Cepheid Variable Star RS Puppis | Hubble’s Inside The Image | NASA Goddard FriendsofNASA.org: The Hubble Space Telescope has taken over 1.5 million observations over the years. One of them is the incredible image of RS Puppis. RS Puppis is a remarkable and highly luminous Cepheid variable star located in the constellation Puppis, known for its regular pulsations and dramatic changes in brightness. In this video, Dr. Padi Boyd explains this breathtaking image and how important Hubble is to explor

SOLVED:The Hubble Space Telescope has been used to study Cepheid variables in the galaxy M100. Assume the period-luminosity relation to be parameterized by [see Eq. (1.35)] Mv=-2.76 logP-1.4 with the period P expressed in days. What is the distance to M100 indicated by an observed Cepheid having a period of 51 days and average apparent visual magnitude of 24.9? In estimating the distance, assume that interstellar absorption between us and M100 has dimmed the Cepheid light by 0.15 magnitudes.

SOLVED:Go to the Goddard Multimedia website and view the animation of a Cepheid variable star in a spiral galaxy (http://svs .gsfc.nasa.gov/goto?10145). Explain how astronomers use data like these to estimate the distance to the galaxy. What is actually observed, what is assumed, and what is calculated? (Review the discussion in Chapter 16 as needed.)
