Color–magnitude diagram showing the targets in the ExEP target list for HWO. The gray points represent a sample of stars within 100 pc taken from Gaia DR3. The cyan points indicate the locations of the E. Mamajek & K. Stapelfeldt (2024) targets that are in Gaia and have not been observed with speckle imaging. Orange squares highlight 80 ExEP list targets that have ‘Alopeke, Zorro, or NESSI observations. Red stars show the 27 targets that have been identified as members of stellar multiples by this work. The top axis provides approximate G − G_RP values for F0V, G0V, K0V, and M0V stars.
