Astrophysical masers

The formation of high-mass stars is a complex process, being far less understood than it is for low-mass stars. Gas accretion, molecular outflows and shock waves are among the first phenomena indicating star-forming activity that can be studied by mean of radio molecular lines. In the environment of massive stars the radiation of molecules is sometimes amplified by the maser mechanisms and it can be easily detectable with a medium size radio telescope. Furthermore, the maser radiation is observed from deeply embedded protostars and distance galaxies without being distorted by the interstellar medium. Studies with the use of the 32m telescope concerns the search for high-mass stars in the very early stages of evolution.
