The selective accretion theory chalks it up to high gas density in the early solar system, during the planet's formation.
选择性附加理论写出它的高气体密度在早期太阳系,在行星的形成。
In one - the 'accretion' model - small clumps of dust build up over millions of years to form a planet's solid core, which then pulls gases towards it.
一个被称作‘连生’模型,指尘埃碎块经过数百万年的时间聚集形成了一颗行星的固体核心,之后它将周围的气体俘获据为己有。
Active galaxies give off bright radiation from their cores, where gas heats up as it is compressed into a swirling accretion disk encircling the black hole.
活动星系从它们的核部发出明亮的光芒,在那里,气体被加热并压缩成一个漩涡状的圆盘,漩涡的中心便是黑洞。
Later simulations show that even a companion with an orbit as wide as Neptune's could scoop up an accretion disk.
后来的数值模拟结果显示出,即使伴星的轨道半径大如海王星的轨道,它仍可汲取物质而形成吸积盘。
