TOI-1227 b is one of the youngest transiting exoplanets discovered (as of September 2022), alongside K2-33b and HIP 67522 b.
Evolutionary models suggest that TOI-1227 b will eventually evolve into a sub-Neptune within the next billion years.
[1] Radial velocity follow-up to determine the mass of TOI-1227 b is not possible in the optical, but might be possible in the near-infrared.
The host star is relative faint for a TOI with a visual magnitude of about 17.
[2][c] The host star shows Lithium in its atmosphere, which should be depleted within 10-200 million years for M-dwarfs.
