In main-sequence stars, the periods of high-order gravity modes are sensitive probes of stellar cores and, in particular, of the chemical composition gradient that develops near the outer edge of the convective core. We present an analytical approximation of high-order g modes that takes into account the effect of the μ gradient near the core. We show that in main-sequence models, similarly to the case of white dwarfs, the periods of high-order gravity modes are accurately described by a… Expand
On the shape of core overshooting in stellar model computations, and asteroseismic tests
Slowly pulsating B stars (SPB) and $\gamma$ Dor stars pulsate in high-order gravity (g-) modes. The frequencies of g-modes are sensitive to the detailed structure and evolution history of starsExpand
The shape of convective core overshooting from gravity-mode period spacings
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 and main-sequenceExpand
Probing tiny convective cores with the acoustic modes of lowest degree
Solar-like oscillations are expected to be excited in stars of up to about 1.6 solar masses. Most of these stars will have convective cores during their main-sequence evolution. At the edges of theseExpand
Observations of the pulsations of stars can be used to infer their interior structure and test theoretical models. The main-sequence γ Doradus (Dor) and δ Scuti (Sct) stars with masses 1.2-2.5 M ☉Expand
Deviations from a uniform period spacing of gravity modes in a massive star
The detection of numerous gravity modes in a young star with a mass of about seven solar masses is reported, and the mean period spacing allows the extent of the convective core to be estimated and the clear periodic deviation from the mean constrains the location of the chemical transition zone to be at about 10 per cent of the radius.

The effects of near-core convective shells on the gravity modes of the subdwarf B pulsator KIC 10553698A
KIC 10553698A is a hot pulsating subdwarf B (sdB) star observed by the Kepler satellite. It exhibits dipole (l = 1) and quadrupole (l = 2) gravity modes with a clear period spacing structure. TheExpand
Evolution of the gravity offset of mixed modes in RGB stars
Observations of mixed modes in evolved low-mass stars enable us to probe the properties of not only the outer envelope of these stars, but also their deep layers. Among the seismic parametersExpand
Rotation of the convective core in γ Dor stars measured by dips in period spacings of g modes coupled with inertial modes
The relation of period spacing (ΔP) versus period (P) of dipole prograde g modes is known to be useful to measure rotation rates in the g-mode cavity of rapidly rotating γ Dor and slowly pulsating BExpand
Probing the cores of solar-like pulsators
Stars slightly more massive than the Sun develop small convective cores during their main sequence phase of evolution. The edges of these convective cores are associated with rapid variations in theExpand
Kepler red-clump stars in the field and in open clusters: constraints on core mixing
Convective mixing in helium-core-burning (HeCB) stars is one of the outstanding issues in stellar modelling. The precise asteroseismic measurements of gravity-mode period spacing (dσ1) have openedExpand
