The SUNRISE balloon-borne solar observatory consists of a 1 m aperture Gregory telescope, a UV filter imager, an imaging vector polarimeter, an image stabilization system, and further infrastructure. The first science flight of SUNRISE yielded high-quality data that revealed the structure, dynamics, and evolution of solar convection, oscillations

The joint consideration of theoretical and observational arguments is used to conclude that two different spot populations co-exist in the Sun.

Aims: We suggest an explanation for the high-frequency power excess surrounding active regions known as seismic halos. Methods: We use numerical simulations of magneto-acoustic wave propagation in a magnetostatic sunspot model. Results: We propose that seismic halos can be caused by the additional energy injected by high-frequency fast mode waves

Here we present two-dimensional hydrodynamic calculations of free expanding supergalactic winds, taking into consideration strong radiative cooling. Our main premise is that supergalactic winds are powered by collections of super-star clusters, each of which is a source of a high-metallicity supersonic diverging outflow. The interaction of winds
