The seismic structure of the sun
Gough, DO; Kosovichev, AG; Toomre, J; Anderson, E; Antia, HM; Basu, S; Chaboyer, B; Chitre, SM; ChristensenDalsgaard, J; Dziembowski, WA; EffDarwich, AGlobal Oscillation Network Group data reveal that the internal structure of the sun can be well represented by a calibrated standard model. However, immediately beneath the convection zone and at the edge of the energy-generating core, the sound-speed variation is somewhat smoother in the sun than it is in the model. This could be a consequence of chemical inhomogeneity that is too severe in the model, perhaps ...

Monteiro, MJPFG; ChristensenDalsgaard, J; Thompson, MJSome alternatives to the traditional mixing-length theory (MLT) have recently been proposed for modelling convective heat transport inside stars. The ideal formulation is one that does not involve any free parameters. However, in our present state of ignorance we still need at least one free parameter in order to build solar models with the correct radius. Having adjusted this parameter (e.g. the mixing-length ...
