A cepheid star is located at a distance of 24.8kpc from the Earth and has an apparent visual magnitude of 13.3. Determine its pulsation period in days.Consider the following expression of the Leavitt relationMy -2.78 log Pdays - 1.35,where My is the absolute visual magnitude and Pdays the pulsation period in days to 2 decimal places.

What is the advantage of measuring a parallax distance to a star as compared to our other distance measuring methods?
The nearest neutron star (a collated star made primarily of neutrons) is about 3.00 1018 m away from Earth. Given that the Milky Way galaxy (Fig. P1.81) is roughly a disk of diameter 1021 m and thickness 1019 m, estimate the number of neutron stars in the Milky Way to the nearest order of magnitude. Figure P1.81
What is the defining difference between a brown dwarf and a true star?
What is the disadvantage of the parallax method, especially for studying distant parts of the Galaxy?
Which of the following can you determine about a star without knowing its distance, and which can you not determine: radial velocity, temperature, apparent brightness, or luminosity? Explain.
Verify that if two stars have a difference of five magnitudes, this corresponds to a factor of 100 in the ratio (b2b1) ; that 2.5 magnitudes corresponds to a factor of 10; and that 0.75 magnitudes corresponds to a factor of 2.
Why do you think astronomers have suggested three different spectral types (L, T, and Y) for the brown dwarfs instead of M? Why was one not enough?
As seen from Earth, the Sun has an apparent magnitude of about 26.7 . What is the apparent magnitude of the Sun as seen from Saturn, about 10 AU away? (Remember that one AU is the distance from Earth to the Sun and that the brightness decreases as the inverse square of the distance.) Would the Sun still be the brightest star in the sky?
What would be the Schwarzschild radius, in light years, if our Milky Way galaxy of 100 billion stars collapsed into a black hole? Compare this to our distance from the center, about 13,000 light years.
The best parallaxes obtained with Hipparcos have an accuracy of 0.001 arcsec. If you want to measure the distance to a star with an accuracy of 10%, its parallax must be 10 times larger than the typical error. How far away can you obtain a distance that is accurate to 10% with Hipparcos data? The disk of our Galaxy is 100,000 light-years in diameter. What fraction of the diameter of the Galaxy’s disk is the distance for which we can measure accurate parallaxes?
Look at Figure 1-9. Would you say that the distribution of stars is uniform in this field of view, 17 ly across? Compare with Figure 1-10, 1700 ly across. Now look at Figure 1-12; would you say that the distribution of galaxies is uniform in this field of view, 17 million ly across? Compare with Figure 1-13, 1.7 billion ly across.
