Abstract:
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 (νmax, with its median precision
σ=5.39%), large frequency separation (Δν,
σ=6.22%), and seismically derived masses, radii, and surface
gravity values. In this sample, we have detected 2173 new oscillators
and added 4373 new Δν measurements. Our seismic parameters
are consistent with those from Kepler, K2, and previous TESS data. The
median fractional residual in νmax 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 νmax 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.
Description:
We download all available TESS 2 minute cadence light curves spanning
Sectors 1 to 60 from the Mikulski Archive for Space Telescopes (MAST).
TESS launched April 18, 2018; Sector 1 starts on 2018-Jul-25 and
Sector 60 ends on 2023-Jan-18.
