Guangrong Daiof about 0.03 pc, as expected for the infalling gas around a 1 M. star. High-resolution far-infrared observations of star forming regions in Taurus (L1551 IRS 5) and Orion (NGC 2071) are consistent with density gradients with n(r) ∞ r., again consistent with infalling gas; in addition, direct compar

Guangrong Daid nearby stars. The astrometric study of a parent star of a planetary system will lead to an accurate determination of its distance. The distance is inversely proportional to the magnitude of the annual parallactic motion. The same study yields the major characteristics of the individual bodies with
