Vlt Extra Stars
New facilities and technologies have advanced our understanding of massive stars significantly over the past 30 years. Here I introduce a new large survey of massive stars using VLT-FLAMES, noting the target fields and observed binary fractions. These data

Figure 15: The protoplanetary disks around the R CrA (left) and HD45677 (right) stars, captured with ESO’s VLT (Very Large Telescope) Interferometer. The orbits are added for reference. The star serves the same purpose, since its light was filtered out to get a more detailed image of the disk (image credit: Jacques Kluska et al.). The VLT® HVAC Drive FC 102 series, 1.1-90 kW, complies fully with the require-ments of the metering systems as outlined in the NABERS rules for collecting and using data, as follows: Nabers rating Performance comparison 6 stars Market leading building performance 5 stars Excellent building performance 2.5 – 3 stars Market average building. The roller brake tester can test the braking systems of wheeled vehicles with an axle load of up to 16,000 kg (VLT 16733 models) or 20,000 kg (VLT 20733 models). Testing can be carried out in both forward and reverse directions, for service, secondary, transmission and applied parking with opposite rotation (vehicles with fixed 4-wheel drive).
