  The ordinary convention is to write apparent magnitudes with a lower-case letter m, and absolute magnitudes with an upper-case M. One can derive a formula which connects the apparent and absolute magnitudes of a star, using the inverse square ... and comparing the apparent brightness of the two objects. In this case, the quantities actually ...

• A Test of Possible NICMOS Non-linearity

  High flux regime: We compared the observed flux in the high count regime by comparing apparent magnitudes previously published by Stephens et al (2000) of stars, observed with both NICMOS (NIC2) in F110W and F160W and ground-based near-IR detectors in J and H-bands. The ground-based detectors are operated in the sky-dominated regime due to the

  two stars, given their apparent magnitudes. Consider the following: Let us compare the brightness of two stars with apparent magnitudes of 4.6 and 2.2. First of all, you need to recognise that the smaller magnitude is brighter than the larger magnitude star. The brighter star has 2.512($ .&'!)=2.512!.$=9.1 times the intensity of the dimmer star ...

  3 This also works for absolute magnitudes The relationship between magnitude and flux applies for absolute and apparent magnitudes. For example, we can solve the following problem: What would is the V band magnitude of a galaxy that is composed entirely of sun-like stars? The mass of a galaxy is ∼ 1012 solar masses.3 If we assume that the entire

  The apparent magnitude, m, of a star in the night sky is a measure of its brightness which depends on the intensity of the light received from the star. Consider two stars X and Y of apparent magnitudes m X and m Y which give received intensities I X and I Y. Every difference of 5 magnitudes corresponds to 100 times more light intensity from X

The di erence is that apparent magnitudes are to ux as absolute magnitudes are to luminosities, thus it follows that: L L ref = 100:4( M ref) (3) The Sun has an absolute visual magnitude of M V = 4:8.

Finally, the basic magnitude system used here is one based on the apparent brightness of stars. That is, how they appear in the sky to the observer.
