Southern short-period pulsating hot-subdwarf stars

We describe the TESS data used and the details of the search method. For many of the targets, we use unpublished spectroscopic observations to classify the objects.

From the TESS photometry, we clearly identify 43 short-period hot-subdwarf pulsators, including 32 sdB stars, eight sdOB stars, two sdO stars, and, significantly, one He-sdOB star, which is the first of this kind to show short-period pulsations. Eight stars show signals at both low and high frequencies, and are therefore "hybrid" pulsators.We report the list of prewhitened frequencies and we show the amplitude spectra calculated from the TESS data.
