... Архив семинара . ... Triggered Star Formation" . It is now well established that massive stars in star forming regions can trigger next generation of star formation. ... The young stellar objects (YSOs) in star forming regions have been identified using the near-infrared (NIR) and mid-infrared (MIR) observations. ... The age of YSOs, the morphology of the regions and the global distribution of YSOs indicate that the star formation can be triggered by either (RDI/ CC) of the processes. 40 мин. ...

... As we have seen, evolutionary considerations based on our current understanding of massive binary systems lead to the conclusion that BH+PSR binaries must constitute a rather numerous subclass of all binary PSR ( 1 per 1000 isolated pulsars; Lipunov et al. , 1994b[ 124 ]). It seemed a priori that the binary radio pulsar PSR B0042-73   in the SMC (Kaspi et al., 1994[ 81 ]) could belong to one of these two classes. ... This means that such binary pulsars should be discovered in the near future. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... We have examined the diversity of planets and planetary systems that arise from oligarchic growth and gas accretion onto massive cores, by means of N-body simulations combined with a sophisticated disc model. ... Slow planetary growth resulted from the relatively low mass of solids in the disc, and one consequence of this is that planets underwent limited orbital migration during the lifetime of the gas disc. ... Figure 1 shows an example of this migration behaviour in a single-planetin-a-disc run. ...
