The compression of the cloud of gas in star forming . ... These data have allowed us to create the dynamic model of the cloud of gas, around this object. ... The results on H2CO absorption lines (figure 1) have shown, that the central part of the cloud represents a clumped envelope of diameter 9 pc with radial velocity 20 km/s. The relation of radial velosity of absorption line and the whole object have allowed simple to define the direction of radial movement - itis compression. ...

... We have calculated the binary coalescence rate with time using the ``Scenario Machine'' code, which allows us to simulate evolution of large ensembles of binary stars in an artificial galaxy using a Monte Carlo method (see Lipunov 1992, Lipunov et al 1994, 1995 and references therein). ... The source evolution in a galaxy with given star formation rate is thus calculated as , where is the redshift at the turn-on of star formation, which is the second important parameter of the model. ...

Starbursts are regions of enhanced star formation efficiency, where gas is being converted into stars at much higher rates than can be sustained over billions of years. ... A nice example in the southern sky is the nearby galaxy NGC 7552, which was imaged with the Compact Array at 3 cm by Forbes et al. ... On 9 May we re-observed this galaxy with the Compact Array in the 3-mm lines of HCN and HCO + . ... The two lines were observed simultaneously, allowing a direct comparison of their line strengths. ...

All stars are formed deep inside molecular clouds. One of the current enigmas lies in the formation and evolution of molecular clouds, specifically the conversion from atomic to molecular gas. ... In July of 2005 GALFA mapped about 300 square degrees of the Taurus Molecular Cloud (TMC) complex yielding the largest high-resolution 21cm map of a star forming region, while using less than 40 hours of observing time. ...
