Which of the following could reasonably be Capella’s absolute magnitude? +4.05 –10.5 Use the spectral types and the HR diagram to estimate their absolute magnitudes. The difference between the apparent and absolute magnitudes is called the distance modulus. Calculate the distance modulus (m-M) for these six stars.

Capella A Mass: 2.7 x Sun Capella B Mass: 2.5 x Sun. Capella A Luminosity: 80 x Sun Capella B Luminosity: 75 x Sun. Capella A Diameter: 10.4 million miles (16.8 million km) - 12 x Sun Capella B Diameter: 7.8 million miles (12.6 million km) - 9 x Earth The absolute magnitude is the magnitude the stars would have if viewed from a distance of 10 parsecs or some 32.6 light years. Obviously, Deneb is intrinsically very bright to make this list from its greater distance. Rigel, of nearly the same absolute magnitude, but closer, stands even higher in the list. Capella Ab Apparent and Absolute Magnitudes Capella Ab has an apparent magnitude of 0.08 which is how bright we see the star from Earth.

Capella's absolute magnitude is 0.4 and Altair's absolute magnitude is 2.3. Which is brighter? Keywords: Stars, apparent magnitude, absolute magnitude, empirical formula, Hertzsprung-Russell diagram 1.

ABSOLUTE MAGNITUDE Absolute magnitude is a measure of the inherent brightness of a celestial object. This scale is defined as the apparent magnitude a star would have if it were seen from a standard distance of 32.6 light-years (10 parsecs).The lower the number, the brighter the object. 2014-09-15 Composer Harry Lightfoot rounds out the featured Volturnus tracks with "Absolute Magnitude," a glorious melting together of piano, synths, vocal and choir in Antares, also called Alpha Scorpii, red, semiregular variable star, with apparent visual magnitude about 1.1, the brightest star in the zodiacal constellation Scorpius and one of the largest known stars, having several hundred times the diameter of the Sun and 10,000 times the Sun’s luminosity.

The red dot in the diagram below shows where Capella is situated in the Hertzsprung–Russell diagram.

0.13v. Absolute magnitude, M, is the magnitude a star would have if located at a certain Capella. Alpha Aur. 0.08 -0.5.

The star is the third brightest in the northern celestial hemisphere, after Arcturus and Vega, and the closest first-magnitude star to the North Pole, with an apparent magnitude of 0.91. Although appearing as a single star in the night sky, Capella is actually a system composed of four stars grouped in two binary pairs.
