Accretion (astrophysics)
In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk.

Accretion disk
An accretion disk is a structure (often a circumstellar disk) formed by diffused material in orbital motion around a massive central body.

Active galactic nucleus
An active galactic nucleus (AGN) is a compact region at the center of a galaxy that has a much higher than normal luminosity over at least some portion—and possibly all—of the electromagnetic spectrum, with characteristics indicating that the excess luminosity is not produced by stars.

AG Draconis
AG Draconis is a binary system consisting of an orange-red giant star and a white dwarf star that revolve around each other every 550 days.

Annie Jump Cannon
Annie Jump Cannon (December 11, 1863 – April 13, 1941) was an American astronomer whose cataloging work was instrumental in the development of contemporary stellar classification.

Apparent magnitude
The apparent magnitude of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth.

Astrophysical jet
An astrophysical jet is an astronomical phenomenon where outflows of ionised matter are emitted as an extended beam along the axis of rotation.

Binary star
A binary star is a star system consisting of two stars orbiting around their common barycenter.

Long-period variable star
The descriptive term long-period variable star refers to various groups of cool luminous pulsating variable stars.

Mira variable
Mira variables ("Mira", Latin, adj. - feminine form of adjective "wonderful"), named for the prototype star Mira, are a class of pulsating variable 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.

Nova
A nova (plural novae or novas) or classical nova (CN, plural CNe) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star, that slowly fades over several weeks or many months.
New!!: Symbiotic binary and Nova · See more »
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.
New!!: Symbiotic binary and Red giant · See more »
Roche lobe
The Roche lobe (or Roche limit) is the region around a star in a binary system within which orbiting material is gravitationally bound to that star.
New!!: Symbiotic binary and Roche lobe · See more »
Spectral energy distribution
A spectral energy distribution (SED) is a plot of energy versus frequency or wavelength of light (not to be confused with a 'spectrum' of flux density vs frequency or wavelength).

Stellar wind
A stellar wind is a flow of gas ejected from the upper atmosphere of a star.
New!!: Symbiotic binary and Stellar wind · See more »
Symbiotic nova
Symbiotic novae are slow irregular eruptive variable stars with very slow nova-like outbursts with an amplitude of between 9 and 11 magnitudes.

The INT Photometric H-Alpha Survey
The INT Photometric H-Alpha Survey (IPHAS) is an astronomical survey of the northern plane of our Galaxy, the Milky Way, as visible from the Isaac Newton Telescope (INT) in the Canary Islands, Spain.

Variable star
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates.

White dwarf
A white dwarf, also called a degenerate dwarf, is a stellar core remnant composed mostly of electron-degenerate matter.
