Ongoing Space Physics - Astrophysics Connections
نویسنده
چکیده
I review several ongoing connections between space physics and astrophysics: a) Measurements of energetic particle spectra have confirmed theoretical prediction of the highest energy to which shocks can accelerate particles, and this has direct bearing on the origin of the highest energy cosmic rays. b) Mass ejection in solar flares may help us understand photon ejection in the giant flares of magnetar outbursts. c) Measurements of electron heat fluxes in the solar wind can help us understand whether heat flux in tenuous astrophysical plasma is in accordance with the classical Spitzer-Harm formula or whether it is reduced well below this value by plasma instabilities.

متن کاملTopics in Neutrino Astrophysics
Part of the interest in neutrino astrophysics has to do with the fascinating interplay between nuclear and particle physics issues — e.g., whether neutrinos are massive and undergo flavor oscillations, whether they have detectable electromagnetic moments, etc. — and astrophysical phenomena, such as the clustering of matter on large scales, the mechanisms responsible for the synthesis of nuclei,...
