A large contracting protoplanet will pass through a brief line_5: period of high luminosity. It may be possible, under ideal conditions, to line_6: detect a more massive protoplanet around nearby, solar-type T Tauri stars. The line_7: HST has the capability to perform superior quality, direct imaging at a high line_8: spectral resolution in the near-infrared needed to detect these very warm, line_9: collapsing protoplanets. ! ! end of abstract general_form_proposers: lname: LARSON fname: ANA title: P.I. mi: M. inst: UNAFFILIATED (AMATEUR) country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Observations are with the WF/PC, image mode.
