The core/envelope symmetry in pulsating stars
We demonstrate that there is an inherent symmetry in the way high-overtone stellar pulsations sample the core and the envelope, which can potentially lead to an ambiguity in the asteroseismologically derived locations of internal structures. We provide an intuitive example of the source of this symmetry by analogy with a vibrating string. For the stellar case, we focus on the white dwarf stars,...
متن کاملTwo-fluid atmosphere for relativistic stars
We have extended the Vaidya radiating metric to include both a radiation fluid and a string fluid. This paper expands our brief introduction to extensions of the Schwarzschild vacuum which appeared in 1998 Phys. Rev. D 57 R5945. Assuming diffusive transport for the string fluid, we find new analytic solutions of Einstein’s field equations. PACS numbers: 0420J, 0440D, 9760
متن کاملSuper-resolution imaging of neuronal dense-core vesicles.
Detection of fluorescence provides the foundation for many widely utilized and rapidly advancing microscopy techniques employed in modern biological and medical applications. Strengths of fluorescence include its sensitivity, specificity, and compatibility with live imaging. Unfortunately, conventional forms of fluorescence microscopy suffer from one major weakness, diffraction-limited resoluti...
متن کاملA Competitive Model of (Super)Stars
Following Rosen [1981], superstar effects (earnings convex in quality and a few firms reaping a large share of market earnings) occur with imperfect substitution between sellers, low (and possibly declining) marginal cost of output, and marginal cost falling as quality increases. However, markets without such characteristics have superstar effects, and the main result from the superstar model —...
متن کاملBreaking the core-envelope symmetry in p-mode pulsating stars
It has been shown that there is a potential ambiguity in the asteroseismic determination of the location of internal structures in a pulsating star (Montgomery et al. 2003). We show how, in the case of high-order non-radial acoustic modes, it is possible to remove this ambiguity by considering modes of different degree. To support our conclusions we have investigated the seismic signatures of s...
