... We have used a coupled dynamical and chemical model to examine the chemical changes caused by the passage of a density wave propagating into the protostellar cloud. ... The chemical coupling between gas and dust causes locally increased number densities of active ra dicals, such as C, N, O, NH, and OH, and hydrogen saturated molecules CH 4 , NH 3 and H 2 O. We show that chemical evolution in the post-wave gas can account for the observed abundance of water and NH 3 observed in interstellar clouds. ...

Theory of filtering and time series processing L. Zotov Laboratory work ?4 Purpose: Studying wavelet analysis of signals. We use Matlab software (look into the Lab N1). 1) Download program for the lab from http://lnfm1.sai.msu.ru/grav/english/lecture/filtering/ Study the wavelet transform of the signal with changing frequency content. Use different types of wavelets. Change the signal. Include the impulse, study the triangle of its influence on the wavelet coefficients.

EVOLUTION OF RADIO NOISE STORMS AT COMPRESSED DYNAMIC SPERTRA . ... An analysis of large-scale variations of noise storm intensity and frequency spectra has been carried out basing on IZMIRAN dynamic radio spectra compressed in time. It is shown that various enhancements and weakening of noise storms as well as changes of their frequency spectrum appear to be caused by effects of coronal mass ejections on sources of the emission or/and electron acceleration in the corona. ...
