Bow-shock induced star formation in the LMC?

نویسنده

چکیده

The structure of supergiant shells, in particular of LMC 4, is hard to explain with stochastic self-propagating star formation. A series of supergiant structures lies along the outer edge of the LMC and form a sequence increasing clockwise in age. We have considered the rotation of the LMC and its motion through the halo of the Milky Way and propose that these structures find their origin in star formation induced in the bow-shock formed at the leading edge of the LMC. Due to the rotation of the LMC these structures then move aside.

Large-scale star formation in the Magellanic Clouds

In this contribution I will present the current status of our project of stellar population analyses and spatial information of both Magellanic Clouds (MCs). The Magellanic Clouds are suitable laboratories and testing ground for theoretical models of star formation. With distance moduli of 18.5 and 18.9 mag for the LMC and SMC, respectively, and small galactic extinction, their stellar content ...

Jet-Induced Emission-Line Nebulosity and Star Formation in the High-Redshift Radio Galaxy 4C41.17

The high redshift radio galaxy 4C41.17 has been shown in earlier work to consist of a powerful radio source in which there is strong evidence for jet-induced star formation along the radio axis. We argue that nuclear photoionization is not responsible for the excitation of the emission line clouds and we construct a jet-cloud interaction model to explain the major features revealed by the detai...

The dynamics of the nebula M 1 - 67 around the run - away Wolf - Rayet star WR 124

(The image quality has been reduced to submit this paper to astro-ph. To get a full resolution version, please visit A new point of view on the dynamics of the circumstellar nebula M1-67 around the runaway Wolf-Rayet (WR) star WR 124 is presented. We simulated the outbursts of nebulae with different morphologies, to compare the results to the observed dynamical spectra of M1-67. We found that i...

Cluster formation versus star formation rates around six regions in the Large Magellanic Cloud

The stellar population and star clusters around six regions in the Large Magellanic Cloud (LMC) are studied to understand the correlation between star formation and cluster formation rates. We used the stellar data base of the OGLE II LMC survey and the star cluster catalogues. The observed distributions of stellar density in the colour−magnitude diagrams (CMDs) were compared with synthetic one...
