论文摘要
太阳风在远离太阳时经历了明显的加热。负责这种加热的确切机制尚不清楚。使用Parker太阳能探测任务的第一个围栏中的数据，我们检查了通过鉴定的磁相干结构中发生的质子和电子加热的特性，这些结构通过增量的部分方差（PVI）方法确定。从统计上讲，磁场中具有强梯度的空间区域，$ pvi \ geq 1 $，与强大的质子相关，但仅略有升高的电子温度。我们的分析表明，非线性湍流级联反应促进的新生太阳风环境中的加热机制优先将质子加热到电子上。
The solar wind undergoes significant heating as it propagates away from the Sun; the exact mechanisms responsible for this heating remain unclear. Using data from the first perihelion of the Parker Solar Probe mission, we examine the properties of proton and electron heating occurring within magnetic coherent structures identified by means of the Partial Variance of Increments (PVI) method. Statistically, regions of space with strong gradients in the magnetic field, $PVI \geq 1$, are associated with strongly enhanced proton but only slightly elevated electron temperatures. Our analysis indicates a heating mechanism in the nascent solar wind environment facilitated by a nonlinear turbulent cascade that preferentially heats protons over electrons.
