Imaging the Solar Tachocline by Time-Distance Helioseismology

, 2009
The solar tachocline at the bottom of the convection zone is an important region for the dynamics of the Sun and the solar dynamo. In this region, the sound speed inferred by global helioseismology exhibits a bump of approximately 0.4% relative to the ...

Planetary influence on the young Sun's evolution: the solar neutrino probe

, 2013
Recent observations of solar twin stars with planetary systems like the Sun, have uncovered that these present a peculiar surface chemical composition. This is believed to be related to the formation of earth-like planets.

The spectroscopy of solar sterile neutrinos

European Physical Journal C: Particles and Fields, 2018
We predict the sterile neutrino spectrum of some of the key solar nuclear reactions and discuss the possibility of these being observed by the next generation of solar neutrino experiments.

Determining the initial helium abundance of the Sun

, 2010
We determine the dependence of the initial helium abundance and the present-day helium abundance in the convective envelope of solar models ($\yim$ and $\ysm$ respectively) on the parameters that are used to construct the models.

Characterizing the Observational Properties of the Sun’s High-latitude m = 1 Inertial Mode

The Astrophysical Journal
Low- m inertial modes have been recently discovered in the Sun’s high-latitude regions. In this study, we characterize the observational properties of the m = 1 mode by analyzing time–distance subsurface flow maps.

The Sun’s Dark Core: Helioseismic and Neutrino Flux Constraints on a Compact Solar Center

The Astrophysical Journal
As dark matter appears to comprise most of the Galactic mass, some of it may accumulate in the cores of stars, thereby making the Sun a laboratory for constraining various dark matter theories.

Helioseismology: a fantastic tool to probe the interior of the Sun

, 2012
Helioseismology, the study of global solar oscillations, has proved to be an extremely powerful tool for the investigation of the internal structure and dynamics of the Sun.

The Shape of the Solar Tachocline

The Astrophysical Journal
Early helioseismic results have shown that the tachocline has a prolate shape. However, the models used in those studies constrained the tachocline to be either prolate or oblate.
