Third, the range in absolute magnitude of the RR Lyrae stars appears to be quite
restricted. Fourth, RR Lyrae stars, like Cepheids, have the virtue that they can be
easily identified from their light variations. For these reasons the absolute ...

Astronomy: A Physical Perspective
In order to compare intrinsic luminosities of stars, we define a system of absolute
magnitudes. The absolute magnitude of a star is that magnitude that it would
appear to have as viewed from a standard distance, d0. This standard distance is
...

Sky Catalogue 2000.0: Stars to
magnitude 8.0
is straightforward to show that if m is the apparent magnitude and M is the
absolute magnitude of a star, then m - M = Slogd - 5, where d is the distance in
parsecs. (Notice that when d is 10 parsecs, the right side of this equation
becomes zero ...

Physics for the IB Diploma: Standard and Higher Level
In order to be able to compare stars in this way, the concept of absolute
magnitude has been introduced. The absolute magnitude of a star is the
apparent magnitude that it would have IF it were observed from a distance of TO
parsecs.

Foundations of Astronomy
Calculating Absolute Magnitude If you know a star's apparent visual magnitude
and its distance, you can calculate its absolute visual magnitude. The magnitude
–distance formula that allows this calculation relates apparent visual magnitude ...
Michael Seeds, Dana Backman, 2012
The magnitude–distance formula relates the apparent magnitude m v , the
absolute magnitude M v , and the distance d in parsecs: mv M v 5 5 log10(d) If
you know any two of the parameters in this formula, you can easily calculate the
third.
