Absolute magnitude
In astronomy, absolute magnitude is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale.
See W Aquilae and Absolute magnitude
American Association of Variable Star Observers
The American Association of Variable Star Observers (AAVSO) is an international nonprofit organization.
See W Aquilae and American Association of Variable Star Observers
Aquila (constellation)
Aquila is a constellation on the celestial equator.
See W Aquilae and Aquila (constellation)
Astrophysical maser
An astrophysical maser is a naturally occurring source of stimulated spectral line emission, typically in the microwave portion of the electromagnetic spectrum.
See W Aquilae and Astrophysical maser
Asymptotic giant branch
The asymptotic giant branch (AGB) is a region of the Hertzsprung–Russell diagram populated by evolved cool luminous stars.
See W Aquilae and Asymptotic giant branch
Atacama Large Millimeter Array
The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of 66 radio telescopes in the Atacama Desert of northern Chile, which observe electromagnetic radiation at millimeter and submillimeter wavelengths.
See W Aquilae and Atacama Large Millimeter Array
Celestial equator
The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth.
See W 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 W Aquilae and Constellation
IRAS
The Infrared Astronomical Satellite (Dutch: Infrarood Astronomische Satelliet) (IRAS) was the first space telescope to perform a survey of the entire night sky at infrared wavelengths.
Kelvin
The kelvin, symbol K, is the base unit of measurement for temperature in the International System of Units (SI).
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 W Aquilae and Main sequence
Mira
Mira, designation Omicron Ceti (ο Ceti, abbreviated Omicron Cet, ο Cet), is a red-giant star estimated to be 200–300 light-years from the Sun in the constellation Cetus. W Aquilae and Mira are Binary stars, emission-line stars and Mira variables.
Mira variable
Mira variables (named for the prototype star Mira) are a class of pulsating stars characterized by very red colours, pulsation periods longer than 100 days, and amplitudes greater than one magnitude in infrared and 2.5 magnitude at visual wavelengths. W Aquilae and Mira variable are Mira variables.
See W Aquilae and Mira variable
Periodic table
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups").
See W Aquilae and Periodic table
Planets beyond Neptune
Following the discovery of the planet Neptune in 1846, there was considerable speculation that another planet might exist beyond its orbit.
See W Aquilae and Planets beyond Neptune
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.
S-type star
An S-type star (or just S star) is a cool giant with approximately equal quantities of carbon and oxygen in its atmosphere. W Aquilae and s-type star are s-type stars.
Silicon monoxide
Silicon monoxide is the chemical compound with the formula SiO where silicon is present in the oxidation state +2.
See W Aquilae and Silicon monoxide
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 W Aquilae and Solar radius
Solar System
The Solar SystemCapitalization of the name varies.
See W Aquilae and Solar System
Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
See W Aquilae and Stellar classification
Technetium
Technetium is a chemical element; it has symbol Tc and atomic number 43.
Tycho-2 Catalogue
The Tycho-2 Catalogue is an astronomical catalogue of more than 2.5 million of the brightest stars.
See W Aquilae and Tycho-2 Catalogue
Variable star
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) changes with time.
See W Aquilae and Variable star
Variable-star designation
In astronomy, a variable-star designation is a unique identifier given to variable stars. W Aquilae and variable-star designation are objects with variable star designations.
See W Aquilae and Variable-star designation
2MASS
The Two Micron All-Sky Survey, or 2MASS, was an astronomical survey of the whole sky in infrared light. W Aquilae and 2MASS are 2MASS objects.
