(American Astronomical SocietyIOP Publishing, 1996-01-10)By mimicking the effects of a magnetic field on the interior structure of a solar model, observed changes in p-mode frequencies over the course of the solar cycle are explained in terms of a change in the intensity and ...
-
(Oxford University PressRoyal Astronomical Society, 2013-04-12)We perform a Bayesian grid-based analysis of the solar l = 0, 1, 2 and 3 p modes obtained via BiSON in order to deliver the first Bayesian asteroseismic analysis of the solar composition problem. We do not find decisive ...
-
(American Astronomical Society and IOP Publishing, 2003-07-10)We construct models of the structure and evolution of the Sun which include variable magnetic fields and turbulence. The magnetic effects are (1) magnetic pressure, (2) magnetic energy, and (3) magnetic modulation to ...
-
(American Astronomical Society, 2004-01)We describe a method to match stellar models to a set of low-l p-mode oscillation frequencies. The method provides a quality of fit measure similar to that obtained from a [subscript X][superscript 2] fit. With a sufficiently ...
-
(American Astronomical Society, 1995-06-10)We have studied the importance of the combined effects of rotation, diffusion, and convective overshoot on the p-mode oscillation spectrum and the neutrino flux of the standard solar model. To isolate the various physical ...
-
(American Astronomical Society, 1999-05-20)Kim and Chan have completed a three-dimensional numerical simulation of the interaction between turbulent convection and radiation in and above the highly superadiabatic layer (SAL) in the Sun. They have shown that the ...
-
(American Astronomical Society, 1997-01-10)The effect of adjustments to the superadiabatic layer (SAL) in a model of the Sun on the p-mode oscillation frequencies has been studied. Numerical simulations of solar convection by Kim and coworkers have shown that the ...
-
(American Astronomical Society, 1997-08)The structure of the deep interior of a variety of standard and nonstandard solar models constrained by the low-l p-mode oscillation data from GONG are presented. For standard models, we show that the effects of both helium ...
-
(American Astronomical Society, 1996-05-20)The OPAL equation-of-state tables and the MHD equation-of-state tables are utilized in the calculation of new standard solar models that also include helium diffusion. The structure of the models and their l = 0-100 p-mode ...
-
(American Astronomical Society, 1998-05-10)We compare the p-mode oscillation spectra of solar models, constructed under the assumption that the universal gravitation constant G varied monotonically over the course of the solar lifetime, to the most recent solar ...
