On the Abundance Gradients of Organic Molecules along the Tmc-1 Ridge
Gradients in molecular abundances along the TMC-1 ridge have been observed by several authors, most recently in a comprehensive study by Pratap et al. These can be explained by there being a di†erence in density, C/O ratio, or chemical evolutionary state along the ridge. The presence at the carbonrich ““ cyanopolyyne peak ÏÏ (CP) of speciÐc oxygen-bearing molecules, believed to be products of g...
متن کاملCH 3 OH abundance in low mass protostars
We present observations of methanol lines in a sample of Class 0 low mass protostars. Using a 1-D radiative transfer model, we derive the abundances in the envelopes. In two sources of the sample, the observations can only be reproduced by the model if the methanol abundance is enhanced by about two order of magnitude in the inner hot region of the envelope. Two other sources show similar jumps...

During a brief visit to Bangladesh, in December 2005, I spotted a recent edition of the national encyclopaedia (the Banglapedia), in the showcase of a professor of history at Rajshahi University. I eagerly searched for a reference to the Garos, among who I had carried out research between 1993 and 2000, and to my satisfaction, discovered four whole pages devoted to their history, culture, relig...
