Asteroseismology of massive stars: new insights of stellar interiors from their pulsations [PDF]
, 2021 Massive stars are important metal factories which provide energy and chemical feedback to their surroundings. However, stellar evolution models currently contain large theoretical uncertainties for physical mechanisms at work in the deep interiors of ...

Detailed chemical compositions of planet-hosting stars: II. Exploration of the interiors of terrestrial-type exoplanets [PDF]
, 2022 International audienceA major goal in the discovery and characterisation of exoplanets is to identify terrestrial-type worlds that are similar to (or otherwise distinct from) our Earth.

Charge densities in stellar interiors: a step towards the understanding ofthe rotation–activity–age relationship for low-mass stars [PDF]
, 2023 Although space-based missions such as CoRoT, Kepler/K2, TESS, and the future data from the PLATO mission have provided a wealth of observational data, the connections between rotation, magnetic activity, and the thermodynamic properties of stellar ...

Cooling rates of neutron stars and the young neutron star in the Cassiopeia A supernova remnant [PDF]
, 2010 We explore the thermal state of the neutron star in the Cassiopeia A supernova remnant using the recent result of Ho & Heinke that the thermal radiation of this star is well described by a carbon atmosphere model and the emission comes from the ...

The Interiors of Neutron Stars [PDF]
, 2023 Neutron stars are some of the most exotic and mysterious objects in the universe, whose structure, composition and evolution are still being uncovered. The remote nature and small size of these compact objects make direct observation a challenge, forcing

3-D reconstructions of active stars [PDF]
, 2012 Stars are usually faint point sources and investigating their surfaces and interiors observationally is very demanding. Here I give a review on the state-of-the-art observing techniques and recent results on studying interiors and surface features of ...

Dynamics of fossil magnetic fields in massive star interiors [PDF]
, 2010 In this talk, I review the different MHD processes, which take place in massive star interiors. First, I describe MHD instabilities, which act on magnetic fields in stellar radiation zones, and the dynamo action in massive stars that give strong ...

Asteroseismology of solar-type stars [PDF]
, 2019 International audienceUntil the last few decades, investigations of stellar interiors had been restricted to theoretical studies only constrained by observations of their global properties and external characteristics.

Internal transport processes in stars and the Sun: some updates [PDF]
, 2022 Internal transport processes are known to be at play in (cool) stars of all masses, and manifest through their impact on the surface chemical, rotational and magnetic evolution of stars, as well as through their shaping of the chemical and rotation ...
