... An analysis on new observational data taken with the MPFS and SCORPIO spectrographs indicates that we are dealing with the "galactic wind": the gas is blown above the galactic plane with the characteristic velocity of about 130km/s. The gas outflow is caused by a combined action of winds from the supernovae and young massive stars located in the galaxy's circumnuclear region. ... The most probable hypothesis is that the accretion of intergalactic gas clouds is feeding their star formation. ...

... This example explores the evolution of the sun. ... Given that the mass of proton is 1.00870 atomic mass units and the mass of a helium nucleus is 4.0026 atomic mass units, estimate the sun's average rate of energy production by nuclear reactions (in solar luminosities) over its lifetime. Take the age of the sun as 4.5 в 109 yr. Does nuclear energy production seem to successfully account for the energy output of the sun? (b) Comment on the changes in the abundance profiles as the sun ages. ...

... 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. ...
