Understanding the Sun: Borexino [PDF]

Journal of Physics: Conference Series, 2010
Solar neutrinos have been detected over the past 40 years providing the first evidence of physics beyond the Standard Model for elementary particle interactions. The hypothesis of neutrino oscillations has offered a solution to the long-standing solar neutrino problem (missing solar neutrinos).

Borexino Results on Neutrinos from the Sun and Earth

Universe, 2021
Borexino is a 280-ton liquid scintillator detector located at the Laboratori Nazionali del Gran Sasso in Italy. Since the start of its data-taking in May 2007, it has provided several measurements of low-energy neutrinos from various sources. At the base

Abundances of Uranium and Thorium Elements in Earth Estimated by Geoneutrino Spectroscopy

Geophysical Research Letters, Volume 49, Issue 16, 28 August 2022., 2022
Abstract The decay of the primordial isotopes 238U, 235U, 232Th, and 40K has contributed to the terrestrial heat budget throughout the Earth's history. Hence, the individual abundance of those isotopes are key parameters in reconstructing contemporary Earth models.

Von Wasserstoff bis Eisen, Nickel und Zink

Physik in unserer Zeit, Volume 53, Issue 4, Page 182-189, July 2022., 2022
Woraus besteht die Welt? Die Philosophen der Antike postulierten vier oder fünf Elemente. In der Neuzeit erweiterten Dimitri Mendelejew und Lothar Meyer dies auf eine rasch wachsende Tabelle der chemischen Elemente. Kirchhoff und Bunsen entdeckten Fraunhofer‐Linien im Sonnenspektrum, denen zufolge die auf der Erde existierenden Elemente auch in Sternen

Calculated Event Rates for Axion Detection via Atomic and Nuclear Processes

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022
The possibility of detection of 5.5 MeV and 14.4 keV solar axions by observing axion‐induced nuclear and atomic transitions is investigated. The presence of nuclear transitions between spin orbit partners can be manifested by the subsequent deexcitation via gamma ray emissions.

Erstmalige Beobachtung des CNO‐Zyklus

Physik in unserer Zeit, Volume 52, Issue 2, Page 73-79, March 2021., 2021
Vor 80 Jahren schlugen Carl Friedrich von Weizsäcker und Hans Bethe den sogenannten CNO‐Zyklus als mögliche Energiequelle für die Sterne vor. Bis vor kurzem ließ sich dieser Fusionsmechanismus in der Sonne jedoch experimentell nicht nachweisen. Dies gelang jetzt mit dem Neutrinodetektor Borexino.

Search for low-energy signals from fast radio bursts with the Borexino detector

European Physical Journal C: Particles and Fields, 2022
The search for neutrino events in correlation with 42 most intense fast radio bursts (FRBs) has been performed using the Borexino dataset from 05/2007 to 06/2021. We have searched for signals with visible energies above 250 keV within a time window of $$\

Borexino

Nuclear Physics B - Proceedings Supplements, 2011
Borexino is a massive calorimetric liquid scintillation detector whose installation has been completed in the underground Gran Sasso Laboratory. The focus of the experiment is on the direct and real time measurement of the flux of neutrinos produced in the $^{7}Be$ electron capture reaction in the Sun. Furthermore, recent studies about the reduction of
