Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See 8 Aquilae and Apparent magnitude
Aquila (constellation)
Aquila is a constellation on the celestial equator.
See 8 Aquilae and Aquila (constellation)
Celestial equator
The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth.
See 8 Aquilae and Celestial equator
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 8 Aquilae and Constellation
Delta Scuti variable
A Delta Scuti variable (sometimes termed dwarf cepheid when the V-band amplitude is larger than 0.3 mag.) is a subclass of young pulsating star. 8 Aquilae and Delta Scuti variable are Delta Scuti variables.
See 8 Aquilae and Delta Scuti variable
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 8 Aquilae 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 8 Aquilae and Flamsteed designation
Giant star
A giant star has a substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature.
Light curve
In astronomy, a light curve is a graph of the light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y-axis and with time on the x-axis.
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 8 Aquilae 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 8 Aquilae 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 8 Aquilae and Solar luminosity
Solar mass
The solar mass is a standard unit of mass in astronomy, equal to approximately.
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 8 Aquilae 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 8 Aquilae and Stellar evolution
Stellar rotation
Stellar rotation is the angular motion of a star about its axis.
See 8 Aquilae and Stellar rotation
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.
