Detection of Solar-like Oscillations in Subgiant and Red Giant Stars Using 2 Minute Cadence TESS Data

Based on all 2 minute cadence TESS light curves from Sector 1 to 60, we provide a catalog of 8651 solar-like oscillators, including frequency at maximum power ( nu max , with its median precision sigma = 5.39%), large frequency separation (Delta nu, sigma = 6.22%), and seismically derived masses, radii, and surface gravity values. In this sample, we have detected 2173 new oscillators and added 4373 new Delta nu measurements. Our seismic parameters are consistent with those from Kepler, K2, and previous TESS data. The median fractional residual in nu max is 1.63%, with a scatter of 14.75%, and in Delta nu it is 0.11%, with a scatter of 10.76%. We have detected 476 solar-like oscillators with nu max exceeding the Nyquist frequency of Kepler long-cadence data during the evolutionary phases of subgiants and the base of the red giant branch, which provide a valuable resource for understanding angular momentum transport.
