上下文太阳耀斑是日冕中的磁能突然释放的结果。这些能量的大部分用于加速带电粒子到高速。这些粒子沿着磁场运动，当密度足够高时，能量被耗散，主要是在太阳色球层中。模拟这一区域是困难的，因为辐射能量平衡是由强大的，光学厚光谱线。我们的目标是为社区提供耀斑环的真实模拟，重点是色球能量平衡的详细处理。这将使现有的和即将到来的观测与模拟合成观测值的详细比较，从而阐明复杂的相互作用在一个燃烧的色球。我们使用一维辐射流体动力学代码RADYN进行模拟的电子束注入在太阳日冕环的顶点的效果。产生了一个网格模型，改变了总能量输入、陡度和束能谱的低能截止。网格模型的完整模拟结果可在线获得。一些一般性质的模拟进行了讨论。
Context. Solar flares are the result of the sudden release of magnetic energy in the corona. Much of this energy goes into accelerating charged particles to high velocity. These particles travel along the magnetic field and the energy is dissipated when the density gets high enough, primarily in the solar chromosphere. Modelling this region is difficult because the radiation energy balance is dominated by strong, optically thick spectral lines.Aims. Our aim is to provide the community with realistic simulations of a flaring loop with an emphasis on the detailed treatment of the chromospheric energy balance. This will enable a detailed comparison of existing and upcoming observations with synthetic observables from the simulations, thereby elucidating the complex interactions in a flaring chromosphere.Methods. We used the 1D radiation hydrodynamics code RADYN to perform simulations of the effect of a beam of electrons injected at the apex of a solar coronal loop. A grid of models was produced, varying the total energy input, the steepness, and low-energy cutoff of the beam energy spectrum.Results. The full simulation results for a grid of models are made available online. Some general properties of the simulations are discussed.
