Early-type stars show a bimodal distribution of magnetic field strengths, with some showing very strong fields (≳1 kG) and others very weak fields (≲10 G). Recently, we proposed that this reflects the processing or lack thereof of fossil fields by subsurface convection zones. Stars with weak fossil fields process these at the surface into even weaker dynamo-generated fields, while in stars with stronger fossil fields magnetism inhibits convection, allowing the fossil field to remain as is. We… 


The Origin of the Bimodal Distribution of Magnetic Fields in Early-type Stars
In early-type stars a fossil magnetic field may be generated during the star formation process or be the result of a stellar merger event. Surface magnetic fields are thought to be erased by
Magnetic fields in non-convective regions of stars
Whether the Sun could harbour a magnetic field in its core is discussed, and possible dynamo mechanisms that run on differential rotation rather than convection are looked at.
Asteroseismology can reveal strong internal magnetic fields in red giant stars
It is demonstrated that strong magnetic fields in the cores of red giant stars can be identified with asteroseismology and depressed dipole stellar oscillation modes, arising from a magnetic greenhouse effect that scatters and traps oscillation-mode energy within the core of the star.
Magnetic spots on hot massive stars
Context. Hot luminous stars show a variety of phenomena in their photospheres and winds which still lack clear physical explanation. Among these phenomena are photospheric turbulence, line profile
On magnetic inhibition of photospheric macroturbulence generated in the iron-bump opacity zone of O-stars
Massive, hot OB-stars show clear evidence of strong macroscopic broadening (in addition to rotation) in their photospheric spectral lines. This paper examines the occurrence of such
Forward seismic modeling of the pulsating magnetic B-type star HD 43317
The large-scale magnetic fields detected at the surface of about 10% of hot stars extend into the stellar interior, where they may alter the structure. Deep inner regions of stars are only observable
Physical Processes in Magnetically Driven Flares on the Sun, Stars, and Young Stellar Objects
The first flare on the Sun was observed exactly 150 years ago. During most of the long history, only secondary effects have been noticed, so flares remained a riddle. Now the primary flare products,
Slowing the spins of stellar cores
The angular momentum (AM) evolution of stellar interiors, along with the resulting rotation rates of stellar remnants, remains poorly understood. Asteroseismic measurements of red giant stars

Massive stars are important metal factories in the Universe. They have short and energetic lives, and many of them inevitably explode as a supernova and become a neutron star or black hole. In turn,
Solar Dynamo Theory
The Sun's magnetic field is the engine and energy source driving all phenomena collectively defining solar activity, which in turn structures the whole heliosphere and significantly impacts Earth's
