TABLE 4.6 Panel’s Conclusions Regarding Detection of Habitable Planets Around M Dwarfs

Technique

Requirements

Radial velocity (RV)

1 m sec−1, on M dwarfs, requiring red-near-IR spectroscopy and new wavelength calibration methods (gas cells, laser combs)

Substantial expansion of currently available observing time on 4- to 10-m-class telescopes for M dwarf survey

Precision photometry/spectroscopy

Transit survey (precision 10−4-105 of host-stellar signal) for 104 closest M dwarfs

Characterization of activity of M dwarfs within 50 pc

JWST primary/secondary transit spectroscopy, 10−4-10−5 of host-stellar signal
