Zusammenfassung:
Coronal bright points (small-scale loop systems) in the solar atmosphere were studied
for more than 4 decades but the physical mechanism responsible for their formation
and evolution is still unknown. I will present two recent studies. The first investigates
the magnetic-field structure that hosts coronal bright points, and the second focuses
on the nature of mass ejections originating from coronal bright points. Magnetic field
data from HMI/SDO combined with imaging data from AIA/SDO are used together
with potential field extrapolations. Magneto-frictional relaxation simulations are also
tested for the first time aimed at understanding the formation of magnetic
configurations that may generate mini coronal mass ejections from bright points
