Measuring the extent of convective cores in low-mass stars using Kepler data: towards a calibration of core overshooting
S. Deheuvels, I. Brandão, V. Silva Aguirre +5
Our poor understanding of the boundaries of convective cores generates large uncertainties on the extent of these cores and thus on stellar ages. Our aim is to use asteroseismology…
Constraints to dark-matter properties from asteroseismic analysis of KIC 2009504
Isa M. Brandão, Jordi Casanellas
Asteroseismology can be used to constrain some properties of dark-matter (DM) particles (Casanellas & Lopes, 2013). In this work, we performed an asteroseismic modelling of the mai…
Stellar convective cores as dark matter probes
Jordi Casanellas, Isa M. Brandão, Yveline Lebreton
The recent detection of a convective core in a main-sequence solar-type star is used here to test particular models of dark matter (DM) particles, those with masses and scattering…
Inferring properties of small convective cores in main-sequence solar-like pulsators
I. M. Brandão, M. S. Cunha, J Christensen-Dalsgaard
This work concerns the study of the properties of convective cores in main-sequence models of solar-like pulsators and what information they may hold about stellar ages. We verifie…
On the inference of stellar ages and convective-core properties in main-sequence solar-like pulsators
I. M. Brandão, M. S. Cunha, J. Christensen-Dalsgaard
Particular diagnostic tools may isolate the signature left on the oscillation frequencies by the presence of a small convective core. Their frequency derivative is expected to prov…
Testing excitation models of rapidly oscillating Ap stars with interferometry
M. S. Cunha, D. Alentiev, I. M. Brandão +1
Rapidly oscillating Ap stars are unique objects in the potential they offer to study the interplay between a number of important physical phenomena, in particular, pulsations, magn…
