![Stellar [α/Fe] versus [Fe/H] for planet-hosting stars analyzed in this work (orange circles). The heat map represents the density of stars from APOGEE DR17 in the [α/M] vs [Fe/H] parameter space for reference. The black line approximately divides the thin and thick disk populations (below and above the line, respectively) as defined by D. H. Weinberg et al. 2019. The red points represent stars from the SPOCS sample from J. M. Brewer et al. (2016). The Sun is over-plotted for reference. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/05/A-Uniform-Determination.png?resize=1200%2C715&ssl=1)
We present a uniform spectroscopic characterization of 625 F, G, and K stars hosting 859 confirmed exoplanets using high-resolution archival optical spectra from the Tillinghast Reflector Echelle Spectrograph (TRES).

Interior Convection Regime, Host Star Luminosity, And Predicted Atmospheric CO2 Abundance In Terrestrial Exoplanets
Terrestrial planets in the Habitable Zone of Sun-like stars are priority targets for detection and observation by the next generation of powerful space telescopes.
