Limitations of TESS in characterizing the first habitable zone Earth-sized planet

Recently, the TOI-700 System was characterized as the first habitable-zone Earth-sized planet using Transiting Exoplanet Survey Satellite (TESS). Ground-based follow-up combined with diagnostic vetting and validation tests enables this system to rule out common astrophysical false-positive scenarios and validate the planetary data.  However, TESS systems are restricted by a Nyquist limit that can interfere with internal structure data, especially at different oscillation modes. Another key limitation is the necessity of an ultra-stable light source for standardization purposes. Although several studies have shown promise, reliable data has yet to be validated.
