![Power density values for transient accreting binaries: cataclysmic variables, neutron stars, and black holes, plotted with control datasets, life on Earth on the left of the plot (prokaryotes, eukaryotes, multicellular), young stellar objects (YSOs, yellow), and persistently accreting white dwarfs (nova-like, pink empty circles), and supermassive black holes (magenta filled circles). Above the stability boundary line are explosive systems.-- [physics.gen-ph]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/11/Power.png?resize=1200%2C718&ssl=1)
