In research published this week in Astrophysical Journal Letters, Dr Zoe Leinhardt and colleagues from Bristol's School of Physics have completed computer simulations of
the early stages of planet formation around the binary stars using a sophisticated model that calculates the effect of gravity and physical collisions on and between one million planetary building blocks.
I study
the early stages of planet formation, where microscopic dust particles coagulate to form planetesimal - size bodies.
Though astronomers have cataloged thousands of planets orbiting other stars, the very
earliest stages of planet formation are elusive because nascent planets are born and embedded inside vast, pancake - shaped disks of dust and gas encircling... Read more

However, when you look at all the «big picture» evidence
