The relationship between photometric and spectroscopic oscillation amplitudes from 3D stellar atmosphere simulations

no code implementations3 Feb 2021 Yixiao Zhou, Thomas Nordlander, Luca Casagrande, Meridith Joyce, Yaguang Li, Anish M. Amarsi, Henrique Reggiani, Martin Asplund

For the Sun, we predict theoretical ratios of 21. 0 and 23. 7 ppm/[m/s] from BiSON and SONG respectively, in good agreement with observations 19. 1 and 21. 6 ppm/[m/s].

Mode Angular Degree Identification in Subgiant Stars with Convolutional Neural Networks based on Power Spectrum

no code implementations24 Dec 2020 Minghao Du, Shaolan Bi, Xianfei Zhang, Yaguang Li, Tanda Li, Ruijie Shi

Identifying the angular degrees $l$ of oscillation modes is essential for asteroseismology and depends on visual tagging before fitting power spectra in a so-called peakbagging analysis.
