Abstract

The F0V star 9 Aur A exhibits an irregular or multiperiodic variability of amplitude ≈ 0.1 mag at optical wavelengths. The variations are too slow for it to be a δ Scutitype star. There is no evidence for a close, interacting companion or ring of dust, from infrared, ultraviolet or speckle data. The photometric variability of 9 Aur A is similar to that of two other early-F dwarf stars: HD 96008 and γ Doradus. 9 Aur B appears to be an M dwarf, 9 Aur C is an early- to mid-K dwarf star, and 9 Aur E, if it is a member of the system, is probably a normal white dwarf. 9 Aur D is probably an unrelated and distant K giant.
