Scientists from the University of Sheffield have uncovered a new path to study ancient stars, neutron stars, white dwarfs, and black holes. The new path helped explain the evolution of ancient stars recently, thanks to a high-speed, multicolor camera technology.
The technology known as HiPERCAM snaps over 1000 pictures per second. This capability allowed the team to measure both the radius and the mass of a cool subdwarf star, in a first attempt of its kind.
Using the large terabytes of data from the research, the researchers verified the prevalent stellar structure model. The model describes the internal structure of a star in detail. However due to technology limitations, scientists could only capture a single picture every few minutes.
The study published in Nature Astronomy on April 8, provides an insight in brightness of stars. Furthermore, it promises to delight science enthusiast with vivid and colorful representation never before witnessed. And most importantly, it provides a much-awaited answer to the future evolution of ancient stars.
Blackholes May Finally See the Light of the Day
The HiPERCAM technology also allows multi-color image capturing simultaneously. This will enable scientists to study explosions and eclipses in-depth. The technology captures events in five different colors and captures movement at every millisecond.
This breakthrough solves a major challenge related to studying the black holes. By nature, black holes are so massive that light rarely, if ever escapes it. Hence, studying black holes with naked eye was a major challenge.
The new technology promises to shed light on the massive size of black holes and their shape. Black holes are supersized, sometimes as big as billions times the sun. Additionally, scientists have little idea about the formation of this massive size.
The research was aided by a 3.5 million euro grant from the European Research Council (ERC).
