## TL;DR

This paper presents a curated list of bright, solar-like stars for asteroseismology with TESS, using Gaia and Hipparcos data to optimize target selection and predict detection yields, facilitating future stellar studies.

## Contribution

The paper introduces the ATL, a target list for TESS asteroseismology, with a detailed methodology and publicly available code for reproducibility and comparison with stellar population models.

## Key findings

- Target list includes bright, cool main-sequence and subgiant stars.
- Predicted detection probabilities based on TESS's photometric performance.
- Publicly available code enables reproducibility and comparison with models.

## Abstract

We present the target list of solar-type stars to be observed in short-cadence (2-min) for asteroseismology by the NASA Transiting Exoplanet Survey Satellite (TESS) during its 2-year nominal survey mission. The solar-like Asteroseismic Target List (ATL) is comprised of bright, cool main-sequence and subgiant stars and forms part of the larger target list of the TESS Asteroseismic Science Consortium (TASC). The ATL uses Gaia DR2 and the Extended Hipparcos Compilation (XHIP) to derive fundamental stellar properties, calculate detection probabilities and produce a rank-ordered target list. We provide a detailed description of how the ATL was produced and calculate expected yields for solar-like oscillators based on the nominal photometric performance by TESS. We also provide publicly available source code which can be used to reproduce the ATL, thereby enabling comparisons of asteroseismic results from TESS with predictions from synthetic stellar populations.
