KMT-2025-BLG-2093: Free-Floating Planet Candidate Near the Shore of the Einstein Desert
Abstract
We analyze KMT-2025-BLG-2093, with angular Einstein radius θ E=13.1 2.8\,μ as, which makes it the second isolated microlens that lies in the ``Einstein Desert'' (9\,μ as<θ E<25\,μ as) between free-floating planets (FFPs) on one side and brown dwarfs and stars on the other. We discuss how its characteristics may give clues to future exploration of FFPs, especially in the era of satellite missions that have a major FFP focus, including Earth 2.0 and Roman.
