Neutrino treatment in multidimensional astrophysical simulations : a new spectral scheme [PDF]

, 2014
Neutrinos play a central role in modern physics and astrophysics. Their extremely weak interaction rate with baryons and other leptons makes their detection on the Earth difficult and challenging.

Low Mass Stars or Intermediate Mass Stars? The Stellar Origin of Presolar Oxide Grains Revealed by Their Isotopic Composition

Frontiers in Astronomy and Space Sciences, 2021
Among presolar grains, oxide ones are made of oxygen, aluminum, and a small fraction of magnesium, produced by the 26Al decay. The largest part of presolar oxide grains belong to the so-called group 1 and 2, which have been suggested to form in Red Giant

Mixing and Magnetic Fields in Asymptotic Giant Branch Stars in the Framework of FRUITY Models

Universe, 2021
In the last few years, the modeling of asymptotic giant branch (AGB) stars has been much investigated, both focusing on nucleosynthesis and stellar evolution aspects. Recent advances in the input physics required for stellar computations made it possible

STELLAR NUCLEOSYNTHESIS IN THE HYADES OPEN CLUSTER [PDF]

The Astrophysical Journal, 2009
We report a comprehensive light element (Li, C, N, O, Na, Mg, and Al) abundance analysis of three solar-type main sequence (MS) dwarfs and three red giant branch (RGB) clump stars in the Hyades open cluster using high-resolution and high signal-to-noise spectroscopy.
