Solar-like oscillators catalogue

Listed in IVOA Registry (Virtual Observatory)

The Transiting Exoplanet Survey Satellite (TESS) mission has provided photometric light curves for stars across nearly the entire sky.

Description

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 {nu}_max_ and {Delta}{nu}. 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 {nu}_max_ and {Delta}{nu}.

We produce a catalogue of 4177 solar-like oscillators, reporting {Delta}{nu} and {nu}_max_ 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.
