How to observationally diagnose planet formation process:dust evolution and gas dispersal mechanisms in protoplanetary disks

随着最近系外行星的发现和对原行星盘详细观测的发展，我们研究了盘中尘埃和气体的演化，它将变成类地行星和木星行星，它的环境效应，以及它对观测性质的影响。我们的模型计算与全新观测结果的比较表明，圆盘表面存在细小的尘埃颗粒和湍流混合。此外，我们的模型计算表明，用阿塔卡马大毫米/亚毫米阵列(ALAM)进行的分子线观测将揭示各种气体从盘中扩散的机制。

Following the recent discovery of exoplanets and development of detailedobservations of protoplanetary disks, we have studied evolution of dust and gas in the disks, which will turn into Terrestrial and Jovian planets, its environmental effects, and its effects on observational properties. Comparison between our model calculations with brand-new observations suggests existence of small dust grains and turbulent mixing in the disk surfaces. Also, our model calculations suggest that molecular line observations with the Atacama large millimeter/submillimeter array (ALAM) will revealvarious gas dispersal mechanisms from disks.
