Star Formation from Galaxies to Globules
The origin of the empirical laws of galactic-scale star formation are considered in view of the self-similar nature of interstellar gas and the observation that most local clusters are triggered by specific high-pressure events. The empirical laws suggest that galactic-scale gravity is involved in the first stages of star formation, but they do not identify the actual triggering mechanisms for ...
متن کاملStar formation in globules in IC 1396
We present a large-scale study of the IC 1396 region using new deep NIR and optical images, complemented by 2MASS data. For ten globules in IC 1396 we determine (H-K, J-H) colour-colour diagrams and identify the young stellar population. Five of these globules contain a rich population of reddened objects, most of them probably young stellar objects. Two new HH objects (HH 865 and HH 864) could...
متن کاملMagnetic Fields in Star Formation: from Galaxies to Stars
Magnetic fields are important at every scale in the star formation process: from the dynamics of the ISM in galaxies, to the collapse of turbulent molecular clouds to form stars and in the fragmentation of individual star forming cores. The recent development of a robust algorithm for MHD in the Smoothed Particle Hydrodynamics method has enabled us to perform simulations of star formation inclu...
متن کاملStar formation in galaxies and star clusters
This thesis is devoted to star formation from galaxy-scales (≈ 10 000 pc) to sub-star cluster-scales (≈ 0.1 pc). I develop and test a new method to derive star formation histories of Galaxies from their star cluster content, in particular the most massive star clusters. This is followed by an application of this method to the Large Magellanic Cloud, where the results of this new method are conf...
متن کاملStar Formation in Ring Galaxies
Ring galaxies are specific types of interacting galaxies in which a smaller galaxy has passed through the center of the disk of another larger galaxy. The intrusion of the smaller galaxy causes the structure of the larger galaxy to compress as the smaller galaxy falls through, and to recoil back after the smaller galaxy passes through, hence the ring-like shape. In our research, we studied the ...
