Magnetism, dynamo action and the solar-stellar connection

AS Brun, MK Browning - Living Reviews in Solar Physics, 2017 - Springer
The Sun and other stars are magnetic: magnetism pervades their interiors and affects their
evolution in a variety of ways. In the Sun, both the fields themselves and their influence on …

Angular momentum transport in stellar interiors

C Aerts, S Mathis, TM Rogers - Annual Review of Astronomy …, 2019 - annualreviews.org
Stars lose a significant amount of angular momentum between birth and death, implying that
efficient processes transporting it from the core to the surface are active. Space …

Powering stellar magnetism: energy transfers in cyclic dynamos of Sun-like stars

AS Brun, A Strugarek, Q Noraz, B Perri… - The Astrophysical …, 2022 - iopscience.iop.org
We use the anelastic spherical harmonic code to model the convective dynamo of solar-type
stars. Based on a series of 15 3D MHD simulations spanning four bins in rotation and mass …

Asteroseismology of solar-type stars

RA García, J Ballot - Living Reviews in Solar Physics, 2019 - Springer
Until the last few decades, investigations of stellar interiors had been restricted to theoretical
studies only constrained by observations of their global properties and external …

The origin of weakened magnetic braking in old solar analogs

TS Metcalfe, AJ Finley, O Kochukhov… - The Astrophysical …, 2022 - iopscience.iop.org
The rotation rates of main-sequence stars slow over time as they gradually lose angular
momentum to their magnetized stellar winds. The rate of angular momentum loss depends …

Convective boundary mixing in main-sequence stars: theory and empirical constraints

EH Anders, MG Pedersen - Galaxies, 2023 - mdpi.com
The convective envelopes of solar-type stars and the convective cores of intermediate-and
high-mass stars share boundaries with stable radiative zones. Through a host of processes …

Rotation Periods, Inclinations, and Obliquities of Cool Stars Hosting Directly Imaged Substellar Companions: Spin–Orbit Misalignments Are Common

BP Bowler, QH Tran, Z Zhang, M Morgan… - The Astronomical …, 2023 - iopscience.iop.org
The orientation between a star's spin axis and a planet's orbital plane provides valuable
information about the system's formation and dynamical history. For non-transiting planets at …

3D simulations of magnetoconvection in a rapidly rotating supernova progenitor

V Varma, B Müller - Monthly Notices of the Royal Astronomical …, 2023 - academic.oup.com
We present a first 3D magnetohydrodynamic (MHD) simulation of oxygen, neon, and carbon
shell burning in a rapidly rotating core-collapse supernova progenitor. We also run a purely …

Simulations of solar and stellar dynamos and their theoretical interpretation

PJ Käpylä, MK Browning, AS Brun, G Guerrero… - Space Science …, 2023 - Springer
We review the state of the art of three dimensional numerical simulations of solar and stellar
dynamos. We summarize fundamental constraints of numerical modelling and the …

Stellar convective penetration: parameterized theory and dynamical simulations

EH Anders, AS Jermyn, D Lecoanet… - The Astrophysical …, 2022 - iopscience.iop.org
Most stars host convection zones in which heat is transported directly by fluid motion, but the
behavior of convective boundaries is not well-understood. Here, we present 3D numerical …
