Abstract:
We aim to detect and characterise solar-like oscillations in
bright naked-eye (V<6) main-sequence and subgiant stars observed by
the Transiting Exoplanet Survey Satellite (TESS). In doing so, we seek
to expand the current benchmark sample of oscillators, provide
accurate global asteroseismic parameters for these bright targets, and
assess their potential for future detailed investigations -- including
missions such as the Habitable Worlds Observatory (HWO) and PLAnetary
Transits and Oscillations of stars (PLATO).
Our sample of bright stars was selected from the Hipparcos/Tycho
catalogues. We analysed TESS photometry from both 120-s and 20-s
cadences using the standard TESS Science Processing Operations Center
(SPOC) light curves and custom apertures extracted from target pixel
files. After applying a filtering of the light curves, we extracted
global asteroseismic parameters (νmax and Δν) using the
pySYD pipeline. Results were cross-validated with independent
pipelines and compared to predictions from the Asteroseismic Target
List (ATL), while noise properties were evaluated to quantify
improvements from a 20-s observing cadence.
We detect solar-like oscillations in a total of 196 stars -- including
128 new detections -- with extracted νmax and Δν values
showing strong conformity to expected scaling relations. This
corresponds to an increase by more than an order of magnitude in the
number of main-sequence stars with detection of solar-like
oscillations from TESS. Importantly, our sample of newly detected
solar-like oscillators includes nearly 40% of the prime targets for
HWO, paving the way for a systematic determination of asteroseismic
ages that will be important for the possible interpretation of
atmospheric biosignatures. Our analysis confirms that 20-s cadence
data yields lower high-frequency noise levels compared to 120-s
data. Moreover, the precise stellar parameters obtained through
asteroseismology establish these bright stars as benchmarks for
seismic investigations and provide useful constraints for refining
stellar evolution models and for complementary analyses in
interferometry, spectroscopy, and exoplanet characterisation.
Description:
With the TLS, we have provided detections of asteroseismic signals for
a total of 196 MS/SG stars, visible to the naked eye (V≤6). Of these,
to the best of our knowledge, 128 are new detections. Given the
brightness of this sample compared to most asteroseismic stars from
Kepler, it is possible to obtain a high-quality characterisation of
the stars from ground-based efforts, and many of the stars already
have extensive literature from decades of scrutiny. Our goal with this
analysis has been to report on the asteroseismic detections, to
encourage continued observations from TESS, and to highlight the many
potential uses of the sample in future in-depth analyses.
