The TESS Stellar Variability Catalog ("TESS-SVC")

The TESS Stellar Variability Catalog (TESS-SVC) describes which stars, among those observed at 2-min cadence in the TESS light curve photometry, show periodic variability over the timescales of 0.01 to 13 days. The TESS-SVC includes a broad range of periodic variable stars (rotation, pulsation, eclipsing binaries, etc.) that were selected based on the photometric periodogram analysis described in Fetherolf et al. 2023. Each star in the TESS-SVC includes the measured period of photometric variability, time and amplitude of the maximum flux, significance of the detected variability signal, properties extracted from the TESS Input Catalog, and a summary figure. Each summary figure shows the full TESS light curve (left panels), Lomb-Scargle periodogram or auto-correlation function (center panels), and the light curve phase-folded on the measured photometric variability period (right panels). The periodogram results provided are extracted from a single sector of TESS PDCSAP photometry, and the method for selecting the specific sector for stars observed in multiple TESS sectors is described in Fetherolf et al. 2023.
