The Science Case for ALMA Band 2 and Band 2+3 [PDF]

, 2016
We discuss the science drivers for ALMA Band 2 which spans the frequency range from 67 to 90 GHz. The key science in this frequency range are the study of the deuterated molecules in cold, dense, quiescent gas and the study of redshifted emission from ...

The Cosmochemistry of Protostellar Matter [PDF]

, 1990
The different processes that can affect the chemical composition of matter as it evolves from quiescent molecular clouds into protostellar regions is discussed. Millimeter observations of molecules at high angular resolution in cold, dark clouds such

Silicon monoxide masers and the magnetic field of R Cassiopeiae

, 2012
Silicon monoxide maser emission has been detected in many evolved stars in circumstellar envelopes in different vibrationally-excited rotational transitions. It is considered a good tracer to study the dynamics in a region close to the photosphere of the star.

Non-equilibrium processes in interstellar molecules [PDF]

The types of nonequilibrium emission and absorption by interstellar molecules are summarized. The observed brightness emission temperatures of compact OH and H2O sources are discussed using the concept of maser amplification.
