Asteroseismology and interferometry
Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies of solar-like pulsators, have boosted the impact of this field of research within Astrophysics and have led to a significant increase in the size of the research community. In the present paper we start by reviewing t...

متن کاملAsteroseismology and interferometry of the red giant star Ophiuchi
The GIII red giant star Oph has been found to exhibit several modes of oscillation by the MOST mission. We interpret the observed frequencies of oscillation in terms of theoretical radial p-mode frequencies of stellar models. Evolutionary models of this star, in both shell H-burning and core He-burning phases of evolution, are constructed using as constraints a combination of measurements from ...
متن کاملThe radius and mass of the subgiant star β Hyi from interferometry and asteroseismology
We have used the Sydney University Stellar Interferometer (SUSI) to measure the angular diameter of β Hydri. This star is a nearby G2 subgiant whose mean density was recently measured with high precision using asteroseismology. We determine the radius and effective temperature of the star to be 1.814± 0.017 R⊙ (0.9%) and 5872± 44 K (0.7%) respectively. By combining this value with the mean dens...
متن کاملThe Complementary Roles of Interferometry and Asteroseismology in Determining the Mass of Solar-type Stars
How important is an independent diameter measurement for the determination of stellar parameters of solar-type stars? When coupled with seismic observables, how well can we determine the stellar mass? If we can determine the radius of the star to between 1% and 4%, how does this affect the theoretical uncertainties? Interferometry can provide an independent radius determination, and it has been...
