1. 1. Observations and analysis of water in molecular outflows and shocks

   Författare :Per Bjerkeli; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interstellar medium; molecules; jets and outflows; pre-main-sequence; stars; supernova remnants;

   Sammanfattning : This thesis describes observations and analysis of molecular outflows from young stellar objects. The observations using the Odin satellite are described in Paper I, where a non-LTE radiative transfer code has been used to estimate the ortho-water abundance in seven molecular outflows and one super-nova remnant.

   Sammanfattning : This thesis describes observations and analyses of water in molecular outflows from young stellar objects. The abundance of this molecule (with respect to molecular hy- drogen) is deduced from observations carried out with primarily the Odin and Herschel telescopes. LÄS MER
