Even though the Sun is the nearest star to us, there’s a lot we still don’t understand about it and its activity. These authors present an interesting case of a unique type of solar radio emission occurring under conditions it doesn’t normally do so.
Ultracool dwarfs seem to fill a transition regime between brown dwarfs and stars. High precision observations of the ultracool dwarf J1835+3259 suggests its emission might be even more planet-like than originally thought.
Stars of various temperatures and sizes slow down at different rates– and to different extents. The authors of this paper address this distinction in a regime never before addressed observationally.
We don’t fully understand the emission processes in stellar flares. These authors try to get to the heart of the problem with multi-instrument observations.
