The astronomical unit (symbol au, AU or ua) is a unit of length, roughly the distance from the Earth to the Sun.
Brown dwarfs are substellar objects not massive enough to sustain hydrogen-1 fusion reactions in their cores, unlike main-sequence stars.

Chamaeleon is a small constellation in the southern sky.

A U Geminorum-type variable star, or dwarf nova (pl. novae) is a type 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.

HW Virginis, abbreviated HW Vir, is an eclipsing binary system (of the Algol type) approximately 590 light-years away (based on the stellar properties and magnitudes: the Hipparcos trigonometric parallax measurement has too high an error value to be useful) in the constellation of Virgo.

A light-year (abbreviation: ly), sometimes written light year, is a unit of length used informally to express astronomical distances.

NN Serpentis (abbreviated NN Ser) is an eclipsing binary system approximately 1670 light-years away, likely forming a cataclysmic variable star.

OY Carinae (abbreviated OY Car) is an eclipsing binary system approximately 277 light-years away from the Sun, classed as cataclysmic variable.

A red dwarf is a small and relatively cool star on the main sequence, either late K or M spectral type.
New!!: Z Chamaeleontis and Red dwarf ·
A substellar object, sometimes called a substar, is an astronomical object whose mass is smaller than the smallest mass at which hydrogen fusion can be sustained (approximately 0.08 solar masses).
The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth.

The Astrophysical Journal, often abbreviated ApJ (pronounced "ap jay") in references and speech, is a peer-reviewed scientific journal of astrophysics, established in 1895 by American astronomers George Ellery Hale and James Edward Keeler.
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates.

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