E isso tem causado uma certa confusão, pois muitos acham que o Sol vai acabar a sua vida do mesmo jeito. Isso não é verdade, eu já falei várias vezes, mas vou repetir. A linha de vida que uma estrela segue depende da sua massa, estrelas de grande massa como Betelgeuse, vivem pouco e acabam a vida como uma supernova. Estrelas como o Sol, que não têm tanta massa assim seguem outra linha. Quando o combustível do Sol acabar, ele irá crescer e irá se transformar numa estrela conhecida como gigante vermelha. Essa gigante vermelha então irá começar a perder suas camadas mais externas deixando para trás só um caroço, que chamamos de anã branca. Para conhecer os detalhes da fase final da vida de uma estrela, os astrônomos precisam observar muitas estrelas, e estrelas em estágios finais. E assim, eles acabam descobrindo que nem tudo é tão simples assim. Existe um sistema estelar conhecido como HD101584, que é bem peculiar. Esse sistema é composto por uma estrela grande e por uma companheira menor. Quando a estrela maior estava morrendo a estrela menor foi engolida pela gigante vermelha. E a partir daí começou uma verdadeira batalha estelar. Quando a estrela maior se transformou numa gigante vermelha ela cresceu tanto que engoliu a estrela menor. Essa estrela menor começou então a espiralar em direção ao núcleo da estrela maior. Mas não chegou a colidir com o núcleo. Essa manobra acabou desencadeando uma explosão na estrela maior, que espalhou suas camadas de gás e deixou o seu núcleo exposto. O resultado disso, são as belas imagens feitas pelo ALMA e pelo APEX, onde é possível ver uma nebulosa com uma complexa estrutura de gás e jatos, tudo isso resultado desse processo de batalha entre as duas estrelas. Os jatos lançados sobre o material que já estava ali criou as bolhas azuis e avermelhadas que observamos nas imagens. Além de ser uma imagem muito bonita e interessante, essa imagem é muito importante para os astrônomos. Através dessa imagem, os astrônomos podem entender melhor a fase final de vida de estrelas como o Sol. Estudar o sistema binário como esse faz com que os astrônomos possam encontrar peças para o complexo quebra-cabeça que é entender a transição entre os estágios de evolução das estrelas. Os astrônomos poderão estudar o link entre a gigante vermelha que existia até então, e o que irá restar da estrela. Tudo isso só foi possível graças à grande sensibilidade do ALMA. O legal mesmo será quando o ELT de 30 metros for inaugurado no Chile, esse gigantesco telescópio nos dará uma imagem do que está acontecendo no coração desse objeto. E os astrônomos assim poderão examinar de perto a batalha entre as estrelas.

Young Stars In Old Cluster Challenging Understanding Of Cosmic Evolution

Astronomers have discovered young stars in an old cluster in our neighborhood – Large Magellanic Cloud. Where is the catch perhaps you wonder? In the core of our understanding of cosmic and stellar evolution. New observations and study challenge it.

Stars Evolution

To see how this finding messed up with our current knowledge of stellar evolution we have to back on its formation. As an example, we can take Milky Way clusters. Star clusters, which are the group of stars bounded by gravity, contains the stars made of the same cloud of molecular gas formed at roughly the same time. So each cluster has its own same aged stars. That is what every previous observation have shown and based on that the model of stellar evolution is built.

Typical star cluster M4 which is one of the largest globular star clusters in our galaxy containing over 10,000 stars

Now astronomers confront with an unexpected situation. Scientists from the University of Western Australia used Spitzer telescope and thanks to its infrared wavelengths they managed to capture 15 very young stars comparing to other ones in our third closest galaxy Large Magellanic Cloud. To be weirder, 7 of them are located in the center of the cluster. Scientists are now confused and not sure how to explain this. Firstly they thought that these stars are formed from molecular gas leaking into the cluster from interstellar space. However, after radio telescope observations it is eliminated due the lack of correlation between interstellar hydrogen gas and the location of the clusters astronomers were studying.

Dr. Bi-Qing For, from the International Centre for Radio Astronomy Research in Perth, believes that these younger stars have actually been created out of the matter ejected from older stars as they die. This would mean researchers have discovered multiple generations of stars belonging to the same cluster.

This isn’t the first time that classic model of stellar evolution is put to the test. Back in 2007, Hubble Space Telescope discovered a large number of stars in the same galaxy, that have diverse characteristics. Australian team hopes that Hubble will be pointed to the studied clusters and allows that to finally confirmed that is possible that star clusters can contain several generations of stars.
