Abstract:
The Transiting Exoplanet Survey Satellite (TESS) mission has provided
photometric light curves for stars across nearly the entire sky. This
allows for the application of asteroseismology to a pool of potential
solar-like oscillators that is unprecedented in size.
We aim to produce a catalogue of solar-like oscillators observed by
TESS in the 120-second and 20-second cadence modes. The catalogue is
intended to highlight stars oscillating at frequencies above the TESS
30-minute cadence Nyquist frequency with the purpose of encompassing
the main sequence and subgiant evolutionary phases. We aim to provide
estimates for the global asteroseismic parameters νmax and
Δν.
We apply a new probabilistic detection algorithm to the 120-second and
20-second light curves of over 250000 stars. This algorithm flags
targets that show characteristic signatures of solar-like
oscillations. We manually vet the resulting list of targets to confirm
the presence of solar-like oscillations. Using the probability
densities computed by the algorithm, we measure the global
asteroseismic parameters νmax and Δν.
We produce a catalogue of 4177 solar-like oscillators, reporting
Δν and νmax 98% of the total star count. The
asteroseismic data reveals vast coverage of the Hertzsprung-Russell
diagram, populating the red giant branch, the subgiant regime and
extending toward the main sequence.
A crossmatch with external catalogs shows that 25 of the detected
solar-like oscillators are a component of a spectroscopic binary, and
28 are confirmed planet host stars. These results provide the
potential for precise, independent asteroseismic constraints on these
and any additional TESS targets of interest.
Description:
Global asteroseismic parameters Δν and νmax for
solar-like oscillators detected in TESS 120-sec and 20-sec cadence
data. Each star is identified by the TIC ID. The following columns
contain the number of sectors used to make the detection, the responses
in the repeating pattern (RP) and power excess (PE) modules, the
frequency at maximum power (numax), the large frequency spacing (dnu),
the sample the star belongs to and associated flags. Flags identify
whether the star appeared in the Ninth Catalogue of Spectroscopic
Binary Orbits (SB9) or in NASA's Exoplanet Archive.
