The distance to Proxima Centauri using the parallax method (p = 0.77) results in a measurement of about 4 light years. The standard candle method
The distance to Proxima Centauri using the parallax method (p = 0.77) results in a measurement of about 4 light years. The standard candle method (apparent magnitude = 11.05; absolute magnitude = 15.49)also results in a measurement of about 4 light years. Show the computations using the parallax equation and the standard candle equation. (For the SC equation use the x2button above the posting box.)
Parallax Method
If the parallax angle, p, is measured in arcseconds (arcsec), then the distance to the star, d in parsecs (pc) is given by:
d = 1/p
Candle Formula
d = 10(m - M + 5)/5
Add some brief explanation for each step (show each step, starting with the formula)
Then, short narrative explanation:From a scientific and an inductive reasoning point of view why is getting about the same answer with two different methods viewed as extremely significant?
