Morphology
The phrase is compositionally built from 'red' (color) + 'dwarf' (small) + 'star' (celestial body), so a learner who knows the constituents can infer it refers to a small, reddish star. Although the term has additional technical properties (low mass, cool, long-lived), its core denotation is directly derived from the parts and follows common cross-linguistic modifiers, making it immediately comprehensible to B1 learners.
Etymology
Red dwarf star comes from a simple picture: a very small star that gives a faint red light and so seems like a dwarf among the other stars. That's why the name means a 'small', 'cool' star that can shine for a very long time.
