The gr8stars collaboration has compiled a large, precise catalog of bright FGKM dwarf stars with homogeneously derived stellar parameters from high-resolution spectra. This work provides crucial data for stellar and exoplanetary research, offering both spectroscopic and photometric measurements accessible through an online database.

Why it matters: A uniform, accurate stellar parameter catalog supports reliable studies of stars and their exoplanets.

The big picture: Combining archival and new spectra, the study covers 5645 stars with 1716 having detailed spectroscopic analysis.

Stunning stat: Median uncertainties achieved are just 106K in temperature, 0.08 dex in gravity, and 0.03 dex in metallicity.

Quick takeaway: The dataset includes kinematic classifications and is publicly available via an interactive online platform.
