DI Chamaeleontis, also known as Hen 3-593 or HIP 54365, is a quadruple star system in the constellation Chamaeleon.

DI Cha is a variable star of the T Tauri type, young stellar objects just approaching the main sequence.

[4] Although it is visually faint, it was noticed because of the prominent emission lines in its spectrum.

[9] The B component was discovered to be a pair of stars separated by only 0.066", about 10 AU,[10] both with spectral type M5.5.

[11] Finally, the variable primary star was found to have a faint companion 0.2" (therefore ~30 AU) away, of spectral type M6.
