Surface convection: from the Sun to red giant stars
Laurent Piau, Pierre Kervella, Sami Dib +1
We check how the change in surface conditions between the Sun and red giant branch stars changes the characteristic surface convection length scale to be used in models. We investi…
The Dependence of the Galactic Star Formation Laws on Metallicity
Sami Dib, Laurent Piau, Subhanjoy Mohanty +1
We describe results from semi-analytical modelling of star formation in protocluster clumps of different metallicities. In this model, gravitationally bound cores form uniformly in…
The long term dynamics of the solar radiative zone associated to new results from SoHO and young solar analogs
Sylvaine Turck-Chieze, Sebastien Couvidat, Antonio Eff-Darwich +6
The Standard Solar Model (SSM) is no more sufficient to interpret all the observations of the radiative zone obtained with the SoHO satellite. We recall our present knowledge of th…
The solar energetic balance revisited by young solar analogs, helioseismology and neutrinos
Sylvaine Turck-Chieze, Laurent Piau, Sébastien Couvidat
The energetic balance of the Standard Solar Model (SSM) results from an equilibrium between nuclear energy production, energy transfer, and photospheric emission. In this letter, w…
Star formation efficiency as a function of metallicity: from star clusters to galaxies
Sami Dib, Laurent Piau, Subhanjoy Mohanty +1
We explore how the star formation efficiency in a protocluster clump is regulated by metallicity dependent stellar winds from the newly formed massive OB stars (Mstar >5 Msol). The…
The dynamics of the radiative zone of the Sun
S Turck-Chieze, S Couvidat, V Duez +4
Helioseismology puts strong constraints on the internal sound speed and on the rotation profile in the radiative zone. Young stars of solar type are more active and faster rotators…
