Unlike most hypervelocity stars, which are hot, blue, and intrinsically bright, US 708 is hot, blue, and intrinsically modest.
"This will help find hundreds or thousands of hypervelocity stars, understand their origin in much more detail, and use them to investigate the Galactic centre environment as well as the history of our Galaxy," he adds.
Astronomers first thought that the hypervelocity stars, which are large blue stars, may have been expelled from the centre of the Milky Way by a supermassive black hole.
Fragmentation of centimeter-size hypervelocity projectiles on stand-alone metallic meshes was experimentally studied in [5, 6].
The distribution of the debris cloud and the damage of double honeycomb sandwich panel were simulated under oblique hypervelocity impact.

This includes services in the areas of propulsion system testing; materials and components testing; hypervelocity impact testing; critical flight hardware processing and refurbishment; composite pressure systems testing and analysis; operation and maintenance of on-site laboratories and facilities; and emergency services.
He noted that the office was working on advanced navigation for smart weapons using micro-cameras and sensors; missile-defense systems using hypervelocity projectiles; and swarming drones that are "really fast, really resistant."
They've also got a project on gun-based missile defense, where we're taking some of the same hypervelocity smart projectiles that we developed for the electromagnetic gun.
Firstly, the impact sequence of the debris and the propagation characteristics of the signals emitted by PAE sources have been analyzed by introducing the corvonato debris cloud model, the relation of the debris cloud structure characteristics and the debris cloud AE source time sequence characteristics was established, a concept of most fast ring was proposed, and hypervelocity impact (HVI) test was carried out to verify the most fast ring concept.
