    Differential rotation, radiative equilibrium, and local hydrodynamic stability in stellar interiors by Caleo, A

    Published 2016
    “…In particular:</p> <ol type="a"><li>The data from helioseismology show that the upper radiative zone of the Sun is in near-uniform rotation, but they have a significant uncertainty. …”

    Solar Surface Convection by Nordlund Åke, Stein Robert F., Asplund Martin

    Published 2009-04-01
    “…One of the most noteworthy results has been a significant reduction in recent years in the derived solar C, N, and O abundances with far-reaching consequences, not the least for helioseismology.Convection in the solar surface layers is also of great importance for helioseismology in other ways; excitation of the wave spectrum occurs primarily in these layers, and convection influences the size of global wave cavity and, hence, the mode frequencies. …”

    Large-Scale Dynamics of the Convection Zone and Tachocline by Miesch Mark S.

    Published 2005-04-01
    “…The past few decades have seen dramatic progress in our understanding of solar interior dynamics, prompted by the relatively new science of helioseismology and increasingly sophisticated numerical models. …”

    Radiation burnthrough measurements to infer opacity at conditions close to the solar radiative zone–convective zone boundary by Hoarty, DJ, Morton, J, Rougier, JC, Rubery, M, Opachich, YP, Swatton, D, Richardson, S, Heeter, RF, McLean, K, Rose, SJ, Perry, TS, Remington, B

    Published 2023
    “…An increased radiative opacity of the solar mixture, in particular iron, is a possible explanation for the disagreement in the position of the solar convection zone-radiative zone boundary as measured by helioseismology and predicted by modeling using the most recent photosphere analysis of the elemental composition. …”

    A proposal to measure iron opacity at conditions close to the solar convective zone-radiative zone boundary by Hoarty, D, Morton, J, Jeffery, M, Pattison, L, Wardlow, A, Mangles, S, Rose, S, Iglesias, C, Opachich, K, Heeter, R, Perry, T

    Published 2019
    “…A major problem in stellar modelling is the discrepancy between solar models and helioseismology data in the position of the convective zone-radiative zone boundary in the sun. …”

    Limits on momentum-dependent asymmetric dark matter with CRESST-II. by Angloher, G, Bento, A, Bucci, C, Canonica, L, Defay, X, Erb, A, von Feilitzsch, F, Ferreiro Iachellini, N, Gorla, P, Gütlein, A, Hauff, D, Jochum, J, Kiefer, M, Kluck, H, Kraus, H, Lanfranchi, J, Loebell, J, Münster, A, Pagliarone, C, Petricca, F, Potzel, W, Pröbst, F, Reindl, F, Schäffner, K, Schieck, J, Schönert, S, Seidel, W, Stodolsky, L, Strandhagen, C, Strauss, R, Tanzke, A, Trinh Thi, H, Türkoğlu, C, Uffinger, M, Ulrich, A, Usherov, I, Wawoczny, S, Willers, M, Wüstrich, M, Zöller, A

    Published 2016
    “…One such model based on asymmetric dark matter has been invoked to overcome discrepancies in helioseismology and an indication was found for a particle with preferred mass of 3 GeV=c^2 and cross section of 10^-37cm2 . …”

    A Spectral Solver for Solar Inertial Waves by Jishnu Bhattacharya, Shravan M. Hanasoge

    Published 2023-01-01
    “…The latter allows us to infer properties that are inaccessible to the traditional technique of acoustic wave helioseismology. Thus, a full characterization of these normal modes holds the promise of enabling investigations into solar subsurface dynamics. …”

    A simple model for solar isorotational contours by Balbus, S

    Published 2009
    “…Although the exact solution of the global SCZ problem in principle requires this knowledge, even the simplest models produce striking results in broad agreement with helioseismology data. This includes horizontal (i.e. quasi-spherical) isorotational contours at the poles, axial contours at the equator and approximately radial contours at mid-latitudes. …”
