In science not everything is applied. Not all lines of research are chosen to try to “save the world.” Some respond to curiosity and this is one of them. When we look out there, it seems that we find a certain correlation between the speed at which the stars turn and their…
Why stars spin down, or up, before they die
From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down." The sun's total angular momentum has declined as material is gradually blown off at the surface as solar wind. By observing this, astronomers have theorized the interaction between magnetic fields and plasma flow to be the most efficient way to spin down stars.
Do stars slow down before they die? New study reveals a surprising twist
Stars may look calm and steady in the night sky, but deep inside they are constantly moving and changing. One of the most important changes is how fast they spin. From the time they are born to the end of their lives, most stars gradually slow down. Scientists call this process “spin down,” and it […] The post Do stars slow down before they die?
