Astronomy Picture of the Day . ... 17.05.2001 . ... In a new twist to this solar neutrino saga, an analysis of data from the GALLEX / GNO neutrino detector finds a solar neutrino flux that varies over about 27 days ... approximately matching the Sun's rotation period. In fact, since different parts of the Sun rotate at different rates, the neutrino flux variations match most exactly the rotation rates of the areas shown in red on this colorful cross-sectional map of the solar interior rotation . ...

... Fall 2001 . ... With heavy water as its target medium the Sudbury Neutrino Observatory (SNO) is designed to study solar neutrinos by measuring both the total flux of 8B neutrinos through the neutral-current interaction as well as the electron-type neutrino flux via charged-current dissociation of deuterium. By comparing the electron neutrino flux to the total solar neutrino flux, SNO can make a unique study of the solar neutrino deficit and a model independent test for neutrino oscillations. ...

During the course of its evolution, the Sun has accreted substantial quantities of material in the form of asteroids, comets, planetesimals and proto-planets. This debris is poor in hydrogen and helium and has substantially enriched the metallicity of the solar surface which must consequently be higher than that of the unobserved core. ... The solution may also explain the Faint Young Sun paradox and the inclination of the solar equator relative to the ecliptic. ...

... The photon temperature now is T p = 2.728 K and the neutrino temperature now is 1.947 K. If neutrinos are massless then we can compute their equivalent mass density using rho = [Q/a 3 ]/c 2 = N n (2\sigma/c)(7/8)g f T n 4 where N n is the number of neutrino species: N n = 6 for 3 types of neutrinos and 3 types of anti-neutrinos. ... Because this behavior is caused by the thermal velocity of the neutrinos, this form of dark matter is called Hot Dark Matter . ...
