Abstract The theoretical oscillation frequencies of even the best asteroseismic models solar-like oscillators show significant differences from observed frequencies. Structure inversions seek to use these frequency infer underlying in stellar structure. While used extensively study Sun, structure inversion results for other stars have so far been limited. Applying sound speed more allows us probe theory over a larger range conditions, as well look overall patterns that may hint at deficits...
Asteroseismic inferences of main-sequence solar-like oscillators often rely on best-fit models. However, these models cannot fully reproduce the observed mode frequencies, suggesting that internal structure model does not match star. inversions provide a way to test interior our stellar Recently, inversion techniques were used study 12 stars with radiative cores. In this work, we extend analysis 43 convective cores by Kepler look for differences in sound speed profiles inner 30% star radius....
The concept of putting a neutrino detector in close orbit the sun has been unexplored until very recently. primary scientific return is to vastly enhance our understanding solar interior, which major NASA goal. Preliminary calculations show that such spacecraft, if properly shielded, can operate space environments while taking data from interactions. These interactions be distinguished random background rates electromagnetic emissions, galactic charged cosmic-rays, and gamma-rays by using...
