摘要

太阳中微子的发现证实了太阳的内部运作大体上符合我们对聚变过程的理论理解。太阳中微子在发现中微子有质量和振荡方面也发挥了作用。我们将最新的太阳中微子数据与来自反应堆的其他振荡数据结合起来，以确定太阳的密度分布。我们在现有数据的基础上推导了约束条件，并展示了预期的改进：来自JUNO的更多反应堆中微子数据约束了真实的振荡参数；来自DUNE的更多太阳中微子数据将提供对hep中微子的关键测量。

Determining the density of the sun with neutrinos

The discovery of solar neutrinos confirmed that the inner workings of the Sun generally match our theoretical understanding of the fusion process. Solar neutrinos have also played a role in discovering that neutrinos have mass and that they oscillate. We combine the latest solar neutrino data along with other oscillation data from reactors to determine the Sun's density profile. We derive constraints given the current data and show the anticipated improvements with more reactor neutrino data from JUNO constraining the true oscillation parameters and more solar neutrino data from DUNE which should provide a crucial measurement of hep neutrinos.
