KIC 12602250: A low-amplitude Double-mode Scuti star with Amplitude Modulation
Chenlong Lv, Ali Esamdin, Xiangyun Zeng +3
We propose for the first time that KIC 12602250 is a low-amplitude radial double-mode Scuti star with amplitude modulation. The detailed frequency analysis is given for the lig…
Study of rotational splittings in ~Scuti stars using pattern finding techniques
A. Ramón-Ballesta, A. García Hernández, J. C. Suárez +3
Detecting and understanding rotation in stellar interiors is nowadays one of the unsolved problems in stellar physics. Asteroseismology has been able to provide insights on rotatio…
TESS Cycle 1 observations of roAp stars with 2-min cadence data
D. L. Holdsworth, M. S. Cunha, D. W. Kurtz +41
We present the results of a systematic search for new rapidly oscillating Ap (roAp) stars using the 2-min cadence data collected by the Transiting Exoplanet Survey Satellite (TESS)…
Searching for signatures of chaos in gamma-ray light curves of selected Fermi-LAT blazars
O. Ostapenko, M. Tarnopolski, N. Żywucka +1
Blazar variability appears to be stochastic in nature. However, a possibility of low-dimensional chaos was considered in the past, but with no unambiguous detection so far. If pres…
TESS observations of Cepheid stars: first light results
E. Plachy, A. Pál, A. Bódi +33
We present the first analysis of Cepheid stars observed by the TESS space mission in Sectors 1 to 5. Our sample consists of 25 pulsators: ten fundamental mode, three overtone and t…
Self-consistent method to extract non-linearities from pulsating stars light curves I. Combination frequencies
M. Lares-Martiz, R. Garrido, J. Pascual-Granado
Combination frequencies are not solutions of the perturbed stellar structure equations. In dense power spectra from a light curve of a given multi-periodic pulsating star, they can…
