Stellar Space Weather Effects On Potentially Habitable Planets
Stellar activity can reveal itself in the form of radiation (eg, enhanced X-ray coronal emission, flares) and particles (eg, winds, coronal mass ejections). Together, these phenomena shape the space weather […]

Land Fraction Diversity On Earth-like Planets And Implications For Their Habitability
A balanced ratio of ocean to land is believed to be essential for an Earth-like biosphere and one may conjecture that plate-tectonics planets should be similar in geological properties.
