原行星盘中气体的观测诊断

Observational diagnostics of gas in protoplanetary disks

Andres Carmona

摘要:

原行星盘主要由气体组成(99%的质量)。然而,相对较少的观测约束存在的气体在磁盘。在这篇评论中,我讨论了几个观测诊断的紫外线,光学,近红外,中红外,(分)毫米波长已被用来研究气体的磁盘中的年轻恒星物体。我专注于探测圆盘内部20 AU的诊断,这是行星有望形成的区域。我讨论了每种气体示踪剂的潜力和局限性,并对未来的研究提出了展望。

英文摘要:

Protoplanetary disks are composed primarily of gas (99% of the mass). Nevertheless, relatively few observational constraints exist for the gas in disks. In this review, I discuss several observational diagnostics in the UV, optical, near-IR, mid-IR, and (sub)-mm wavelengths that have been employed to study the gas in the disks of young stellar objects. I concentrate in diagnostics that probe the inner 20 AU of the disk, the region where planets are expected to form. I discuss the potential and limitations of each gas tracer and present prospects for future research.
