Density distribution Thestellar density near the Sun The density distribution ofstarsnear theSuncan be used to calculate the mass density of material (in the form of stars) at the Sun’s distance within the Galaxy. It is therefore of interest not only from the point of view of stellar stati...

Local Group, in astronomy, the group of more than 20 galaxies to which the Milky Way Galaxy belongs. About half are elliptical galaxies, with the remainder being of the spiral or irregular type. As in other clusters of galaxies, members are probably kept
Major observational and theoretical challengesneed to be addressed in determining the processes responsible for convertingthe low-density ISM into dense molecular clouds, forming dense filaments andclumps, fragmenting them into stars, OB associations and bound clusters, andcharacterizing the feedback that ...
Stars escaping globular clusters form thin, long and kinematically-cold tidal streams. In pristine conditions, these streams have nearly uniform density, h... A Bonaca - Aps April Meeting 被引量: 0发表: 2019年 加载更多研究点推荐 Milky Way Halo ...
The inner and outer sub-samples covering Galactocentric radii R = 4.2–8.1 kpc and 8.9–13.5 kpc, respectively, are consistent with the GCMF, once the exponential decline of the Galactic disc density is taken into account. The model suggests star formation with low efficiency of 15–20%...
"These stars shouldn'tlive long enough to reach the distant outskirts of the Milky Way, so weshouldn't expect to find them there. The density of stars in the outer regionis much less than in the core, so we have a better chance to find these unusualobjects." Theresults of this study...
Results. In total we discovered 782 density enhancements, 524 of which were classified as real objects. Among them 139 are new open clusters with ages 8.3 < log (t [yr]) < 9.7, distances d< 3 kpc, and distances from the Galactic plane 0.3 <Z< 1 kpc. This new sample has increased ...
