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.
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?
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?
Probing the Galaxy with Dead Stars
White dwarf stars are the final evolutionary state of most stars. They are everywhere in the Galaxy and are relatively easy to model. So can we learn about our Galaxy solely by studying them? The authors of today’s paper show us a way.
