Machine learning for understanding pulsating stars I: the non-linear phenomenon in δ Scuti stars
J. R. Rodon, J. Pascual-Granado, M. Lares-Martiz +2
Scuti stars are pulsating variable stars that exhibit both radial and non-radial pulsations, making them key objects for understanding stellar evolution and internal structures…
Evaluating the Limits of Rotation Period Recovery through Gyrochronology Criteria
Mariel Lares-Martiz, Terry D. Oswalt, Derek L. Buzasi +3
Contamination from nearby sources often compromises stellar rotation periods derived from photometric light curves, particularly in data with large pixel scales such as TESS. This…
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…
The PL diagram for Sct stars: back in business as distance estimators
A. García Hernández, J. Pascual-Granado, M. Lares-Martiz +4
In this work, we focus on the period-luminosity relation (PLR) of Sct stars, in which mode excitation and selection mechanisms are still poorly constrained, and whose structure…
ET White Paper: To Find the First Earth 2.0
Jian Ge, Hui Zhang, Weicheng Zang +163
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time,…
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)…
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…
Rotation and pulsation in Ap stars: first light results from TESS sectors 1 and 2
M. S. Cunha, V. Antoci, D. L. Holdsworth +36
We present the first results from the Transiting Exoplanet Survey Satellite (TESS) on the rotational and pulsational variability of magnetic chemically peculiar A-type stars. We an…
Physical insights on fractal analysis applied to light curves Scuti stars
S. de Franciscis, J. Pascual-Granado, J. C. Suárez +4
Fractal fingerprints have been found recently in the light curves of several δ Scuti stars observed by CoRoT satellite. This sole fact might pose a problem for the detection of pul…
Impact of gaps in the asteroseismic characterization of pulsating stars. I. On the efficiency of pre-whitening
J. Pascual-Granado, J. C. Suárez, R. Garrido +4
It is known that the observed distribution of frequencies in CoRoT and Kepler δ Scuti stars has no parallelism with any theoretical model. Pre-whitening is a widespread technique i…
