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.

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

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.

The final sequence closes in on the famous Trifid Nebula, as seen in an infrared image from the VISTA telescope at European Southern Observatory’s Paranal Observatory, including two Cepheid variables far beyond. A Cepheid variable is a type of star that pulsates radially, varying in both diameter and temperature, a

The spiral galaxy NGC 3370 is home to some of the most useful objects in astronomy: Cepheid variable stars and Type Ia supernovae. The brightness of a Cepheid variable star can be calculated from how quickly it pulsates, while Type Ia supernovae have a consistent brightness. Measuring how bright they appear from Earth, then, makes it possible to calculate how far away they are 📏 and how far away their host galaxies are!
