Dwarf nova

A dwarf nova (pl. novae), or U Geminorum variable, is one of several types of cataclysmic variable star, consisting of a close binary star system in which one of the components is a white dwarf that accretes matter from its companion. ^[1]

Dwarf novae

Accretion disk

An accretion disk is a structure (often a circumstellar disk) formed by diffuse material in orbital motion around a massive central body. Dwarf nova and accretion disk are binary stars.

See Dwarf nova and Accretion disk

American Association of Variable Star Observers

The American Association of Variable Star Observers (AAVSO) is an international nonprofit organization.

Apparent magnitude

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

See Dwarf nova 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. Dwarf nova and binary star are binary stars.

Brian Warner (astronomer)

Brian Warner (25 May 1939 – 5 May 2023) was a British South African optical astronomer who was Emeritus Distinguished Professor of natural philosophy at the University of Cape Town.

Cataclysmic variable star

In astronomy, cataclysmic variable stars (CVs) are stars which irregularly increase in brightness by a large factor, then drop back down to a quiescent state. Dwarf nova and cataclysmic variable star are binary stars.

Cosmic distance ladder

The cosmic distance ladder (also known as the extragalactic distance scale) is the succession of methods by which astronomers determine the distances to celestial objects.

See Dwarf nova and Cosmic distance ladder

Eclipse

An eclipse is an astronomical event which occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. Dwarf nova and eclipse are astronomical events.

See Dwarf nova and Eclipse

ER Ursae Majoris

ER Ursae Majoris is a variable star in the northern circumpolar constellation of Ursa Major, abbreviated ER UMa.

See Dwarf nova and ER Ursae Majoris

European Southern Observatory

The European Organisation for Astronomical Research in the Southern Hemisphere, commonly referred to as the European Southern Observatory (ESO), is an intergovernmental research organisation made up of 16 member states for ground-based astronomy.

Hubble Space Telescope

The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation.

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.

See Dwarf nova and Light curve

Luminosity

Luminosity is an absolute measure of radiated electromagnetic energy (light) per unit time, and is synonymous with the radiant power emitted by a light-emitting object.

See Dwarf nova and Luminosity

Nova

A nova (novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star (hence the name "nova", Latin for "new") that slowly fades over weeks or months. Dwarf nova and nova are astronomical events.

See Dwarf nova and Nova

SS Cygni

SS Cygni is a variable star in the northern constellation Cygnus (the Swan). Dwarf nova and sS Cygni are dwarf novae.

See Dwarf nova and SS Cygni

SU Ursae Majoris

SU Ursae Majoris, or SU UMa, is a close binary star in the northern circumpolar constellation of Ursa Major. Dwarf nova and sU Ursae Majoris are dwarf novae.

See Dwarf nova and SU Ursae Majoris

Superhump

In astronomy, a superhump is a periodic brightness variation in a cataclysmic variable star system, with a period within a few percent of the orbital period of the system. Dwarf nova and superhump are dwarf novae.

See Dwarf nova and Superhump

Temperature

Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness.

See Dwarf nova and Temperature

U Geminorum

U Geminorum (U Gem), in the constellation Gemini, is an archetypal example of a dwarf nova. Dwarf nova and u Geminorum are dwarf novae.

See Dwarf nova and U Geminorum

V band

The V band ("vee-band") is a standard designation by the Institute of Electrical and Electronics Engineers (IEEE) for a band of frequencies in the microwave portion of the electromagnetic spectrum ranging from 40 to 75 gigahertz (GHz).

See Dwarf nova and V band

Viscosity

The viscosity of a fluid is a measure of its resistance to deformation at a given rate.

See Dwarf nova and Viscosity

White dwarf

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

See Dwarf nova and White dwarf

WZ Sagittae

WZ Sagittae (WZ Sge) is a cataclysmic dwarf nova star system in the constellation Sagitta. Dwarf nova and WZ Sagittae are dwarf novae.

See Dwarf nova and WZ Sagittae

Z Camelopardalis

Z Camelopardalis (Z Cam) is a cataclysmic variable star system in the northern constellation of Camelopardalis. Dwarf nova and z Camelopardalis are dwarf novae.

See Dwarf nova and Z Camelopardalis
