摘要: We report VLA detections at 1.3, 2, and 3.6 cm of the Egg Nebula, RAFGL 2688. resolve source find an inner 9'' diameter core that is produced by ~0.01 M⊙ dust. It seems Nebula experienced a major mass ejection, losing ~1 during past ≤1200 yr. The centimeter-wavelength emission extended position angle 53°, while famous jets lobes in lie along 15°. multiple symmetries may occur because rotation axis mass-losing star not perpendicular to orbital plane putative close binary. Between 350 μm, dust opacity appears vary as ν0.6, which can be explained if there are some grains with sizes least large 0.5 cm.
