WebHigh-redshift star-forming galaxies have very different morphologies compared to nearby ones. Indeed, they are often dominated by bright star-forming structures of masses up to 108-9 M⊙ dubbed 'giant clumps'. However, recent observations questioned this result by showing only low-mass structures or no structure … Webstar formation (Wang et al. 2006). With a typical star formation efficiency, the large amount of dense gas in these IRDCs makes them the natural birth place for massive stars and clusters. Thus, these regions are premium sites for uncovering the initial conditions of massive star and cluster formation.
WebWe perform a study of the spatial and kinematical distribution of young open clusters in the solar neighbourhood, discerning between bound clusters and transient stellar condensations within our sample. Then, we discriminate between Gould Belt (GB) and local Galactic disc (LGD) members, using our previous estimate of the structural parameters of both … WebStar formation is believed to be hierarchical in space and time as a result of turbulence and self-gravity (Scalo 1985;Li et al. 2005; Elmegreen 2010; Kritsuk et al. 2013) within …
Webaccretion, infall and merging, and a monolithic scenario, where star formation is rapid and efficient. We distinguish between these modes by defining a characteristic mini-mum mass, M & 1011M⊙, in our fiducial model, for early type galaxies where star formation occurs efficiently.
