Mesons named with the letter "f" are scalar mesons (as opposed to a pseudo-scalar meson), and mesons named with the letter "a" are axial-vector mesons (as opposed to an ordinary vector meson) a.k.a. an isoscalar vector meson, while the letters "b" and "h" refer to axial-vector mesons with positive parity, negative C-parity, and quantum numbers I G of 1 + and 0 − respectively.
HD 22663 (y Eridani) is a candidate astrometric binary [6] star system in the equatorial constellation of Eridanus. It is visible to the naked eye with an apparent visual magnitude of 4.57. [ 2 ] Based upon an annual parallax shift of 14.2 mas , [ 1 ] it is located around 230 light years from the Sun .

The primary is an orange-hued giant star of magnitude 4.9 and the secondary is of magnitude 8. 40 Eridani is a triple star system consisting of an orange main-sequence star, a white dwarf, and a red dwarf. The orange main-sequence star is the ...
HD 17925 is a variable star in the equatorial constellation of Eridanus.It has the Gould designation 32 G. Eridani and the variable star designation EP Eri. The star has a yellow-orange hue and is dimly visible to the naked eye in good seeing conditions with an apparent visual magnitude that varies from 6.03 down to 6.08. [16]
In the southern-sky catalog Uranometria Argentina, 82 G. Eridani (often abbreviated to 82 Eridani) [9] is the 82nd star listed in the constellation Eridanus. [10] The Argentina catalog, compiled by the 19th-century astronomer Benjamin Gould, is a southern celestial hemisphere analog of the more famous Flamsteed catalog, and uses a similar numbering scheme. 82 G. Eridani, like other stars near ...
17 Eridani is a single [10] star in the equatorial constellation of Eridanus. It has the Bayer designation v Eridani (not to be confused with ν (nu) Eri), while 17 Eridani is the Flamsteed designation. This object is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 4.74. [2]
