Solar Neutrino Flux Fluctuations Caused by Solar Gravity Modes
Yoshiki Hatta, Yuuki Nakano, Sho Sugama +3
We have evaluated fluctuations in neutrino fluxes caused by solar gravity (g) modes based on the analysis of linear adiabatic oscillation of a spherically symmetric star. We find t…
High-order Gravity-mode Period Spacing Patterns of Intermediate-mass () Main-sequence Stars I. Perturbative Analysis
Yoshiki Hatta, Takashi Sekii
Theoretical study of high-order gravity-mode period spacing () pattern is relevant for the better understanding of internal properties of intermediate-mass ($1.5 \, M_\odot <…
Inversion for Inferring Solar Meridional Circulation: The Case with Constraints on Angular Momentum Transport inside the Sun
Yoshiki Hatta, Hideyuki Hotta, Takashi Sekii
We have carried out inversions of travel times as measured by Gizon et al. (2020) to infer the internal profile of the solar meridional circulation (MC). A linear inverse problem h…
Detecting active latitudes of Sun-like stars using asteroseismic a-coefficients
Othman Benomar, Masao Takata, Michael Bazot +3
We introduce a framework to measure the asphericity of Sun-like stars using , and coefficients, and constrain their latitudes of magnetic activity. Systematic erro…
Bayesian rotation inversion of KIC 11145123
Yoshiki Hatta, Takashi Sekii, Othman Benomar +1
A scheme of Bayesian rotation inversion, which allows us to compute the probability of a model of a stellar rotational profile, is developed. The validation of the scheme with simp…
The two-dimensional internal rotation of KIC11145123
Yoshiki Hatta, Takashi Sekii, Masao Takata +1
The two-dimensional internal rotation of KIC11145123 has been inferred via asteroseismology. Based on the Optimally Localized Averaging method and a simple three-zone modeling of t…
