Classification of magnetized star-planet interactions: dynamics and
... We explore a wide range of planetary and orbital parameters to cover the rich parameter space of Hot Jupiters. In particular, we consider two types of planets, one that is Jupiter-like in terms of its mass and radius, and another that is less massive but larger in size. We further investigate both t ...

Solar rays light the days, warm the soil, and provide plants with the raw energy they need to make food. We know the Earth’s energy comes from the Sun, but from where does the Sun’s energy ...
