SOLVED: Suppose you are observing Cepheids in a nearby galaxy. Youobserve one Cepheid with a period of 10 days between peaks inbrightness and another with a period of 30 days. Estimate theluminosity of each star. Explain how you arrived at yourestimate.

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: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.)

Zooming in on The Trifid Nebula & Cepheid Variable Stars | ESO Support FriendsofNASA.org | This zoom video takes the viewer deep into the spectacular central regions of the Milky Way. 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!

The spiral galaxy NGC 3370 hosts two critical standard candles in extragalactic astronomy: Cepheid variable stars and Type Ia supernovae. The intrinsic luminosity of Cepheid variables is determined via the well-established period–luminosity relation, wherein pulsation period correlates directly with absolute magnitude. Type Ia supernovae exhibit a standardized peak luminosity due to their origin in carbon–oxygen white dwarf detonations near the Chandrasekhar limit. By comparing observed apparent
