Concept explainers
Complete the table of apparent magnitude, absolute visual magnitude, distances, and parallaxes.
Answer to Problem 3P
Complete table is as follows-
7 | 7 | 10 | 0.1 |
11 | 1 | 1000 | 0.001 |
6 | -2 | 400 | 0.025 |
4 | -2.98 | 250 | 0.040 |
Explanation of Solution
Given:
Incomplete table
- | 7 | 10 | - |
11 | - | 1000 | - |
- | -2 | - | 0.025 |
4 | - | - | 0.040 |
Formula used:
Distance of star in parsec is calculated as
Absolute magnitude of the star is given as
Calculation:
Parallax of star is calculated as
Apparent magnitude of the star is calculated as
Parallax of star is calculated as
Absolute magnitude of the star is calculated as
Distance of star is calculated as
Apparent magnitude of the star is calculated as
Distance of star is calculated as
Apparent magnitude of the star is calculated as
Therefore the complete table is as follows
7 | 7 | 10 | 0.1 |
11 | 1 | 1000 | 0.001 |
6 | -2 | 400 | 0.025 |
4 | -2.98 | 250 | 0.040 |
Conclusion:
Complete table is as follows-
7 | 7 | 10 | 0.1 |
11 | 1 | 1000 | 0.001 |
6 | -2 | 400 | 0.025 |
4 | -2.98 | 250 | 0.040 |
