Apparent magnitude

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

See 7 Boötis and Apparent magnitude

Boötes

Boötes is a constellation in the northern sky, located between 0° and +60° declination, and 13 and 16 hours of right ascension on the celestial sphere.

See 7 Boötis and Boötes

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 7 Boötis 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 7 Boötis and Effective temperature

Giant star

A giant star has a substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature.

See 7 Boötis and Giant star

Hertzsprung gap

The Hertzsprung gap is a feature of the Hertzsprung–Russell diagram for a star cluster.

See 7 Boötis and Hertzsprung gap

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 7 Boötis and Light-year

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 7 Boötis and Monthly Notices of the Royal Astronomical Society

Northern celestial hemisphere

The northern celestial hemisphere, also called the Northern Sky, is the northern half of the celestial sphere; that is, it lies north of the celestial equator.

See 7 Boötis and Northern celestial hemisphere

Photosphere

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

See 7 Boötis and Photosphere

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 7 Boötis and Radial velocity

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 7 Boötis and Solar luminosity

Solar mass

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

See 7 Boötis and Solar mass

Solar radius

Solar radius is a unit of distance used to express the size of stars in astronomy relative to the Sun.

See 7 Boötis and Solar radius

Star

A star is a luminous spheroid of plasma held together by self-gravity.

See 7 Boötis and Star

Stellar classification

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

See 7 Boötis and Stellar classification

Stellar evolution

Stellar evolution is the process by which a star changes over the course of its lifetime and how it can lead to the creation of a new star.

See 7 Boötis and Stellar evolution

Stellar magnetic field

A stellar magnetic field is a magnetic field generated by the motion of conductive plasma inside a star.

See 7 Boötis and Stellar magnetic field

Stellar rotation

Stellar rotation is the angular motion of a star about its axis.

See 7 Boötis and Stellar rotation

X-ray

X-rays (or rarely, X-radiation) are a form of high-energy electromagnetic radiation.

See 7 Boötis and X-ray
