How does a star cluster of more than few 10,000 solar masses form? We present the case of the cluster NGC 346 in the Small Magellanic Cloud, still embedded in its natal star-forming region N66, and we propose a scenario for its formation, based on observations of ...
The youngest stellar population (~3 +/- 1 Myr) is associated with the NGC 346 cluster. It includes a rich component of low mass pre-main sequence stars mainly concentrated in a number of sub-clusters, spatially co- located with CO clumps previously detected by Rubio et al. (2000). ...
It is noted that the Lyman continuum radiation from a cluster of OB stars will drive ionization (I) fronts into nearby neutral material and that an I front... BG Elmegreen,CJ Lada - 《Astrophysical Journal》 被引量: 1059发表: 1977年 Far Ultraviolet Spectroscopic Explorer Observations of a ...
We present the results of our investigation of the intermediate-age star cluster BS 90, located in the vicinity of the H II region N66 in the SMC, observed with HST ACS. The high-resolution data provide a unique opportunity for a very detailed photometric study performed on one of the rare...

About one hour on Rosette (346 x 10sec), from city center balcony at mag 17.30, foggy night. Lazy processing in Pixinsight. and the shooting place : Wow, looks 3D, like the cluster is floating in front of the nebula. Stevan Klaas likes this #3803 Stevan Klaas Explorer 1 Posts: 69...
We present a cluster analysis of the bright main-sequence and faint pre--main-sequence stellar populations of a field ~ 90 x 90 pc centered on the HII region NGC 346/N66 in the Small Magellanic Cloud, from imaging with HST/ACS. We extend our earlier analysis on the stellar cluster popula...
The variations are inherent to the cluster environment and not an effect of stellar internal processes, as even unevolved stars show abundance variations [312]. A coherent picture that explains all observed abundance variations (involving elements ranging from He to K, and Fe-peak elements in ...
Nearby galaxies offer unique laboratories allowing multi-wavelength spatially resolved studies of the interstellar medium, star formation and nuclear activity across a broad range of physical conditions. In particular, detailed studies of individual local luminous infrared galaxies (LIRGs) are crucial for ...
