Cold, old and metal-poor: New stellar substructures in the Milky Way's dwarf spheroidals
V. Lora, E. K. Grebel, S. Schmeja +1
Dwarf spheroidal galaxies (dSph) orbiting the Milky Way are complex objects often with complicated star formation histories and internal dynamics. In this work, we search for stell…
Structure and mass segregation in Galactic stellar clusters
Sami Dib, Stefan Schmeja, Richard J. Parker
We quantify the structure of a very large number of Galactic open clusters and look for evidence of mass segregation for the most massive stars in the clusters. We characterise the…
Massive stars reveal variations of the stellar initial mass function in the Milky Way stellar clusters
Sami Dib, Stefan Schmeja, Sacha Hony
We investigate whether the stellar initial mass function (IMF) is universal, or whether it varies significantly among young stellar clusters in the Milky Way. We propose a method t…
Global survey of star clusters in the Milky Way III. 139 new open clusters at high Galactic latitudes
S. Schmeja, N. V. Kharchenko, A. E. Piskunov +4
An earlier analysis of the Milky Way Star Cluster (MWSC) catalogue revealed an apparent lack of old (> 1 Gyr) open clusters in the solar neighbourhood (< 1 kpc). To fill this gap w…
Hierarchically Clustered Star Formation in the Magellanic Clouds
Dimitrios A. Gouliermis, Stefan Schmeja, Volker Ossenkopf +2
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 Sma…
The clustered nature of star formation. Pre--main-sequence clusters in the star-forming region NGC 602/N90 in the Small Magellanic Cloud
Dimitrios A. Gouliermis, Stefan Schmeja, Andrew E. Dolphin +3
Located at the tip of the wing of the Small Magellanic Cloud (SMC), the star-forming region NGC602/N90 is characterized by the HII nebular ring N90 and the young cluster of pre--ma…
