Absolute magnitude of stars from apparent magnitude and distance¶

Absolute magnitude can be calculated using apparent magnitude and distance to the object.

Wikipedia, second formula.

absolute_magnitude¶

absolute_magnitude of the object.

Symbol:: M
Latex:: \(M\)
Dimension:: dimensionless

apparent_magnitude¶

apparent_magnitude of the object.

Symbol:: m
Latex:: \(m\)
Dimension:: dimensionless

distance¶

euclidean_distance to the object.

Symbol:: d
Latex:: \(d\)
Dimension:: length

distance_constant¶

Constant equal to \(2.063 \cdot 10^6\) astronomical units.

Symbol:: d_0
Latex:: \(d_0\)
Dimension:: length

law¶

M = m - 5 * log(d / d_0, 10)

Latex:: \[M = m - 5 \log_{10} \left( \frac{d}{d_0} \right)\]
