AI 中文摘要
原行星盘的演化和消散由吸积、磁驱动喷流和风以及光蒸发风所控制，这从根本上塑造了行星系统。确定这些质量损失过程如何共同演化对于限制行星形成途径至关重要。我们分析了72个倾斜（i>40度）的大多数II类盘的詹姆斯·韦布空间望远镜中红外仪器/积分场单元数据，以识别和表征空间分辨的喷流和风，重点关注[NeII]和H2线。在66个盘中检测到H2 S(1)、S(3)、S(5)、S(7)和/或[NeII]的扩展发射，揭示了不同的形态。我们开发了一个框架来识别锥形H2风以及垂直于盘的高速[NeII]喷流，分别在46个和40个盘中检测到它们。所有有[NeII]喷流的源都表现出在H2（85%）或[OI]中追踪到的相应风，建立了喷流和风之间的联系。[NeII]喷流和H2风的检测率与质量吸积率呈正相关，与盘倾角或恒星质量无关。相反，在较低吸积体中优先发现边缘分辨的低速[NeII]风。在有H2风的源中，由S(7)和S(5)追踪到的较热风的检测随着吸积率的降低比冷的S(1)成分下降得更快。与高分辨率[OI] 6300Å光谱的比较表明，[OI]低速度成分和扩展H2风的检测优先朝向中等到高吸积体（>~10^-8.5~Msun/yr），而较低吸积体仅表现出[OI]和[NeII]风。这些结果共同表明，与磁流体动力学盘风起源一致的原子喷流和原子+分子风在早期、活跃吸积的盘阶段占主导，而在较低吸积率下，喷流减弱，风主要变为原子的。
英文摘要
The evolution and dispersal of protoplanetary disks--governed by accretion, magnetically launched jets and winds, and photoevaporative winds--fundamentally shape planetary systems. Determining how these mass-loss processes co-evolve is crucial for constraining planet formation pathways. We analyze archival JWST/MIRI/IFU data of 72 inclined (i>40deg) mostly ClassII disks to identify and characterize spatially resolved jets and winds, focusing on [NeII] and H2 lines. Extended emission in H2 S(1), S(3), S(5), S(7) and/or [NeII] is detected toward 66 disks, revealing diverse morphologies. We develop a framework to identify conical H2 winds and high-velocity [NeII] jets perpendicular to the disk, detecting them toward 46 and 40 disks, respectively. All sources with [NeII] jets exhibit a corresponding wind traced in either H2 (85%) or [OI], establishing a connection between jets and winds. The detection fractions of [NeII]-jets and H2-winds correlate positively with mass accretion rate, with no dependence on disk inclination or stellar mass. Conversely, marginally resolved low-velocity [NeII] winds are found preferentially toward lower accretors. Among sources with H2 winds, detection of hotter winds traced by S(7) and S(5) declines more rapidly with decreasing accretion rate than the colder S(1) component. Comparison with high-resolution [OI]6300\textÅ spectroscopy reveals [OI] LVC and extended H2 wind detections preferentially toward moderate-to-high accretors (>~10^{-8.5}~Msun/yr), whereas lower accretors exhibit only [OI] and [NeII] winds. Together, these results indicate that atomic jets and atomic+molecular winds, consistent with an MHD disk-wind origin, dominate during early, actively accreting disk phases, while at lower accretion rates, jets weaken and winds become predominantly atomic.
