The parallax angle for the red supergiant star betelgeuse has been measured using hipparcos to be 4.51 ± 0.80 mas (milliarcseconds). (g. m. harper et al 2017, aj, 154,11), a. find the distance to betelgeuse in units parsecs including uncertainty (which will be asymmetric, so you need to compute + and-uncertainties b. convert the optimal distance you computed in parsecs in part (a) into light-years; c. determine the distance modulus for betelgeuse (you may ignore uncertainty). separately) and round to the right number of significant figures. au. keep the correct number of significant figures. using clear english prose, explain why result makes sense (i certainly hope it d. betelgeuse has a mean v magnitude of m-0.45. what is its mean luminosity in solar luminosities? again, ignore uncertainty for now. hint: the sun's absolute vluminosity is~4.83
