Dynamo Simulations Confirm Predominantly Toroidal Fields in Near-Core Region of an Intermediate-Mass Star
R. P. Ratnasingam, T. M. Rogers
Recent asteroseismic analysis of the main-sequence F star KIC 9244992 has revealed evidence for a strong, predominantly toroidal magnetic field in its deep radiative interior. Moti…
On the Geometry of the Near-Core Magnetic Field in Massive Stars
Rathish P. Ratnasingam, Philipp V. F. Edelmann, Dominic M. Bowman +1
It is well-known that the cores of massive stars sustain a stellar dynamo with a complex magnetic field configuration. However, the same cannot be said for the field's strength and…
On the photometric detection of Internal Gravity Waves in upper main-sequence stars I. Methodology and application to CoRoT targets
D. M. Bowman, C. Aerts, C. Johnston +8
Context. Main sequence stars with a convective core are predicted to stochastically excite Internal Gravity Waves (IGWs), which effectively transport angular momentum throughout th…
The shape of convective core overshooting from gravity-mode period spacings
M. G. Pedersen, C. Aerts, P. I. Pápics +1
The evolution of stars born with a convective core is highly dependent on the efficiency and extent of near core mixing processes, which effectively increases both the core mass an…
The hottest hot Jupiters may host Atmospheric Dynamos
T. M. Rogers, J. N. McElwaine
Hot Jupiters have proven themselves to be a rich class of exoplanets which test our theories of planetary evolution and atmospheric dynamics under extreme conditions. Here, we pres…
Kepler sheds new and unprecedented light on the variability of a blue supergiant: gravity waves in the O9.5Iab star HD 188209
C. Aerts, S. Simon-Diaz, S. Bloemen +12
Stellar evolution models are most uncertain for evolved massive stars. Asteroseismology based on high-precision uninterrupted space photometry has become a new way to test the outc…
Magnetic Effects in Hot Jupiter Atmospheres
Tamara M. Rogers, Thaddeus D. Komacek
We present magnetohydrodynamic (MHD) simulations of the atmospheres of hot Jupiters ranging in temperature from 1100-1800K. Magnetic effects are negligible in atmospheres with temp…
