Berlin, 2 nov (EFE).- An international team of astronomers has captured images of the huge structures in the form of towers that are in the interior of the Carina nebula, an immense cloud of dust and gas within a center of star formation that is located approximately 7,500 light-years away.
they Seem to be, as he explained today in a press release from the European Southern Observatory (ESO), the “pillars of destruction”, in contrast with the nickname of the iconic “pillars of creation” from the Eagle nebula, of a similar nature.
The images show massive stars which destroy the clouds of dust and gas from which they are born.
These forms of the southern-were observed by a team led by Anna McLeod, a doctoral student in THAT, using the integral field spectrograph MUSE, installed on the telescope for long-range (VLT, for its acronym in English) in the Paranal Observatory, in Chile.
Her work, published in the journal Monthly Notices of the Royal Astronomical Society, combined the images obtained with others that show similar structures like the famous “pillars of creation in the Eagle nebula.
The study shows a clear link between the radiation emitted by massive stars nearby, and the characteristics of the own pillars.
One of the first consequences of the formation of a massive star, with powerful ionizing radiation, is that it begins to destroy the cloud in which he was born.
The idea that massive stars have a considerable effect on its environment is not new, however, it is very difficult to obtain observational evidence of the interaction between these stars and their environment.
The team analyzed the effect of this radiation energy in the a-pillars through the fotoevaporación, which concluded that there was a clear correlation between the amount of ionizing radiation emitted by the nearby stars and the dissipation of the pillars.
According to the Observatory, not yet well understood the complexity of the feedback mechanisms between the stars and the pillars, an aspect that will continue to study in the future. EFE
