Detection of Solar-like Oscillations in Sub-giant 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 8,651 solar-like oscillators, including frequency at maximum power (ν_ max, with its median precision, σ=5.39%), large frequency separation (Δν, σ=6.22%), seismically derived masses, radii, and surface gravity. In this sample, we have detected 2,173 new oscillators and added 4,373 new Δν measurements. Our seismic parameters are consistent with those from Kepler, K2, and previous TESS data. The median fractional residual in ν_ max is 1.63% with a scatter of 14.75%, and in Δν it is 0.11% with a scatter of 10.76%. We have detected 476 solar-like oscillators with ν_ max exceeding the Nyquist frequency of Kepler long-cadence data during the evolutionary phases of sub-giant and the base of the red-giant branch, which provide a valuable resource for understanding angular momentum transport.
