chart showing luminosity relative to the sun vs surface temperature (k) with star groups: supergiants, giants, main sequence, white dwarfs, and labeled stars like spica, rigel, deneb, betelgeuse, polaris, aldebaran, pollux, sirius, alpha centauri, sun, 40 eridani b, procyon b, barnard’s star, proxima centauri

Explanation:

Our Sun is currently in the main sequence stage, with a luminosity of ~1 (relative to the Sun) and a surface temperature around 5800 K. Stars with similar initial mass evolve from main sequence to giant/white dwarf stages. White dwarfs are the final stage for Sun-like stars, and 40 Eridani B is a white dwarf, meaning it was once a main sequence star with mass and luminosity similar to our Sun.

Answer:

40 Eridani B
