We study the magnetic and tidal interactions of a gas-giant exoplanet with its host star and with its exomoons, and focus on their retention. We briefly revisit the scaling law […]

Do Earth-like Exoplanets Have Magnetic Fields? Far-off Radio Signal Is Promising Sign
Earth’s magnetic field does more than keep everyone’s compass needles pointed in the same direction. It also helps preserve Earth’s sliver of life-sustaining atmosphere by deflecting high energy particles and […]

The Crucial Role Of Surface Magnetic Fields For Stellar Dynamos: Epsilon Eridani, 61 Cygni A, and the Sun
Cool main-sequence stars, such as the Sun, have magnetic fields which are generated by an internal dynamo mechanism. In the Sun, the dynamo mechanism produces a balance between the amounts […]
