After a Dark Start, the Sligo Neighbors have made a Star Game


When he came to cast out the stars, the galactic neighbors got out of it; closer to the beginning slowly. But they're now upgrading speed.

By doing a & # 39; The first detailed chemicals of disease beyond our scientists found that the creation of the stars in the Clouds Small and Small Magellanic Clouds has emerged in the recent past, after a weak. Not only does the new products provide a vision of the most varied diseases in the & # 39; globally, and they also help to & # 39; developing an understanding of the success of the Sea Channel.

Although the Magellanic Small (Small and Small Magellanic Clouds) (LMC and SMC) Clouds are only 150,000 years old from the Flying Bowling – the next door, scientifically – it's time to The sciences are very tough to be in; do their job. [Dizzying Array of Stars Dazzles in New Hubble Photo]

"It's been challenging to map out the whole structure," said David Nidever, a rhetorologist at the State University of Montana, to last month's reporters at a 233rd meeting of the American American Regimental Society. Nidever and its Apache Point Experiment Evolution Experiment 2 (APOGEE-2) laboratory survey colleagues have used to get detailed ideas of 5,000 stars in the Magellanic Clouds. By mapping out the serious elements that are spread through the stars in the # 39; disease, the engineers were able to make a model about when the generations of the stars were born.

"With this new capability, we can explore the Clouds Magellanic as ever before," said Nidever.

Only visible from the South Glossary, the LMC and SMC were nominated for the explorer Ferdinand Magellan, who was in charge of his first European tour; circulation of the globe. The pair of dwarf galaxies, smaller star concentrations that can include anywhere between 1,000 and 1,000,000,000 times the sun's mass in gas, dust and star, according to Nidever paper on the new job. The Killicone is surrounded by dozens of known disease diseases and scientists believe that more people have a lot of people. hiding in the beds, creating a small shape, making them very difficult to find.

Although they are suitable as dwarf galaxies, the LMC and SMC are unusual, which build stars more slowly than each other. The difference has been a long-term confidentiality for scientists.

"There should be a relationship between disease levels and star staring," said Nidever to "The Magellan waters disperse that move."

The Sloan Digital Survey Survey APOGEE-1 survey was surveyed on the Beautiful Hemisphere Route from 2011 to 2014, which provides a "unprecedented vision of the dynamic structure and the chemical history of the galaxy", which Sloan website. Based in New Mexico, the first version of APOGEE was restricted to the North Hemisphere.

In 2017, the almost similar APOGEE-2 instrument was installed at the Las Campanas Theater in Chile. The instrument began to view the LMC and SMC the same year.

The first stars were created from an intense cloud of hydrogen and helium, which converts a small percentage of the gas into poor elements. When they were broken into violent supernovas, they removed the environment with those elements, which were introduced into the next generation of stars, and the bike continued – with every generation of stars; doing more and more go to poor elements.

With APOGEE-2, Nidever and his colleagues were able to try to make chemicals of thousands of stars in the LMC and SMC. The scams inserted into & # 39; Replicated to find out how long it created a generation of stars. So they were able to rebuild the history of creating the stars of both galaxies.

Unlike Slighe na Finne, the Magellanic Games went out to slowly ill, and starred new 50 times more slowly than our own disease, Nidever said. But despite the first torch, the LMC had been hitting recently with six-fold worship in new star.

"It's never been too late to be active," said Nidever.

What happened to the recent recent, which happened about 2 billion years ago? Nidever said it was the most likely source that the SMC had recently been attacking the disease into the larger dwarf galaxy.

"We see features that they have interacted in their structure," said Nidever.

Clouds have a slow time compared to other dwarf galaxies around the Beautiful Way. Evening stroke levels are even lower than expected for large, Nidever said.

"That's a secret," he said.

The difference that appears to come from different environments. Most of the dwarf galaxies that have been explored so far have taken several trips around the Ringway. The influential interactions with the galaxy may have helped us to turn to the # 39; ghaze into the stars.

However, it seems that the LMC and SMC will be sending it to; The first time around the Seafarer, according to previous research. That means they have spent about 10 billion years to & # 39; Raising the stars alone, without a great galaxy to stimulate the collision, the researchers said. It was only in the billion years that the two started; They are going to work more frequently with the Milk Way and with each other, and take them as soon as they go. building their stars.

But things just start for the LMC and SMC. In around 2.5 billion years, the LMC will accompany the Mudan Route, and removes stream of star design.

"Lots of stars [in the Magellanic Clouds] thrown into the surname of the Beautiful Way, and it will have a great impact on making its water, "said Nidever.

Multiplication causes a break of star creation in the stainless steel. stay outside and the Metallic Thick dust. After going to the start so slowly, the two will put up the last few years in a storm of firefires.

The search was submitted to the Astrophysical Journal and is available on the roXiv server service.
