In this lecture I present the way stars can be modeled in two dimensions and especially the fluid flows that are driven by rotation. I discuss some of the various ways of taking into account turbulence and conclude this contribution by a short presentation of some of the first results obtained with the ESTER code on the modeling of interferometrically observed fast rotating early-type stars.

A. // Astronomy & Astrophysics / Astronomie et Astrophysique;Dec2013, Vol. 560, p1 

    Aims. We aim at constraining the angular momentum evolution of low-mass stars by measuring their rotation rates when they begin to evolve freely towards the zero-age main sequence (ZAMS), i.e., after the disk accretion phase has stopped. Methods. We conducted a multisite photometric monitoring...

    The deconfinement phase transition will lead to the release of latent heat during spins down of neutron stars if the transition is the first-order one. We have investigated the thermal evolution of neutron stars undergoing such deconfinement phase transition. The results show that neutron stars...

    The effects of rotation on the evolution and properties of low-mass stars are first discussed from the pre-main sequence to the red giant phase. We then briefly indicate how some observational constraints available for these stars can help us progress in our understanding of the dynamical...

    Rapidly rotating massive stars are currently one of the most promising ways of explaining the high N/O abundances measured in normal metal poor stars. Here we show the predicted impact of fast rotators on the 12C/13C ratio at very low metallicities. We show that upon the inclusion of fast...

    Axial rotation of a star plays an important role in its evolution, physical conditions in its atmosphere and the appearance of its spectrum. We analyzed CCD spectra of nine stars for which the projected rotational velocity derived from the Ca II line at λ 3933 Å was remarkably lower than...

    We review the significant role played by red supergiants (RSGs) in stellar populations, and some challenges and questions they raise for theoretical stellar evolution. We present how metallicity and rotation modify the way stars go to the red part of the Hertzsprung-Russell diagram or come back...

    Aims. Observations show nebulae around some massive stars but not around others. If observed, their chemical composition is far from homogeneous. Our goal is to put these observational features into the context of the evolution of massive stars and their circumstellar medium (CSM) and, more...
