Cepheid Variable Star RS Puppis 24/03/2018 • The super star is ten times more massive than our Sun and 200 times larger. • Its average intrinsic brightness is 15,000 times greater than our Sun's luminosity. • Distance to RS Puppis has been narrowed down to 6,500 light-years (with a margin of error of only one percent). This movie shows the reflection nebula around the Cepheid variable RS Puppis at seven equally spaced intervals during its 41.4-day pulsation period. Each time RS Puppis reaches ma

A Cepheid variable star is a star whose brightness alternately increases and decreases. The most easily visible such star is Delta Cephei, for which the interval between times of maximum brightness is 5.4 days. The average brightness of this star is 4.0 and its brightness changes by ±O.35. In view of these data, the brightness of Delta Cephei at time t, where t is measured in days, has been modeled by the function B(t) = 4.0 0.35 sin((2 πt)/(5.4)) (a) Find the rate of change of the brightness
