Difference between Binary star and Main sequence

Binary star vs. Main sequence

A binary star is a star system consisting of two stars orbiting around their common barycenter. In astronomy, the main sequence is a continuous and distinctive band of stars that appear on plots of stellar color versus brightness.

Similarities between Binary star and Main sequence

Binary star and Main sequence have 23 things in common (in Unionpedia): Absolute magnitude, Apparent magnitude, Binary star, Black hole, CNO cycle, Luminosity, Mass, Molecular cloud, Monthly Notices of the Royal Astronomical Society, Nuclear fusion, Parallax, Protostar, Red dwarf, Sirius, Spectral line, Star, Stellar classification, Stellar evolution, Sun, Supernova, Variable star, White dwarf, 61 Cygni.

Absolute magnitude

Absolute magnitude is a measure of the luminosity of a celestial object, on a logarithmic astronomical magnitude scale.

Black hole

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.

CNO cycle

The CNO cycle (for carbon–nitrogen–oxygen) is one of the two known sets of fusion reactions by which stars convert hydrogen to helium, the other being the proton–proton chain reaction.

Molecular cloud

A molecular cloud, sometimes called a stellar nursery (if star formation is occurring within), is a type of interstellar cloud, the density and size of which permit the formation of molecules, most commonly molecular hydrogen (H2).

Nuclear fusion

In nuclear physics, nuclear fusion is a reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons or protons).

Spectral line

A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.
