Solar-like oscillations using TESS 2

Numerous studies have utilized TESS observations to search for solar-like oscillations and achieved excellent results. However, the number of oscillators found by the previous works may be incomplete and significantly below the predicted count.

Therefore, we employed a novel method to search for solar-like oscillations. In this work, we utilized TESS 2-minute cadence data to identify solar-like oscillators in the southern ecliptic hemisphere, detecting the presence of oscillations by identifying an excess power hump in the spectrum and combining visual inspection. As a result, we identified 10,548 stars exhibiting solar-like oscillations including 2972 that had not been reported in previous studies.
