气体内循环

Gaseous Inner Disks

Joan R. Najita, John S. Carr, Alfred E. Glassgold, Jeff Valenti

摘要:

作为行星的可能诞生地和恒星质量积累的重要通道,内盘在恒星和行星形成中具有重要意义。对内部盘的气体成分的研究是感兴趣的,因为它们能够探测该区域的动力学、物理和化学结构以及气体含量。我们回顾了这一领域的观测和理论发展,强调了这些研究的潜力,例如,测量内部盘截断半径,探测盘吸积过程的性质,并绘制盘气体含量的演变图。这类测量有可能为恒星和行星形成的物理过程提供独特的见解。

英文摘要:

As the likely birthplaces of planets and an essential conduit for the buildup of stellar masses, inner disks are of fundamental interest in star and planet formation. Studies of the gaseous component of inner disks are of interest because of their ability to probe the dynamics, physical and chemical structure, and gas content of this region. We review the observational and theoretical developments in this field, highlighting the potential of such studies to, e.g., measure inner disk truncation radii, probe the nature of the disk accretion process, and chart the evolution in the gas content of disks. Measurements of this kind have the potential to provide unique insights on the physical processes governing star and planet formation.
