Toomre diagram showing the Galactic space velocities of TIC 183374187 relative to the local standard of rest (LSR). The star’s velocity components (ULSR,VLSR, andWLSR) were computed using Gaia DR3 astrometry and radial velocity. The dashed curves indicate loci of constant total space velocity. Gray points indicate kinematics of the other targets in my sample with a Gaia DR3 radial velocity measurements. The position of TIC 183374187 indicates kinematics consistent with membership in the Galactic thick disk. This interpretation is supported further by spectral chemical abundance measurements.
