Nuclear astrophysics and the trojan horse method
In this review, we discuss the new recent results of the Trojan Horse Method that is used to
determine reaction rates for nuclear processes in several astrophysical scenarios. The …

The Gaia-ESO survey: Mixing processes in low-mass stars traced by lithium abundance in cluster and field stars
Aims. We aim to constrain the mixing processes in low-mass stars by investigating the
behaviour of the Li surface abundance after the main sequence. We take advantage of the …
