Rotation suppresses giant-scale solar convection
The observational absence of giant convection cells near the Sun's outer surface is a long-
standing conundrum for solar modelers. We herein propose an explanation. Rotation …

Heat transport and convective velocities in compositionally driven convection in neutron star and white dwarf interiors
We investigate heat transport associated with compositionally driven convection driven by
crystallization at the ocean–crust interface in accreting neutron stars, or growth of the solid …

Asteroseismic inference of the near-core magnetic field strength in the main-sequence B star HD 43317
About 10 per cent of intermediate-and high-mass dwarf stars are observed to host a strong
large-scale magnetic field at their surface, which is thought to be of fossil field origin …
