Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

An astronomer is investigating a faint star that has recently been discovered in very sensitive surveys of the sky. The star has a magnitude of 16. How much less bright is it than Antares, a star with magnitude roughly equal to 1?
The lowest mass for a true star is 1/12 the mass of the Sun. What is the luminosity of such a star based upon the mass-luminosity relationship?
How does luminosity differ from apparent brightness ?
Two stars – A and B, of luminosities 0.5 and 4.5 times the luminosity of the Sun, respectively – are observed on Earth to have the same apparent brightness. Which star is more distant, and how much farther away is it than the other? [Hint: The brightness of a star is inversely proportional to the square of its distance; Week 6 slide 15]
2. Of the 2 stars: a low-mass star or high-mass star: a. Which star has more fuel? - b. Which star lasts less time? -
The satellite Hipparcos was launched in 1989 to measure very accurate parallax angles of stars; it has provided the most accurate parallax measurements ever obtained. The smallest parallax angle it can measure is 0.002". How far away is the most distant star to which Hipparcos can measure the distance?
The luminosity of a star is 6.6 x 1031 W and the peak wavelength in its spectrum is 4.6 x 10-7 m. Calculate the surface area of that star. Round off the answer to 2 decimal places with scientific representation.
"51 Pegasi" is the name of the first normal star (besides the Sun) around which a planet was discovered. It is in the constellation Pegasus the horse. Its parallax is measured to be 0.064 arcsec. a.

In a laboratory, the Balmer-beta spectral line of hydrogen has a wavelength of 486.1 nm . If the line appears in a star’s spectrum at 485.8 nm , what is the star’s radial velocity? Is it approaching or receding? Is this a blueshift or a redshift?
The spectrum of the Sun has hundreds of strong lines of nonionized iron but only a few, very weak lines of helium. A star of spectral type B has very strong lines of helium but very weak iron lines. Do these differences mean that the Sun contains more iron and less helium than the B star? Explain.
One method to measure the diameter of a star is to use an object like the Moon or a planet to block out its light and to measure the time it takes to cover up the object. Why is this method used more often with the Moon rather than the planets, even though there are more planets?
