Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See 38 Boötis and Apparent magnitude
Arabic
Arabic (اَلْعَرَبِيَّةُ, or عَرَبِيّ, or) is a Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world.
Bayer designation
A Bayer designation is a stellar designation in which a specific star is identified by a Greek or Latin letter followed by the genitive form of its parent constellation's Latin name.
See 38 Boötis and Bayer designation
Billhook
A billhook or bill hook, also called a pruning knife or spar hook, is a versatile cutting tool used widely in agriculture and forestry for cutting woody material such as shrubs, small trees and branches.
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.
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 38 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 38 Boötis and Effective temperature
Flamsteed designation
A Flamsteed designation is a combination of a number and constellation name that uniquely identifies most naked eye stars in the modern constellations visible from southern England.
See 38 Boötis and Flamsteed designation
IAU Working Group on Star Names
The International Astronomical Union (IAU) established a Working Group on Star Names (WGSN) in May 2016 to catalog and standardize proper names for stars for the international astronomical community.
See 38 Boötis and IAU Working Group on Star Names
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.
See 38 Boötis and International Astronomical Union
Latin
Latin (lingua Latina,, or Latinum) is a classical language belonging to the Italic branch of the Indo-European languages.
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.
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 38 Boötis and Main sequence
Photosphere
The photosphere is a star's outer shell from which light is radiated.
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 38 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 38 Boötis and Solar luminosity
Solar mass
The solar mass is a standard unit of mass in astronomy, equal to approximately.
Solar radius
Solar radius is a unit of distance used to express the size of stars in astronomy relative to the Sun.
See 38 Boötis and Solar radius
Spectral line
A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum.
See 38 Boötis and Spectral line
Star
A star is a luminous spheroid of plasma held together by self-gravity.
Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
See 38 Boötis and Stellar classification
Stellar core
A stellar core is the extremely hot, dense region at the center of a star.
See 38 Boötis and Stellar core
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 38 Boötis and Stellar evolution
Stellar rotation
Stellar rotation is the angular motion of a star about its axis.
See 38 Boötis and Stellar rotation
