Position of DESI-HVS1 on the (g − i)₀ versus M_r diagram compared with theoretical stellar isochrones. The black point with error bars indicates the measured photometric location of DESI-HVS1. The background curves show PARSEC isochrones spanning ages from 5 to 15 Gyr in 1 Gyr increments, arranged from left to right in order of increasing age. The color scale denotes stellar mass, as illustrated by the color bar on the right. All isochrones are computed at fixed [M/H] = −1.26, converted from [Fe/H] = −1.64 and [α/Fe] = + 0.50. The inset panel provides a magnified view for clarity.
