Discs and disc-like structures play a fundamental role in the formation of stars and planets. Due to angular-momentum conservations it is inevitable that discs will build up around young stellar objects during their assembly from collapsing cloud cores. Yet it is not clear during which state discs first appear around protostars and what are the expected observational signatures during the early phases of disc evolution. Also form the theoretical point of few, it is not clear what kind of signatures one should expect from those deeply embedded young protostars surrounded by rotating structures. Hence, the aim of this proposed project is to study the early phases of disc evolution with radiation-transfer magneto-hdyrdodynamical simulations (RT- MHD).

圆盘和类圆盘结构在恒星和行星的形成中发挥着重要作用。由于角动量守恒，在年轻恒星从坍缩的云核组装过程中，盘将不可避免地在其周围形成。然而，目前尚不清楚原恒星周围最初出现的状态盘是在哪个状态下出现的，也不清楚在盘演化的早期阶段预期的观测特征是什么。同样从少数人的理论观点来看，目前还不清楚那些被旋转结构包围的深深嵌入的年轻原恒星会出现什么样的特征。因此，该项目的目的是通过辐射转移磁流体动力学模拟（RT-MHD）研究椎间盘演化的早期阶段。
