abstract = {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) during its Cycle 1 observations. We identify 12 new roAp stars. Amongst
these stars we discover the roAp star with the longest pulsation period, another with the shortest rotation period, and six with
multiperiodic variability. In addition to these new roAp stars, we present an analysis of 44 known roAp stars observed by TESS
during Cycle 1, providing the first high-precision and homogeneous sample of a significant fraction of the known roAp stars.
The TESS observations have shown that almost 60 per cent (33) of our sample of stars are multiperiodic, providing excellent
cases to test models of roAp pulsations, and from which the most rewarding asteroseismic results can be gleaned. We report
four cases of the occurrence of rotationally split frequency multiplets that imply different mode geometries for the same degree
modes in the same star. This provides a conundrum in applying the oblique pulsator model to the roAp stars. Finally, we report
the discovery of non-linear mode interactions in α Cir (TIC 402546736, HD128898) around the harmonic of the principal mode
– this is only the second case of such a phenomenon.},
