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 ...

From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down ...

Starquake data is revealing ancient “fossil fields” responsible for stellar magnetism from birth through a star's final end.

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 ...

Learn how starquakes, subtle vibrations inside stars, revealed hidden magnetic fields in red giants and how this stellar archaeology links white dwarf magnetism to earlier stages of star evolution.

Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small ...
