SUMMARY

The discussion centers on calculating the absolute magnitude of a star using its parallax angle and apparent magnitude. A star with a parallax angle of π = 10 milliarcseconds and an apparent magnitude of V = 10.2 is analyzed. The formula M = V - 5 log d - 5 + A is referenced, where d is derived from the parallax angle using the equation d = 1/p. The user expresses confusion regarding the distance calculation, which is consistently less than the Sun's distance.

PREREQUISITES
  • Understanding of stellar parallax and its measurement
  • Familiarity with the concept of apparent and absolute magnitude
  • Knowledge of logarithmic calculations in astronomy
  • Basic grasp of distance measurement in parsecs
NEXT STEPS
  • Study the relationship between parallax angle and distance in parsecs
  • Learn how to apply the absolute magnitude formula in practical scenarios
  • Explore the significance of apparent magnitude in stellar classification
  • Investigate common errors in distance calculations in astrophysics
USEFUL FOR

Astronomy students, astrophysics enthusiasts, and anyone interested in stellar measurements and calculations.

Can anyone help me get my head around this one?
A star with a parallax angle of pi = 10 millisecs and has apparent magnitude of V= 10.2
How can I determine absolute magnitude:
I have the formula M=v -5logd -5 +A which can be ignored.
d=1/pi but I am always determining d which is less than that of the sun's distance!
Thanks Red

10 m'' = .010" , d=\frac{1}{p''}, where d is the distance in parsecs. Solve for d. This should probably be in the homework section.
