Coronal heating problem

The Sun’s outer atmosphere is much hotter than its visible surface. Which processes deliver and dissipate enough energy to maintain it?

Solar modelling problem

Measurements of the Sun’s composition and interior do not all agree with standard solar models. Which changes would make the different lines of evidence fit together?

Core-collapse supernova mechanism

The collapse of a massive star can launch an explosion. Which stars explode, and can models predict the explosion and remnant from the star’s pre-collapse structure?

Solar dynamo

Where and how does the Sun regenerate the magnetic field underlying its activity cycle?
