NEW YORK: The supercomputer simulation of the planet and debris disk around Beta Pictoris shows that the planet’s motion drives spiral waves throughout the disk, a phenomenon that causes collisions among the orbiting debris.
An incredible new computer simulation by NASA shows the planet and debris disk around the nearby star Beta Pictoris in motion.
The supercomputer simulation of the planet and debris disk around Beta Pictoris shows that the planet’s motion drives spiral waves throughout the disk, a phenomenon that causes collisions among the orbiting debris.
“We essentially created a virtual Beta Pictoris in the computer and watched it evolve over millions of years,” said Erika Nesvold, an astrophysicist at the University of Maryland, Baltimore County, who co-developed the simulation.
“This is the first full 3-D model of a debris disk where we can watch the development of asymmetric features formed by planets, like warps and eccentric rings, and also track collisions among the particles at the same time,” Nesvold said.
In 1984, Beta Pictoris became the second star known to be surrounded by a bright disk of dust and debris. Located only 63 light-years away, Beta Pictoris is estimated to be 21 million years old, or less than 1 per cent the age of our solar system.
In 2009, astronomers confirmed the existence of Beta Pictoris b, a planet with an estimated mass of about nine times Jupiter’s, in the debris disk around Beta Pictoris.
Travelling along a tilted and slightly elongated 20-year orbit, the planet stays about as far away from its star as Saturn does from our Sun.
