Blue supergiants are some of the most magnificent objects in the entire universe. These objects are giant stars with an accelerated lifespan, as they live shorter life in comparison to other stars, a trait which renders them difficult to track down and observe, even when modern technology is used.
In the past, the number of known supergiants was quite low, and we didn’t know too much about them. A team of British researchers spent over five years on the creation of advanced blue supergiant star simulations which can be used in an attempt to anticipate the factors which determine the unusual aspects of their surface.
While they were working on the interior of the stars the team argued that the surface could be influenced by gravity waves, similar to those observable in the case of oceans. Seismic waves are also an essential factor, and they can be generated freely by the activities which take place within the star.
Astronomers shed more light on blue supergiants
By using data collected from space telescopes a team of Belgian researchers was able to make an important discovery, namely that almost every blue supergiant is influenced by the presence of waves on their surface, with them being able to influence the level of brightness emitted by the star.
The work confirms the assumptions of the previous study since the waves are caused by internal activity. This means that researchers have the chance to learn new information by using asteroseismology, a technique similar to the one employed in the field of regular seismology.
Stars have fascinated humanity since our early ancestors looked towards them for the first time. Telescopes allow researchers to observe the surface of the stars, but they don’t know what is found within them. However, such a task can be completed with the help of modern space telescopes which can record sounds. These sounds are analyzed to provide valuable information about the internal structure of the target star. The results of the latest study were published in a scientific journal.
Karen and her husband live on a plot of land in British Columbia. They aim to grow and raise a significant part of their food by maintaining a vegetable garden, keeping a flock of backyard chickens and foraging. They are also currently planning a move to a small cabin they hand built. Karen’s academic background in nutrition made her care deeply about real food and seek ways to obtain it. Thus sprung Anna’s interest in backyard gardening, chicken and goat keeping, recycling and self-sufficiency.
