  "abstract": "Properties of solar twins reported by Lehmann et al. (2023) at kiloparsec distances from the local standard of rest (LSR) are compared to solar twins within 100 pc of the Sun. These have velocity distributions closely similar to those of the nearby twins in addition to closely matching $T_{\\rm eff}$, $\\log{(g)}$ and $[Fe/H]$. The new twins are at slightly higher galactic latitudes, and are somewhat closer to the Galactic center. Additionally, they may be significantly older than nearby solar twins.",
