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

K-type main-sequence star
A K-type main-sequence star (K V), also referred to as an orange dwarf or K dwarf, is a main-sequence (hydrogen-burning) star of spectral type K and luminosity class V. These stars are intermediate in size between red M-type main-sequence stars ("red dwarfs") and yellow G-type main-sequence stars.
