DESCRIPTION:Nuclear astrophysics is a fascinating discipline which aims to
  explain – quantitatively andqualitatively – the observed abundance of
  elements in the cosmos. Current nucleosynthesis modelsindicate that light
  elements until the iron peak are produced through progressive stellar bur
 ning\,while those beyond are mainly generated by neutron capture processes
 . The correspondingnetwork models are sensitive to atomic/nuclear properti
 es of the isotopes and the underlyingastrophysical conditions. Since nucle
 osynthesis primarily occurs in stars which are high energydensity plasmas\
 , it is necessary to factor in the effect of the plasma on these data for 
 accuratereconstruction of elemental abundances.The PANDORA facility\, curr
 ently under realisation at INFN-LNS\, aims to investigate theseproperties 
 inside a laboratory magnetoplasma emulating the stellar interior. While th
 e primarygoal of the facility is to measure β-decay rates of isotopes in 
 a hot plasma\, the density andtemperature achievable also make it a prospe
 ctive testbench to measure cross sections of atomicreactions such as colli
 sional ionisation\, excitation and recombination. In this seminar\, I will
 provide an overview of the physics and technology behind PANDORA. In parti
 cular\, I will discussthe properties of the plasma\, the interplay between
  nuclear and atomic data\, and the plasma kineticsimulations we have devel
 oped to model observables connected to the variation of decay rates andato
 mic reaction cross sections. The experimental data from the facility will 
 serve as useful inputsin s-process nucleosynthesis models\, and for spectr
 al reconstruction of kilonovae in the nebularphase.\n\nhttps://indico.fysi
