Solar prominences: 'double, double ... boil and bubble'
Rony Keppens, Chun Xia, Oliver Porth
Observations revealed rich dynamics within prominences, the cool 10,000 K, macroscopic (sizes of order 100 Mm) "clouds" in the million degree solar corona. Even quiescent prominenc…
Interacting tilt and kink instabilities in repelling current channels
Rony Keppens, Oliver Porth, Chun Xia
We present a numerical study in resistive magnetohydrodynamics where the initial equilibrium configuration contains adjacent, oppositely directed, parallel current channels. Since…
Simulating the in situ condensation process of solar prominences
Chun Xia, Rony Keppens, Patrick Antolin +1
Prominences in the solar corona are hundredfold cooler and denser than their surroundings, with a total mass of 1.e13 up to 1.e15 g. Here we report on the first comprehensive simul…
Jet formation from massive young stars: Magnetohydrodynamics versus radiation pressure
Bhargav Vaidya, Christian Fendt, Henrik Beuther +1
Observations indicate that outflows from massive young stars are more collimated during their early evolution compared to later stages. Our paper investigates various physical proc…
