Prompt: In a distant galaxy

Generated text:
In a distant galaxy , a star of mass $M$ is observed to have a luminosity $L$. The star is observed to have an absolute magnitude of $M_\star = 25$. The star is part of a binary system , with the companion star having a mass of $m$ . The orbital inclination of the binary system is $i$. The orbital period of the binary system is $P$ years . The observed luminosity of the binary system is $L_\star$. The observed magnitude of the binary system is $m_\star$. The observed magnitude of the companion star is $m_\text{comp}$. The observed magnitude of the star alone is $m_\star$.
