How does a stellar nebula become a star
WebStar formation begins in relatively small molecular clouds called dense cores. Each dense core is initially in balance between self-gravity, which tends to compress the object, and … WebThe Cat's Eye Nebula, a planetary nebula formed by the death of a star with about the same mass as the Sun Stars of roughly 0.5–10 solar masses become red giants, which are large non-main-sequence stars of stellar classification K or M. Red giants lie along the right edge of the Hertzsprung–Russell diagram due to their red color and large ...
