F-type main-sequence star

An F-type main-sequence star is a <a href="/facts/Main_sequence/DJ3Wq8kd">main-sequence</a>, <a href="/facts/Hydrogen/BoYHjl0J">hydrogen</a>-fusing <a href="/facts/Star/euBFuo07">star</a> of <a href="/facts/Spectral_classification/dYrIuK9H">spectral type</a> F. Such stars will generally have a <a href="/facts/Luminosity_class/dYrIuK9H">luminosity class</a> of V. They have from around 1.1 to 1.6 times the <a href="/facts/Solar_mass/j6Auhku8">mass</a> of the <a href="/facts/Sun/CadPCVHh">Sun</a> and <a href="/facts/Effective_temperature/RY30DaSY">surface temperatures</a> between about 6,000 and 7,200 <a href="/facts/Kelvin/E3trzC4C">K</a>. This temperature range gives the F-type stars a whitish hue when observed through the atmosphere.
Because a main-sequence star is referred to as a dwarf star, this class of star may also be termed a yellow-white dwarf (not to be confused with <a href="/facts/White_dwarf/gIYlTtrC">white dwarfs</a>, remnant stars that are a possible final stage of <a href="/facts/Stellar_evolution/Qa4vAGmn">stellar evolution</a>). Notable examples include <a href="/facts/Procyon_A/43Nou3on">Procyon A</a>, <a href="/facts/Gamma_Virginis/TWMaHpG3">Gamma Virginis</a> A and B, and <a href="/facts/Tabby%2527s_Star/AgbWCgam">Tabby's Star</a>.
