Magnetic stars as a research area focuses on the origin, structure, and evolution of stellar magnetic fields and their impact on stellar physics. It encompasses observational and theoretical studies of magnetic field generation via dynamo action or fossil fields, field topology and strength across different spectral types, and magnetically induced phenomena such as starspots, flares, and coronal activity. The field also investigates magnetic braking, angular momentum loss, and interactions between stellar magnetism and circumstellar environments, including magnetospheres and stellar winds, with implications for stellar evolution, variability, and exoplanetary space weather.
For the first time, new theoretical models, published in Astronomy & Astrophysics, connect the magnetism at the surface of long-dead stellar remnants (white dwarfs) with recent evidence of magnetism at the cores of their ...

Pulsars are ultra-dense, rapidly spinning, and highly magnetized remnants of dead stars. They act like cosmic lighthouses, sending out regular pulses of radio waves and sometimes gamma rays in beams that sweep across the ...

In a new study published in Physical Review Letters, scientists have performed the first global simulations of monster shocks—some of the strongest shocks in the universe—revealing how these extreme events in magnetar magnetospheres ...
For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the fundamental driver of solar activity. The research, published in The Astrophysical Journal Letters, should ...
An international team, led by Instituto de Astrofísica e Ciências do Espaço (IA) researcher Ângela Santos, has made the first measurement of the magnetic field of β Hydri, a nearby aged solar analog subgiant star. This result, ...
