Examples of eclipsing binaries are Epsilon Aurigae (Almaaz), VV Cephei, and V766 Centauri (HR 5171). Angular diameter measurements can be inconsistent because the boundary of the very tenuous atmosphere ( opacity ) differs depending on the wavelength of light in which the star is observed.
AE Aurigae is a blue O-type main sequence star with a mean apparent magnitude of +6.0, making it faintly visible to the naked eye under very good observing conditions. It was discovered to be a variable star by Daniel Walter Morehouse , in 1923, and received its variable star designation in 1924. [ 8 ]
Psi 9 Aurigae, Latinised from ψ 9 Aurigae, is a star in the northern constellation of Auriga. It is dimly visible to the naked eye with an apparent visual magnitude of 5.75. [ 2 ] Based upon an annual parallax shift of 2.59 mas , [ 1 ] the distance to this star is approximately 1,300 light-years (400 parsecs ).
Psi 1 Aurigae (ψ 1 Aur, ψ 1 Aurigae) is a star in the northern constellation of Auriga. It is faintly visible to the naked eye with an apparent visual magnitude of 4.91. [ 2 ] Based upon a measured annual parallax shift of 0.44 mas , [ 1 ] it is approximately 7,500 light-years (2,300 parsecs ) distant from the Earth.
16 Lyncis is a star in the constellation Lynx. It is positioned next to the western constellation border with Auriga , and is also known as Psi 10 Aurigae , which is Latinized from ψ 10 Auriga. The star has a white hue and is visible to the naked eye with an apparent visual magnitude of 4.90. [ 2 ]
