Angular distance

Angular distance or angular separation is the measure of the angle between the orientation of two straight lines, rays, or vectors in three-dimensional space, or the central angle subtended by the radii through two points on a sphere.

See Gamma Equulei and Angular distance

Ap and Bp stars

Ap and Bp stars are chemically peculiar stars (hence the "p") of spectral types A and B which show overabundances of some metals, such as strontium, chromium, or europium.

See Gamma Equulei and Ap and Bp stars

Apparent magnitude

Apparent magnitude is a measure of the brightness of a star or other astronomical object.

See Gamma Equulei and Apparent magnitude

Asteroseismology

Asteroseismology is the study of oscillations in stars.

See Gamma Equulei and Asteroseismology

Chemically peculiar star

In astrophysics, chemically peculiar stars (CP stars) are stars with distinctly unusual metal abundances, at least in their surface layers.

See Gamma Equulei and Chemically peculiar star

Chromium

Chromium is a chemical element; it has symbol Cr and atomic number 24.

See Gamma Equulei and Chromium

Constellation

A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object.

See Gamma Equulei and Constellation

Double star

In observational astronomy, a double star or visual double is a pair of stars that appear close to each other as viewed from Earth, especially with the aid of optical telescopes.

Equuleus

Equuleus is a faint constellation located just north of the celestial equator.

Europium

Europium is a chemical element; it has symbol Eu and atomic number 63.

Iron

Iron is a chemical element.

Latinisation of names

Latinisation (or Latinization) of names, also known as onomastic Latinisation, is the practice of rendering a non-Latin name in a modern Latin style.

Main sequence

In astronomy, the main sequence is a classification of stars which appear on plots of stellar color versus brightness as a continuous and distinctive band.

See Gamma Equulei and Main sequence

Minute and second of arc

A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol, is a unit of angular measurement equal to of one degree.

Monthly Notices of the Royal Astronomical Society

Monthly Notices of the Royal Astronomical Society (MNRAS) is a peer-reviewed scientific journal in astronomy, astrophysics and related fields.

Radial velocity

The radial velocity or line-of-sight velocity of a target with respect to an observer is the rate of change of the vector displacement between the two points.

See Gamma Equulei and Radial velocity

Rapidly oscillating Ap star

Rapidly oscillating Ap stars (roAp stars) are a subtype of the Ap star class that exhibit short-timescale rapid photometric or radial velocity variations. Gamma Equulei and Rapidly oscillating Ap star are Rapidly oscillating Ap stars.
