“While the stars are born and die”
“Scientists have managed to study how a star is born right next to another, older, star. The star was born much in the same way as our own earth formed.”
“With the help of which the Alma (Atacama Large Millimeter Array), astronomers have gained a unique insight into how it can go when a star is born.”
“When they studied a massive protostar by the name of MM 1a, they discovered that there also was another object, a much younger star who, consequently, received the name MM 1b and which was formed from the disc of gas and dust that orbited around the star.”
” Stars are formed from huge clouds of gas and dust in interstellar space. When those clouds collapse due to gravity, they begin to rotate increasingly rapidly, which is formed as a disk around the star. Around the lighter stars, like our own sun, it is from this disk that planets are formed. In this case, however, is the star of the heavy. So instead of a planet, we can see that the further a star is born, ” says John Ilee University of Leeds.”
“By measuring the amount of radiation and calculate the subtle differences between the different ljusfrekvenser, the researchers were able to calculate the mass of both the MM-1a and MM-1b.”
“the Research, now published in the Astrophysical Journal Letters, shows that MM-1a weighs around 40 times as much as our own sun, while the MM 1b only half as heavy as the sun.”
“– Many of the older, heavy, stars have a nearby ”
“MM 1b may very well have your own slice of gasstoft from which it very well may be forming planets. But in this case it is in a hurry, points out John Ilee.”
“– Stars as heavy as the MM 1a only live for around a million years before they explode in a powerful supernova, so even if MM 1b have the opportunity to form their own planetary systems, it will not remain for long.”
“in Which Alma (the Atacama Large Millimeter Array) consists of 66 interconnected radio telescopes in the Atacama desert in Chile. The telescope was inaugurated in 2013 and is the world’s largest project in ground-based astronomy.”
“Which will give humanity the csto activities in the universe, and answers to astronomy questions. Among other things, shall examine the universe’s beginning, test Einstein’s theory of gravity and the search for alien intelligence.”
“A number of countries and organisations is involved in the telescope, including the ESO, the European Space Organization, in which Sweden is participating.”
