Probability of detecting at least one magma ocean planet in nearby young stellar associations (Table 1) for observation times of 5 h (panel A) and 50 h (panel B). The colors and shapes refer to telescope filters and atmospheric emissivities, respectively. The prime stellar target for the detection of magma oceans is the β Pictoris association (37 pc, 23 Myr), followed by Columba (50 pc, 42 Myr), TW Hydrae (53 pc, 10 Myr), and Tucana-Horologium (48 pc, 45 Myr). Due to the low probability of giant impacts at their respective ages (Fig. 1B), no data points are shown for stars located inside the AB Doradus association (20 pc, 150 Myr). ELT 11.6 μm is not able to detect any magma ocean planets.
