| 英文摘要 | The TESS space mission has generated an extensive collection of light curves, providing a valuable opportunity to search for solar-like oscillations. 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. The nu max and Delta nu of oscillators were determined using the fitting and autocorrelation, and the reliability of the Delta nu measurements was further evaluated using the Fourier spectrum of the autocorrelation function. Based on this assessment, 4775 oscillators were classified as having reliable Delta nu, including 1920 that have Delta nu measured for the first time. |
