In fact, half of the calcium in the universe likely came from calcium-rich supernovae. But these explosions have turned out to be incredibly rare events that scientists have had difficulty observing and analyzing, so they weren't sure how the calcium was created.like gold and platinum.That changed when a global team of almost 70 scientists from around the world collaborated after receiving a tip from an amateur astronomer. The study published Wednesday in The Astrophysical Journal.
They requested that Keck observe the event in optical light, while University of California Santa Barbara graduate student Daichi Hiramatsu used the Swift observatory to observe it in X-ray and ultraviolet light. "The stars responsible for calcium-rich supernovae shed layers of material in the last months before explosion," Jacobson-Galan said."The X-rays are the result of the explosion violently colliding with this ejected material and stimulating a brilliant burst of high energy photons."
This occurs because the hot ball of material created by the explosion is trying to reach an equilibrium with its environment, Jacobson-Galan said.
