Lambda Doradus

Lambda Doradus (Lambda Dor), Latinized from λ Doradus, is a solitary yellow hued star located in the southern constellation Dorado. It has an apparent magnitude of 5.13, making it faintly visible to the naked eye if viewed under ideal conditions. Parallax measurements place the star at a distance of 551 light years, and it is currently receding with a heliocentric radial velocity of $$.

Lambda Dor has a stellar classification of either G6 or G8 III, depending on the source. Nevertheless, both indicate that it is a red giant, and it is currently on the red giant branch fusing hydrogen in a shell outside a helium core. At present it has 3.82 times the mass of the Sun and at an age of 258 million years, it has expanded to a radius of. It radiates at over 250 times the luminosity of the Sun from its photosphere at an effective temperature of $$. Lambda Dor is slightly metal deficient, with an iron abundance 12% below solar levels. It currently spins with a projected rotational velocity of $$.
