- Which of the following is least reasonable regarding the magnitude scale: Group of answer choices The numerical difference between a star's absolute and apparent magnitudes is a measure of the distance to the star. If the Sun were moved to a distance of 10 parsecs, its apparent magnitude would be about 4.8 and it would therefore not be visible to the naked eye. The fact that Sun's absolute magnitude of 4.8 is greater than the Sun's apparent magnitude of -27 implies that the Sun is a lot closer than 10 parsecs. Apparent magnitude measures a star's apparent brightness when viewed at the star's actual distance from the observer. A star's absolute magnitude is its apparent magnitude when viewed from a distance of 10 parsecs.Use the Luminosity Distance Formula. Find the distance to a star (L=2.2x1026 watts) whose apparent brightness at Earth is 2.0 x10-10 watt/m2. Formula: Absolute Brightness (AB) = Luminosity / 4π r2Which of the following WOULD NOT characterizes the type(s) of star we would find at g, m, n, o, and p on the Hertzsprung-Russel Diagram (Figure 4) a. are all smaller than q,i,h. b. fuse hydrogen into helium. c. are called, “the main sequence”. d. fuse He into heavier elements. e. get smaller towards the right side
- You measure a star to have a parallax angle of 0.04 arc-seconds. What fraction of a degree is this?Solve the following problem: Two stars, named A and B, each with a mass equal to the Sun's mass are in orbit around each other. If the distance between the two stars is 1.0 AU. What is the period of their orbit? Describe each step in solving the problem:What is the apparent magnitude of the sun as seen from Saturn about 10 AU away? Appear to magnitude of Saturn =
- What is the parallax of a star that is 150 pc from Earth?Calculate by how many times Betelgeuse is brighter than the Sun, if its parallax is 0.006 arcsec, and its apparent magnitude is m = +.5. Can you first use the parallax to calculate the distance and then use the magnitude-distance formula to find the absolute magnitude of Betelgeuse and finally, compare it to the absolute magnitude of the Sun which is -26,74 because other experts used other methods and the answer was not correct.If we view a star now, and then view it again 6 months later, our position will have changed by the diameter of the Earth's orbit around the sun. For nearby stars (within 100 light-years or so), the change in viewing location is sufficient to make the star appear to be in a slightly different location in the sky. Half of the angle from one location to the next is known as the parallax angle (see figure). Parallax can be used to measure the distance to the star. An approximate relationship is given by d = 3.26 p , where d is the distance in light-years, and p is the parallax measured in seconds of arc. Vega is a star that has a parallax angle of 0.13 second. How far is Vega from the sun? Note: Parallax is used not only to measure stellar distances. Our binocular vision actually provides the brain with a parallax angle that it uses to estimate distances to objects we see. (Round your answer to two decimal places.) light-years
