Textbook Question
Chapter 2, Problem 37EAP
Cultural Constellations. Many cultures have created their own sets of constellations that differ from those used officially in astronomical research. Learn about the constellations of a par-ticular culture of interest to you. How do the pattern of your chosen constellation(s) relate to the official constellations listed in Appendix H? Which set of patterns makes more sense to you personally?

Review Conceptual Example 3 for information pertinent to this problem. When we look at a particular star, we are seeing it as it was 307 years ago. How far away from us (in meters) is the star? Take a year to be 365.25 days.
On Earth, the parallax angle measured for the star Procyon is 0.29 arcseconds. If you were to measure Procyon's parallax angle from Venus, what would the parallax angle be? (Note: Earth's orbital radius is larger than Venus's orbital
radius.)
A. more than 0.29 arcseconds
O B. 0.29 arcseconds
O C. less than 0.29 arcseconds
D. zero arcseconds (no parallax)

- 1. A distant galaxy has an apparent magnitude of 10 and is 4,000 kpc away. What is its absolute magnitude? (Round your answer to at least one decimal place.) The difference in absolute magnitude between two objects viewed from the same distance is related to their fluxes by the flux-magnitude relation. FA/FB= 2.51(MB − MA) 2. How does the absolute magnitude of this galaxy compare to the Milky Way (M = −21)?arrow_forwardConsidering absolute magnitude M, apparent magnitude m, and distance d. Compute the unknown for each of these stars: a. m = +1.6mag, d = 4.3pc. What is M? b. M = -14.3 mag, m = 10.9 mag. What is d? c. m = -5.6mag, d = 88pc. What is M? d. M = 0.9mag, d = 220pc. What is m?arrow_forwardI 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_forward
- Problem 5. Imagine that you observe a star field twice, with a six-month gap between your observations, and that you see the two sets of stars shown below. Which do you think is closest to the observer? Figure 1: Schematic of image of stars A,B, and P taken six months apart. Problem 6. Suppose the angular separation between stars A and B is 0.5 arcseconds. How far would you estimate star P to lie from the observer?arrow_forward1. Planet A has an orbital period of 12 years and radius that is 0.033 times the radius of the star. Calculate the fractional dip of the star brightness in the case that planet A is transiting. Give the answer as a number. Quote the formula you use and explain any assumptions you have to make. 2. Planet B has an orbital period of 1 year and is located closer to its star than planet A. You succeed in detecting planet B with the radial velocity technique as well! From this measurement you calculate a minimum mass of planet B to be 75% that of the Earth. (a) Since you detect the planet with both transit method and radial velocity method, what do you know about the inclination of the planetary system? (b) Given this inclination, estimate the true mass of planet B (in units of Earth mass). You do not need to do a detailed calculation, just explain the argument. 3. You also measure the radius of planet B to be the same as Earth, one Earth radius. (a) How does the density of planet B compare…arrow_forwardStar X has an apparent magnitude of 0.03 and an absolute magnitude of 0.6. If it were moved to be twice as close to Earth as it is now, which of the following would occur? A. apparent magnitude number would decrease O B. absolute magnitude number would increase C. absolute magnitude number would decrease O D. apparent magnitude number would stay the same E. apparent magnitude number would increasearrow_forward
- 1, 2, 3arrow_forwardWhich of the following statements about stellar parallax is true? A. We observe all stars to exhibit at least a slight amount of parallax. B. Stellar parallax was first observed by ancient Greek astronomers. O C. The amount of parallax we see depends on how fast a star is moving relative to us. D. It takes at least 10 years of observation to measure a star's parallax. OE. The closer a star is to us, the more parallax it exhibits.arrow_forwardThe distance light travels in one second(one light-second) is about 1.86×10⁵ mi. Saturn is about 475 light-seconds from the sun. About how many miles from the sun is Saturn?arrow_forward
- I am trying to calculate the gravitational mass (in solar masses) I have the formula M= V^2 R / G (4.31 x 10^-6) The paperwork says our numbers should be big but I am coming up with .002 etc. What am I doing wrong?arrow_forwardStellar parallax is used as a tool to determine distances to stars. Describe how stellar parallax works. Also discuss the limiting factors in its use and the maximum distance that can be accurately measured using this technique. Do you believe this concept is unique to astronomy or used in other technical disciplines? Provide examples.arrow_forwardYou are standing at Earth's North Pole. It is dark, and the stars are out. What is an accurate description of where you need to look in order to find Polaris (the North Star)? Select one: a. straight overhead b. directly on the horizon c. about halfway up from the horizon to the zenith d. the North Star is not visible from this locationarrow_forward
