Summary

Simulated long-baseline photometry put one-Earth-radius habitable-zone candidates near 40-percent recovery around the field's M dwarfs.

An end-to-end pipeline study forecasts about four habitable-zone Earths and seven super-Earths among 16,929 M dwarfs in PLATO's LOPS2 field. At the adopted detection floor, completeness was 54 percent and the false-alarm rate 6 percent; the yield remains a simulation-based forecast, not detected planets.

Why it matters

Simulated long-baseline photometry put one-Earth-radius habitable-zone candidates near 40-percent recovery around the field's M dwarfs.

Limits and context

  • At the adopted detection floor, completeness was 54 percent and the false-alarm rate 6 percent; the yield remains a simulation-based forecast, not detected planets.
