预览提示词
Create a horizontal editorial diagram of the stellar life cycle on a deep dark starfield. Use a single branching flow that reads left to right. Begin with a glowing molecular cloud labeled "Nebula (collapsing gas and dust)", then "Protostar", then a central "Main-Sequence Star (hydrogen fusion)" node. From the main sequence, split into two clearly labeled mass paths. The lower, low-mass path shows "Sun-like (about 1 solar mass)" leading to "Red Giant", then "Planetary Nebula", ending at "White Dwarf". The upper, high-mass path shows "Massive (more than 8 solar masses)" leading to "Red Supergiant", then "Supernova (Type II)", branching to "Neutron Star" or "Black Hole". Connect stages with luminous tapered arrows and short timescale captions such as "approximately 10 billion years" and "a few million years". Add a small inset Hertzsprung-Russell diagram with axes "Luminosity" and "Temperature (K, reversed)", showing the main sequence band, giant branch, and white dwarf region. Keep it clean and publication-quality with tidy spacing, legible white labels, and a balanced layout.
