A complex network approach to TESS light curves of Sct stars
E. Ziaali, S. de Franciscis, J. Pascual-Granado +4
By using the horizontal visibility algorithm, the TESS light curves of 69 delta Sct stars are mapped to undirected horizontal visibility graphs (HVGs), where the graph nodes repres…

Signature of high-amplitude pulsations in seven Delta Sct stars via TESS observations
Fatemeh Vasigh, Elham Ziaali, Hossein Safari
The regular behavior of the pulsations of high-amplitude Delta Sct (HADS) stars gives a greater chance to investigate the interiors of stars. We analyzed seven HADS stars showing p…

TESS Cycle 2 observations of roAp stars with 2-min cadence data
D. L. Holdsworth, M. S. Cunha, M. Lares-Martiz +46
We present the results of a systematic search of the Transiting Exoplanet Survey Satellite (TESS) 2-min cadence data for new rapidly oscillating Ap (roAp) stars observed during the…
