| The TMT will have sufficient point-source sensitivity to permit direct detection of gas giants, achieving a 'tipping' point in sensitivity to achieve this exciting goal. In a gas is in thermal equilibrium with irradiation by the central star, MICHI will be capable of detecting such giants at a distance of a few AU from nearby (~10 pc) early type (AFG type) stars. If a young (~1 Gyr) planet's temperature is determined by its own internal heating (Burrows et al. 2004), detectability is easier. MICHI observations of gas giants holds the promise of the characterization ~5 times closer to the central star than MIR space-based facilities due to the superior spatial resolution. | The TMT will have sufficient point-source sensitivity to permit direct detection of gas giants, achieving a 'tipping' point in sensitivity to achieve this exciting goal.
