Bridging planets and stars using scaling laws in anelastic spherical shell dynamos

Rakesh K. Yadav, Thomas Gastine, Ulrich R. Christensen +1

Dynamos operating in the interiors of rapidly rotating planets and low-mass stars might belong to a similar category where rotation plays a vital role. We quantify this similarity…

What controls the large-scale magnetic fields of M dwarfs?

T. Gastine, J. Morin, L. Duarte +3

Observations of active M dwarfs show a broad variety of large-scale magnetic fields encompassing dipole-dominated and multipolar geometries. We detail the analogy between some anel…

What controls the magnetic geometry of M dwarfs?

T. Gastine, J. Morin, L. Duarte +3

Context: observations of rapidly rotating M dwarfs show a broad variety of large-scale magnetic fields encompassing dipole-dominated and multipolar geometries. In dynamo models, th…

Surprisingly Weak Magnetism on Young Accreting Brown Dwarfs

Ansgar Reiners, Gibor Basri, Ulrich R. Christensen

We have measured the surface magnetic flux on four accreting young brown dwarfs and one non-accreting young very low-mass star utilizing high resolution spectra of absorption lines…
