15 صفحه اولGravitational helioseismology?
The magnitudes of the external gravitational perturbations associated with the normal modes of the Sun are evaluated to determine whether these solar oscillations could be observed with the proposed Laser Interferometer Space Antenna (LISA), a network of satellites designed to detect gravitational radiation. The modes of relevance to LISA—the l = 2, low-order p, f and g-modes—have not been conc...
متن کاملNeutrino Helioseismology
The observed deficit of B solar neutrinos may call for an improved standard model of the sun or an expanded standard model of particle physics (e.g., with neutrino masses and mixing). In the former case, contemporary fluid motions and thermal fluctuations in the sun’s core may modify nuclear reaction rates and restore agreement. To test this notion, we propose a search for short–term variations...
متن کاملHelioseismology and Solar Abundances
Helioseismology has allowed us to study the structure of the Sun in unprecedented detail. One of the triumphs of the theory of stellar evolution was that helioseismic studies had shown that the structure of solar models is very similar to that of the Sun. However, this agreement has been spoiled by recent revisions of the solar heavy-element abundances. Heavy element abundances determine the op...
متن کاملHelioseismology Present and Future
The subject of helioseismology is in a exciting phase of expansion. in terms of the methods being developed and applied, the new and challenging results coming out from the high-quality data that present observational campaigns, networks and missions are providing, the arrival of GONG+, the prospects for new missions including Solar Dynamics Observatory, and the recent groundbased results and e...
