freezing temperatures require…
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…
