Photometric detection of internal gravity waves in early-type stars observed by CoRoT
D. M. Bowman, C. Aerts, C. Johnston +8
Early-type stars are predicted to excite an entire spectrum of internal gravity waves (IGWs) at the interface of their convective cores and radiative envelopes. Numerical simulatio…
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…
K2 observations of the rapidly oscillating Ap star 33 Lib (HD 137949): new frequencies and unique non-linear interactions
Daniel L. Holdsworth, Margarida S. Cunha, Hiromoto Shibahashi +2
We present the analysis of K2 short cadence data of the rapidly oscillating Ap (roAp) star, 33 Librae (HD 137949). The precision afforded to the K2 data allow us to identify at lea…
LCO observations of a super-critical distorted pulsation in the roAp star J0855 (TYC 2488-1241-1)
Daniel L. Holdsworth, Hideyuki Saio, Ramotholo R. Sefako +1
We report the results of a 60-hr photometric campaign of a rapidly oscillating Ap star, J0855 (TYC 2488-1241-1). We have utilised the multi-site Las Cumbres Observatory's (LCO) 0.4…
On the sensitivity of gravito-inertial modes to differential rotation in intermediate-mass main-sequence stars
T. Van Reeth, J. S. G. Mombarg, S. Mathis +9
Context. While rotation has a major impact on stellar structure and evolution, its effects are not well understood. Thanks to high- quality and long timebase photometric observatio…
Forward asteroseismic modeling of stars with a convective core from gravity-mode oscillations: parameter estimation and stellar model selection
C. Aerts, G. Molenberghs, M. Michielsen +13
We propose a methodological framework to perform forward asteroseismic modeling of stars with a convective core, based on gravity-mode oscillations. These probe the near-core regio…
