Let us imagine that the spectrum of a star is collected and we find the absorption line of Hydrogen-Alpha (the deepest absorption line of hydrogen in the visible part of the electromagnetic spectrum) to be observed at 656.5 nm instead of 656.3 nm as measured in a lab here on Earth. What is the velocity of this star in m/s? (Hint: speed of light is 3*10^8 m/s; leave the units off of your answer)

Using the center-of-mass equations or the Center of Mass Calculator (under Binary-Star Basics, above), you will investigate a specific binary-star system. Assume that Star 1 has
m1 = 3.2
solar masses, Star 2 has
m2 = 1.6
solar masses, and the total separation of the two (R) is 80 AU. (One AU is Earth's average distance from the Sun.)
(a)
What is the distance,
d1,
(in AU) from Star 1 to the center of mass?

- Do the previous problem again, this time using the information that the Sun is 150,000,000 km away. You will get a very large number of km as your answer. To get a better feeling for how the distances compare, try calculating the time it takes light at a speed of 299,338 km/s to travel from the Sun to Earth and from Alpha Centauri to Earth. For Alpha Centauri, figure out how long the trip will take in years as well as in seconds.arrow_forwardWhite Dwarf Size II.

- Suppose we find an Earth-like planet around one of our nearest stellar neighbors, Alpha Centauri (located only 4.4 light-years away). If we launched a "generation ship" at a constant speed of 1500.00 km/s from Earth with a group of people whose descendants will explore and colonize this planet, how many years before the generation ship reached Alpha Centauri? (Note there are 9.46 ××1012 km in a light-year and 31.6 million seconds in a year.arrow_forwardMost stars (Main sequence) generate light through the same mechanism. Because of this, there is an empirical relation between their mass, M, and their Luminosity, L.

- I attempted to answer this question and I'm not sure what I am doing wrong. My formula says A.S. = 206265 (separation/distance from observer) I know to convert to the same units, so I ended up with 80 Million Km being 8 x 10 ^ -6 LY Could you please explain each step especially for the part that I got wrong for both A and B?arrow_forwardThe telescope and CCD camera described in question 2 are scheduled to observe the star cluster M67 at 22:00 GMT on 02/03/2022. Using Stellarium, determine whether or not this is a good time to observe the cluster. Choose the answer below that best matches your conclusions. a. No - the cluster is not visible from London at this date and time. b. The cluster is visible but the full Moon is close by and so will interfere with the observations. c. The cluster is visible but is very close to the horizon and so will be difficult to observe. d. The cluster M67 is never visible in the sky from London so we should abandon any plans to observe it. e. Yes this is a good time to observe the cluster as it is well placed in the sky for viewing and the moon is not visible.arrow_forwardIn a binary star system, the average separation between the stars is 5 AU and their orbital period is 4 years.
