Following the detailed analysis of the H${}_2$ molecule in an intermediate magnetic field $B\lesssim 5\times {10}^8$ G performed in Alijah et al, JQSRT 233, 78 (2019) [1] a similar compact, few-parametric, physically adequate, 3-term variational trial function is used to study the energy of the ground state ${}^3{\Pi }_u$ of the hydrogen molecule ${\mathrm{H}}_2$in an astronomically strong magnetic field $\mathbf{B}$ in the range $5\times {10}^{10}\mathrm{G}\le B\le {10}^{13}$ G. The nuclei (protons) are assumed to be infinitely heavy (Born-Oppenheimer approximation of zeroth order) and situated along the magnetic field line (parallel configuration).

分子 ${\mathrm{H}}_2$ 再次在强磁场中

以下详细分析H${}_2$ 分子在中间磁场中 $乙\lesssim 5\times {10}^8$ 的G Alijah等，进行JQSRT 233，78（2019）[1]类似的紧凑，几个参数，物理上足够，3-术语变试探函数是用来研究基态的能量${}^3{\Pi }_{ü}$ 氢分子的 ${\mathrm{H}}_2$在天文强磁场中 $\mathbf{乙}$ 范围中 $5\times {10}^{10}\mathrm{G}\le 乙\le {10}^{13}$ G.假定核（质子）是无限重的（零级的伯恩-奥本海默近似），并且沿着磁场线（平行构型）放置。
