Our stellar parameters are broadly consistent with previous work on these objects. From deep HST/ACS imaging of M32 Monachesi et al. (2012) inferred two dominant ...

Oct 26, 2017 ... whose orientation is defined by the current satellite positions. Proper motion measurements, available for all of the 11 classical satellite galaxies, reveal that this is indeed the case (Metz et al. 2008; Pawlowski & Kroupa. 2013). Eight of the 11 satellites are consistent with orbiting in the VPOS, with Sculptor ...

The derived velocity dispersion of (0.38 ± 0.12) km s–1 of the 16 definite member stars is in agreement with the theoretical prediction for the classical Newtonian case according to Baumgardt et al. In order to exclude the possibility that a peculiar mass function might have influenced our measurements, we derived the  ...

A lack of high-mass stars may also account for the lack of high- luminosity H II regions in dwarfs and LSB galaxies (Helmboldt et al. 2005, 2009). Yet Schombert et al.

To extend the benzenethiolate library, we plot the IE versus calculated 4-R-S dipole taken from a separate data set collected by Bent et al. ( Fig.

For our H IPPARCOS RHB stars this is illusionary, since the sample is complete out to perhaps 100 pc (see Sect. 3.2.4). However, the kinematics of the RHB stars also give information about past and future locations. We will calculate the galactic orbits (as in de Boer et al. 1997; Altmann et al. 2004) of the RHB stars and ...

3). Thirdly, many binary systems are expected to be destroyed in clusters (Kroupa 1995a,b; Kroupa et al. 2003; Goodwin & Whitworth 2007 ... -Ophiuchi molecular cloud. They found that the high-mass slope of the CMF matched that of the IMF. This result has been confirmed for Ophiuchus (Johnstone et al. 2000; Young et al .
