Measuring solar neutrinos over Gigayear timescales with Paleo Detectors

In a recent study, researchers Natalia Tapia Arellano and Shunsaku Horiuchi have proposed using paleo detectors to measure the solar neutrino flux over gigayear timescales. This could provide valuable insights into the Solar Standard Model as well as studies of the Earth's long-term climate. Paleo detectors are naturally occurring minerals that record neutrino-induced recoil tracks over geological times. The researchers demonstrate the feasibility of measuring the time-evolution of the $^8$B solar neutrino flux over gigayear timescales using these detectors. They explore suitable minerals and identify track lengths of 15--30 nm as a practical window to detect the $^8$B solar neutrino flux. The team suggests that a collection of ultra-radiopure minerals of different ages, each weighing around 0.1 kg, can be used to probe the rise of the $^8$B solar neutrino flux over the recent gigayear of the Sun's evolution. By analyzing these minerals, they aim to distinguish between models of the solar abundance problem based on time-integrated tracks induced by the $^8$B solar neutrino flux. This research presents an exciting opportunity to gain new insights into our understanding of both astrophysics and climate science. By measuring the solar neutrino flux over such vast timescales, we can gain a deeper understanding of how our Sun has evolved and how it may continue to change in future.

Using Paleo Detectors to Measure Solar Neutrino Flux Over Gigayear Timescales

Recent research by Natalia Tapia Arellano and Shunsaku Horiuchi has proposed a new method for measuring the solar neutrino flux over gigayear timescales. This could provide valuable insights into both astrophysics and climate science, as well as our understanding of the Solar Standard Model. In this article, we will explore what paleo detectors are, how they can be used to measure solar neutrino flux over such vast timescales, and what implications this research may have for our understanding of the Sun's evolution.

What are Paleo Detectors?

Paleo detectors are naturally occurring minerals that record neutrino-induced recoil tracks over geological times. These minerals contain trace elements which can detect these particles when they interact with them. The researchers suggest that track lengths of 15–30 nm are practical windows to detect the $^8$B solar neutrino flux from our Sun.

By analyzing these minerals, they aim to distinguish between models of the solar abundance problem based on time-integrated tracks induced by the $^8$B solar neutrino flux.

Implications for Astrophysics and Climate Science

By measuring the solar neutrino flux over such vast timescales, we can gain a deeper understanding of how our Sun has evolved and how it may continue to change in future – providing valuable insights into both astrophysics and climate science alike. This research presents an exciting opportunity to gain new knowledge about our universe and its long-term history – giving us unprecedented insight into one of its most important stars: Our own sun!
