What type of stars is the double star?

How was the Milky Way galaxy formed?
The "Big Bang" created the Universe and the first stars. Not long after, these stars began to contract due to gravitational attraction, possibly from the remnants of the first population III stars.These stars, created the early Milky Way. Since then, new stars have been formed - including our own Sun.
