Habitable Worlds Observatory target stars in terms of their luminosity and distance, with values adopted from the tables of Mamajek & Stapelfeldt (2024). Filled markers indicate stars with detected oscillations, with the colour and shape indicating the HWO tier (see legend). Stars with unfilled black thick-edged markers were considered for analysis, while black thin-edged ones did not conform to the selection criteria for our sample. Stars with red thick-edged markers were considered but did not have data available before S77, as considered in this analysis (but will later in Cycle 7), while red thin-edged ones are not scheduled for observations with TESS. The legend showing the different tiers gives, in parentheses, the number of detections out of the total number of stars in the tier, and lastly, the number of stars from each tier that we analysed.
