The First 3D Simulations of Carbon Burning in a Massive Star
Andrea Cristini, Casey Meakin, Raphael Hirschi +3
We present the first detailed three-dimensional hydrodynamic implicit large eddy simulations of turbulent convection for carbon burning. The simulations start with an initial radia…
Uncertainties in the production of p nuclides in thermonuclear supernovae determined by Monte Carlo variations
N. Nishimura, T. Rauscher, R. Hirschi +3
Thermonuclear supernovae originating from the explosion of a white dwarf accreting mass from a companion star have been suggested as a site for the production of nuclides. Such…
The Gaia-ESO Survey: open clusters in Gaia-DR1 - a way forward to stellar age calibration
S. Randich, E. Tognelli, R. Jackson +42
We describe the methodologies that, taking advantage of Gaia-DR1 and the Gaia-ESO Survey data, enable the comparison of observed open star cluster sequences with stellar evolutiona…
An Infrared Census of DUST in Nearby Galaxies with Spitzer (DUSTiNGS). IV. Discovery of High-Redshift AGB Analogs
M. L. Boyer, K. B. W. McQuinn, M. A. T. Groenewegen +13
The survey for DUST in Nearby Galaxies with Spitzer (DUSTiNGS) identified several candidate Asymptotic Giant Branch (AGB) stars in nearby dwarf galaxies and showed that dust can fo…
Evolutionary Constraints on the Long-period Subdwarf B Binary PG 1018-047
J. Deca, J. Vos, P. Németh +4
We have revisited the sdB+K-star long-period binary PG 1018-047 based on 20 new high-resolution VLT/UVES spectra that provided regular coverage over a period of more than 26 months…
Are some CEMP-s stars the daughters of spinstars?
Arthur Choplin, Raphael Hirschi, Georges Meynet +1
CEMP-s stars are long-lived low-mass stars with a very low iron content as well as overabundances of carbon and s-elements. Their peculiar chemical pattern is often explained by po…
