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). 1 Boötis and a-type main-sequence star are a-type main-sequence stars.

See 1 Boötis and A-type main-sequence 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 1 Boötis and Angular distance

Apparent magnitude

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

See 1 Boötis and Apparent magnitude

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 1 Boötis and Binary star

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 1 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 1 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 1 Boötis and Effective temperature

International Astronomical Union

The International Astronomical Union (IAU; Union astronomique internationale, UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation.

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.

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 1 Boötis and Monthly Notices of the Royal Astronomical Society

Photosphere

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

See 1 Boötis and Photosphere

Pre-main-sequence star

A pre-main-sequence star (also known as a PMS star and PMS object) is a star in the stage when it has not yet reached the main sequence.

See 1 Boötis and Pre-main-sequence star

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 1 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 1 Boötis and Solar luminosity

Solar mass

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

See 1 Boötis and Solar mass

Stellar classification

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

See 1 Boötis and Stellar classification

Stellar rotation

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

See 1 Boötis and Stellar rotation

X-ray astronomy

X-ray astronomy is an observational branch of astronomy which deals with the study of X-ray observation and detection from astronomical objects.

See 1 Boötis and X-ray astronomy
