- Calculate the distance of a star if the stellar spectrum indicates and absolute magnitude of -10 and the star has an apparent magnitude of 5.0 as seen from earthQ3.2 The supergiant star has a surface temperature of about 2900 K and emits a power of approximately 4 x 1030 W. Assuming that is a perfect emitter and spherical, find its radius. (hint: Area of the sphere is A = 4πr²)A star with a trigonometric parallax of .02 arcseconds has a distance of O2.0 light years. 50 pc. 4 kpc. 20 pc. O need more information (magnitudes)
