Amplitude
The amplitude of a periodic variable is a measure of its change over a single period (such as time or spatial period).

Apparent magnitude
The apparent magnitude of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth.
New!!: Mu Coronae Borealis and Apparent magnitude · See more »
Asymptotic giant branch
The asymptotic giant branch (AGB) is a region of the Hertzsprung–Russell diagram populated by evolved cool luminous stars.

Constellation
A constellation is a group of stars that are considered to form imaginary outlines or meaningful patterns on the celestial sphere, typically representing animals, mythological people or gods, mythological creatures, or manufactured devices.

Corona Borealis
Corona Borealis is a small constellation in the Northern Celestial Hemisphere.
New!!: Mu Coronae Borealis and Corona Borealis · See more »
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.

Epoch (astronomy)
In astronomy, an epoch is a moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or elliptical orbital elements of a celestial body, because these are subject to perturbations and vary with time.

Frequency
Frequency is the number of occurrences of a repeating event per unit of time.
New!!: Mu Coronae Borealis and Frequency · See more »
International Celestial Reference System
The International Celestial Reference System (ICRS) is the current standard celestial reference system adopted by the International Astronomical Union (IAU).

Latinisation of names
Latinisation or Latinization is the practice of rendering a non-Latin name (or word) in a Latin style.
New!!: Mu Coronae Borealis and Latinisation of names · See more »
Light-year
The light-year is a unit of length used to express astronomical distances and measures about 9.5 trillion kilometres or 5.9 trillion miles.
New!!: Mu Coronae Borealis and Light-year · See more »
Minute and second of arc
A minute of arc, arcminute (arcmin), arc minute, or minute arc is a unit of angular measurement equal to of one degree.
New!!: Mu Coronae Borealis and Minute and second of arc · See more »
Monthly Notices of the Royal Astronomical Society
Monthly Notices of the Royal Astronomical Society (MNRAS) is a peer-reviewed scientific journal covering research in astronomy and astrophysics.

Photosphere
The photosphere is a star's outer shell from which light is radiated.
New!!: Mu Coronae Borealis and Photosphere · See more »
Red giant
A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses) in a late phase of stellar evolution.
New!!: Mu Coronae Borealis and Red giant · See more »
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.

Star
A star is type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.
New!!: Mu Coronae Borealis and Star · See more »
Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
New!!: Mu Coronae Borealis and Stellar classification · See more »
Stellar evolution
Stellar evolution is the process by which a star changes over the course of time.
New!!: Mu Coronae Borealis and Stellar evolution · See more »
Stellar parallax
Stellar parallax is the apparent shift of position of any nearby star (or other object) against the background of distant objects.
New!!: Mu Coronae Borealis and Stellar parallax · See more »
Sun
The Sun is the star at the center of the Solar System.
New!!: Mu Coronae Borealis and Sun · See more »
Variable star
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates.
