Very Metal-Poor Outer-Halo Stars with Round Orbits

Kohei Hattori, Yuzuru Yoshii, Timothy C. Beers +2

The orbital motions of halo stars in the Milky Way reflect the orbital motions of the progenitor systems in which they formed, making it possible to trace the mass-assembly history…

The 12C + 12C reaction and the impact on nucleosynthesis in massive stars

M. Pignatari, R. Hirschi, M. Wiescher +7

Despite much effort in the past decades, the C-burning reaction rate is uncertain by several orders of magnitude, and the relative strength between the different channels 12C(12C,a…

Is γ-ray emission from novae affected by interference effects in the 18F(p,α)15O reaction?

A. M. Laird, A. Parikh, A. St. J. Murphy +14

The 18F(p,α)15O reaction rate is crucial for constraining model predictions of the γ-ray observable radioisotope 18F produced in novae. The determination of this rate is challengin…

First stars XVI. STIS/HST abundances of heavy-elements in the uranium-rich star CS 31082-001

C. Siqueira Mello, M. Spite, B. Barbuy +14

Detailed abundances of the elements produced by r-process nucleosynthesis in various circumstances are our best observational clues to their origin, since the site(s) of r-element…

The Impact of Helium-Burning Reaction Rates on Massive Star Evolution and Nucleosynthesis

Christopher West, Alexander Heger, Sam M. Austin

We study the sensitivity of presupernova evolution and supernova nucleosynthesis yields of massive stars to variations of the helium-burning reaction rates within the range of thei…
