Accretion through the inner parts of these disks is self regulated by the thermal ionization instability such that long periods (≈1000 .) of low mass flux: (1–10)×10.

Over the past 18 months, we have carried out an extensive survey of fundamental MK spectral standard stars in the near-infrared spanning luminosity classes I–II, III, and IV–V from spectral

We detect a hot molecular core in the emission both of methyl cyanide and of the 110 GHz continuum. We estimate a temperature of 200 K and a mass of 1000 M. for this compact massive region. We also detect

Two competing models describe the mechanism by which the jet sets the molecular cloud in motion: ‘prompt’ entrainment and ‘turbulent’ entrainment. We present a method for distinguishing between the
