We have the following information: A star that is three times the size of our Sun is Violet in color, so the peak in its continuous spectrum is at 275 nm. Parallax tells us that it is at a distance of 123.4 pc (about 400 light years). Use this information for the following questions.
1.) How much energy is emitted per square meter? What is this stars luminosity?
2.) What is the apparent luminosity of this star?
