Definition of solar neutrino unit in US English:
solar neutrino unit
nounˌsōlər n(y)o͞oˈtrēnō ˌyo͞onət
Astronomy A unit used in expressing the detected flux of neutrinos from the sun, equal to 10⁻³⁶ neutrino captures per target atom per second.
Example sentencesExamples
- Neutrino astronomers often report their results in terms of solar neutrino units, or SNUs.
- The latest experimental results correspond to 1 SNU, whereas solar models yield values higher by one order of magnitude.
- This has shown neutrino rates that fluctuate around an average of 83 solar neutrino units.
- The GALLEX experimenters report observation of 83 19 8 SNU (solar neutrino units, the standard measure of solar neutrino flux) while standard astrophysical models of the fusion processes in the sun would predict about 128 SNU.
- The standard solar model predicts that a gallium detector should pick up between 125 and 132 solar neutrino units for all neutrinos from the various reactions that can occur in the Sun.
