6090 Aulis, provisional designation: 1989 DJ, is a Jupiter trojan from the Greek camp, approximately 70 kilometers (43 miles) in diameter.
[11] On 14 May 2021, the object was named by the Working Group for Small Bodies Nomenclature (WGSBN) for the ancient Greek port Aulis, mentioned in the Iliad.
In June 1994, together with astronomer Anders Erikson, he constructed a lightcurve from observations made with the 0.9-meter Dutch telescope at La Silla, showing a rotation period of 18.60±0.05 hours and a brightness variation of 0.09±0.01 magnitude (U=2+).
In September 2009, he used the 1.2-meter reflector at Calar Alto Observatory, Spain, and measured a refined period of 18.476±0.007 hours with an amplitude of 0.16±0.01 in magnitude (U=2+), confirming his previous result.
[6][7][8] The Collaborative Asteroid Lightcurve Link adopts an albedo of 0.0553 from IRAS, and derives a similar diameter of 74.53 kilometers based on an absolute magnitude of 9.4.
