“…HK Ori is extensively discussed in Baines et al (2004) and is not shown here. V380 Ori was also observed by Bailey (1998), who found a PA = 2067 ± 11, and a positional displacement of 0.039 ± 0.003 arcsec to the north‐east.…”

“…In principle, the method can be applied across any spectral line in which the intensity ratios of the two stars change from the continuum ratio; in the case of an absorption line, the peak position will move away from the star displaying the absorption. Previously, we reported on data of the pre‐main‐sequence binary HK Ori (Baines et al 2004); the aim of the present work is to further develop the technique and apply it to a large sample of Herbig Ae/Be stars. We observed 28 young Herbig Ae/Be stars and three F‐type pre‐main‐sequence stars spectro‐astrometrically.…”

We present high resolution spectro-astrometry of a sample of 28 Herbig Ae/Be and 3 F-type pre-main sequence stars. The spectro-astrometry is shown from both empirical and simulated data to be capable of detecting binary companions that are fainter by up to 6 magnitudes at separations larger than 0.1 arcsec. The nine targets that were previously known to be a binary are all detected. In addition, we report the discovery of 6 new binaries and present 5 further possible binaries. The resulting binary fraction of 68+/-11 per cent is the largest reported for any observed sample of Herbig Ae/Be stars, presumably because of the exquisite sensitivity of spectro-astrometry for detecting binary systems. The data hint that the binary frequency of the Herbig Be stars is larger than for the Herbig Ae stars. The appendix presents model simulations to assess the capabilities of spectro-astrometry and reinforces the empirical findings. Two objects, HD 87643 and Z CMa, display evidence for asymmetric outflows. Finally, the position angles of the binary systems have been compared with available orientations of the circumprimary disc and these appear to be co-planar. The alignment between the circumprimary discs and the binary systems strongly suggests that the formation of binaries with intermediate mass primaries is due to fragmentation as the alternative, stellar capture, does not naturally predict aligned discs. The aligment extends to the most massive B-type stars in our sample. This leads us to conclude that formation mechanisms that do result in massive stars, but predict random angles beween the binaries and the circumprimary disks, such as stellar collisions, are also ruled out for the same reason.Comment: MNRAS accepted, 18 page

“…This US conflict not only stimulated emigration demands but also caused a cotton famine in Lancashire that incited people to leave. Also, Australia offered inducements to friends and relatives (of settlers) to emigrate, including some prosperous persons, although as numbers migrating increased so did the proportion of labourers and unskilled (Baines, 1985). In 1869, following acute economic problems in England and Wales, numbers leaving exceeded those leaving Ireland for the first time.…”

“…These joint movements of capital and labour from the UK are topics much discussed in economic history literature. The scholarly works of Cairncross (1953), Thomas (1973) and Baines (1985) deal with related issues, and while we draw on their views and those of their critics, the present analysis is focused more narrowly on the relation between the respective types of factor movements. These are normalized measures of the factor flows which indicate, for labour, the intensity of emigrations relative to population size and, for capital, the intensity of capital exports relative to the size of the economy as measured by nominal GNP.'…”

"This paper is concerned primarily with examining the nature of linkages between capital and labour emigration from the U.K. We also consider whether the primary impulses for emigration were push or pull influences--the main intent is to look at the relation between the flows rather than the determinants of either. The nature of the capital-labour link is examined qualitatively using historical argument and quantitatively using statistical tests and causality analysis. The starting time for analysis is the end of the Napoleonic Wars when useful data became available." (SUMMARY IN FRE AND SPA)

Bronze age burials within the Morava, Nisava and Timok basins

Following more than seven decades of research on the Bronze Age cremation burial grounds in the territory of Serbia, the new absolute dates provide us with an opportunity to determine a more precise chronological sequence of different local cultural manifestations. Although the pioneers of the Serbian archaeology after WWII defined the main cultural trajectories that led to the establishment of cremation as the main burial rite during the 2nd millennium BC, several misconceptions were established that need to be corrected, considering new data. We regard this paper as our contribution to the better understanding of the cultural and chronological sequence in the Central Balkans during the Bronze Age.
