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

Minghao Du, Shaolan Bi, Xianfei Zhang +3

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

The Evolution of Rotation and Magnetic Activity in 94 Aqr Aa from Asteroseismology with TESS

Travis S. Metcalfe, Jennifer L. van Saders, Sarbani Basu +29

Most previous efforts to calibrate how rotation and magnetic activity depend on stellar age and mass have relied on observations of clusters, where isochrones from stellar evolutio…

Asteroseismology of 36 Kepler subgiants -- II: Determining ages from detailed modelling

Tanda Li, Timothy R. Bedding, Jørgen Christensen-Dalsgaard +3

Detailed modelling of stellar oscillations is able to give precise estimates for stellar ages, but the inferred results typically depend on the adopted model parameters used for th…

Asteroseismology of 36 \emph{Kepler} subgiants -- I. Oscillation frequencies, linewidths and amplitudes

Yaguang Li, Timothy R. Bedding, Tanda Li +4

The presence of mixed modes makes subgiants excellent targets for asteroseismology, providing a probe for the internal structure of stars. Here we study 36 \emph{Kepler} subgiants…

Solar-type Stars Observed by LAMOST and Kepler

Jinghua Zhang, Alexander I. Shapiro, Shaolan Bi +8

Obtaining measurements of chromospheric and photometric activity of stars with near-solar fundamental parameters and rotation periods is important for a better understanding of sol…

TESS Asteroseismic Analysis of the Known Exoplanet Host Star HD 222076

Chen Jiang, Timothy R. Bedding, Keivan G. Stassun +24

The Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission aiming to search for exoplanets that transit bright stars. The high-quality photometric data of TESS a…
