VizieR Online Data Catalog: Classification of A-F spectral type stars (Skarka+, 2022)

We present a classification of A-F spectral type stars brighter than 11 mag that are located in the TESS continuous viewing zone. We found clear signs of variability in 3025 of 5923 studied stars (51%). For 1813 of these 3025 stars, we provide a classification. From the classified stars, 64.5% are pulsating stars of GDOR and DSCT types and their hybrids. We identified a new group of stars showing stable light curves and characteristic frequency spectra pattern (8.5% of the classified stars).

The classification is based on the light-curve shape and Fourier transform of photometric data. We used TESS SPOC and QLP data products. For ech star we give identification in the TIC catalogue, equatorial coordinates, variability type, spectral type based on LAMOST spectra, dominant frequency value, zero epoch (for eclipsing binaries), amplitude of the photometric variations in TESS filter, VSX designation, VSX variability type, information about blending stars, and number of stars that are closer than 5 pixels having brightness difference less than 5mag.
