X-RAY EMISSION FROM THE YOUNGEST STARS
ABSTRACT
X-ray emission from protostars has recently been detected by both ROSAT and ASCA. Although such emission is common from the slightly older T Tauri star class (interpreted as enhanced solar type magnetic activity), emission from the much younger and cooler protostellar phase is not well understood. We seek to better understand the nature of this emission which has important implications for star formation regulation and the ionization of circumstellar disks and outflows. Three fields are proposed containing the near-by, well-separated, luminous protostars, L723, RNO 43 and RNO 91. ASCA's unique ability to observe protostars through heavy extinction is necessary for this project.
