On the characterization of GJ 504: a magnetically active planet-host star observed by the Transiting Exoplanet Survey Satellite (TESS)

Maria Pia Di Mauro, Raffaele Reda, Savita Mathur +10

We present the results of the analysis of the photometric data collected in long and short-cadence mode by the Transiting Exoplanet Survey Satellite (TESS) for GJ 504, a well studi…

Solar-like oscillations and ellipsoidal variations in TESS observations of the binary 12 Boötis

Warrick H. Ball, Andrea Miglio, William J. Chaplin +14

Binary stars in which oscillations can be studied in either or both components can provide powerful constraints on our understanding of stellar physics. The bright binary 12 Boötis…

Meta-analysis of photometric and asteroseismic measurements of stellar rotation periods: the Lomb-Scargle periodogram, autocorrelation function, wavelet and rotational splitting analysis for 92 Kepler asteroseismic targets

Yuting Lu, Othman Benomar, Shoya Kamiaka +1

We perform photometric (the Lomb-Scargle periodogram, autocorrelation, and wavelet) and asteroseismic analyses of 92 Kepler solar-like main-sequence stars to understand the reliabi…

Analytic model for photometric variation due to starspots on a differentially rotating star

Yasushi Suto, Shin Sasaki, Yuta Nakagawa +1

We present an analytic model of the lightcurve variation for stars with non-evolving starspots on a differentially rotating surface. The Fourier coefficients of the harmonics of th…

Measuring frequency and period separations in red-giant stars using machine learning

Siddharth Dhanpal, Othman Benomar, Shravan Hanasoge +4

Asteroseismology is used to infer the interior physics of stars. The \textit{Kepler} and TESS space missions have provided a vast data set of red-giant light curves, which may be u…
