Gravity-Darkened Seasons on Planets
Spinning stars can potentially double the number of seasons that a planet experiences due to surface temperature variations on the stellar surface.
KELT-16b: a new benchmark for future exoplanet atmosphere studies
On KELT-16b you would melt. I would melt too. A look at an exciting and newly discovered Hot Jupiter, and why KELT-16b is a valuable addition to the group of boiling gas giant planets, and a fantastic target for future atmospheric studies.
Mars: Warm and cloudy with a chance of liquid water
Early in its history, cloudy weather could have helped Mars retain enough heat for liquid water to exist on its surface.
Driving planetary dynamos by giant impacts
Earlier than one billion years ago, Earth’s magnetic field had to be driven differently than today. But how? And what can we learn from this about magnetic fields on exoplanets?
Something from Nothing
What can we learn from the lack of giant planets found at wide separations?
Water worlds – self-arrests, thermostats and long-term climate stability
Water worlds – do they exist? Or is there an omnipotent self-regulation mechanism which makes terrestrial planets look like Earth?
