Description
We describe the presence of wave front dislocations in
magnetohydrodynamic waves in stratified stellar atmospheres. Scalar
dislocations such as edges and vortices can appear in Alfvén
waves, as well as in general magnetoacoustic waves. We detect those
dislocations in observations of magnetohydrodynamic waves in sunspots in
the solar chromosphere. Through the measured charge of all the
dislocations observed, we can give for the first time estimates of the
modal contribution in the waves propagating along magnetic fields in
solar sunspots.

Solar and Stellar Magnetism
Magnetic fields are at the base of star formation and stellar structure and evolution. When stars are born, magnetic fields brake the rotation during the collapse of the mollecular cloud. In the end of the life of a star, magnetic fields can play a key role in the form of the strong winds that lead to the last stages of stellar evolution. During
