我们给出了用菲尼克斯程序计算的一组模式大气和合成光谱的结果。模型涵盖了有效温度2700K<；=T_Jeff<；=10000K，重力(-0.5<；=log(G)<；=5.5)和金属度(-4.0<；=[Z/H]<；=+0.5)。此外，还考虑了不同金属丰度下α元素的变化。这些模型是用一组同类的输入数据来计算的，以便允许模型之间的直接相对比较。例如，所有模型都使用L/H_p=2.0的混合长度。我们为所有型号提供了从紫外光到红外光的0.2纳米分辨率的合成光谱。我们给出了输入物理的简要概述，并显示了说明性的结果。所有合成光谱均可通过ftp：ftp.hs.uni-hamburg.de/pub/outgoing/phoenix/GAIA获取。
We present the results of a set of model atmospheres and synthetic spectra computed with the PHOENIX code. The models cover a range of effective temperatures 2700 K <= T_eff <= 10 000 K, gravities (-0.5 <= log(g)<= 5.5) and metalicities (-4.0 <= [Z/H] <= +0.5). In addition, variations of alpha elements are considered for each metalicity. The models are computed with a homogeneous set of input data in order to allow for direct relative comparison between the models. For example, all models use a mixing length of l/H_p = 2.0. We provide synthetic spectra with a resolution of 0.2 nm from the UV to the infrared for all models. We give a brief overview of the input physics and show illustrative results. All synthetic spectra are available via ftp: ftp.hs.uni-hamburg.de/pub/outgoing/phoenix/GAIA
