DESCRIPTION:Speakers: Alina Vishneva (DLNP JINR)\nCNO cycle of thermonucle
 ar reactions is one of the two main energy production mechanisms in the ma
 in sequence stars\, dominant in those heavier than the Sun.\nIn the contex
 t of solar physics\, despite its minor role in the energy production\, the
  CNO cycle is of a particular interest for it is directly related to the a
 bundance of heavy elements in the solar core.\nThe Borexino experiment pro
 vided the first experimental evidence of the CNO cycle in the Sun by detec
 ting neutrinos emitted in its reactions.\nThis measurement is made possibl
 e thanks to the unprecedented radiopurity of the detector and advanced met
 hods of constraining the correlated background allowing to pick out a rela
 tively weak and featureless CNO neutrino signal.\nIn this work we present 
 the recent update of the CNO neutrino flux measurement along with the firs
 t evaluation of the C and N abundance in the Sun based on the neutrino dat
 a only.\n\nhttps://indico.particle.mephi.ru/event/275/contributions/3215/
