A-type main-sequence star

An A-type main-sequence star (A) or A dwarf star is a main-sequence (hydrogen burning) star of spectral type A and luminosity class (five).

See Epsilon Pyxidis and A-type main-sequence star

Am star

An Am star or metallic-line star is a type of chemically peculiar star of spectral type A whose spectrum has strong and often variable absorption lines of metals such as zinc, strontium, zirconium, and barium, and deficiencies of others, such as calcium and scandium.

See Epsilon Pyxidis and Am star

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 Epsilon Pyxidis and Angular distance

Apparent magnitude

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

See Epsilon Pyxidis and Apparent magnitude

Astronomical unit

The astronomical unit (symbol: au, or AU) is a unit of length defined to be exactly equal to.

See Epsilon Pyxidis and Astronomical unit

Binary star

A binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other.

See Epsilon Pyxidis and Binary star

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 Epsilon Pyxidis and Constellation

Effective temperature

The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation.

See Epsilon Pyxidis and Effective temperature

Epoch (astronomy)

In astronomy, an epoch or reference epoch is a moment in time used as a reference point for some time-varying astronomical quantity.

See Epsilon Pyxidis and Epoch (astronomy)

Frequency

Frequency (symbol f), most often measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time.

See Epsilon Pyxidis and Frequency

Glossary of astronomy

This glossary of astronomy is a list of definitions of terms and concepts relevant to astronomy and cosmology, their sub-disciplines, and related fields.

See Epsilon Pyxidis and Glossary of astronomy

International Celestial Reference System and its realizations

The International Celestial Reference System (ICRS) is the current standard celestial reference system adopted by the International Astronomical Union (IAU).

Light-year

A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi.

See Epsilon Pyxidis and Light-year

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.

See Epsilon Pyxidis and Minute and second of arc

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.

See Epsilon Pyxidis and Monthly Notices of the Royal Astronomical Society

Photosphere

The photosphere is a star's outer shell from which light is radiated.

See Epsilon Pyxidis and Photosphere

Pyxis

Pyxis is a small and faint constellation in the southern sky.

See Epsilon Pyxidis and Pyxis

Sirius

Sirius is the brightest star in the night sky. Epsilon Pyxidis and Sirius are bright Star Catalogue objects, Henry Draper Catalogue objects and Hipparcos objects.

See Epsilon Pyxidis and Sirius

Solar luminosity

The solar luminosity is a unit of radiant flux (power emitted in the form of photons) conventionally used by astronomers to measure the luminosity of stars, galaxies and other celestial objects in terms of the output of the Sun.

See Epsilon Pyxidis and Solar luminosity

Solar mass

The solar mass is a standard unit of mass in astronomy, equal to approximately.

See Epsilon Pyxidis and Solar mass

Stellar classification

In astronomy, stellar classification is the classification of stars based on their spectral characteristics.

See Epsilon Pyxidis and Stellar classification

Stellar parallax

Stellar parallax is the apparent shift of position (parallax) of any nearby star (or other object) against the background of distant stars.

See Epsilon Pyxidis and Stellar parallax

Subgiant

A subgiant is a star that is brighter than a normal main-sequence star of the same spectral class, but not as bright as giant stars.

See Epsilon Pyxidis and Subgiant
