Characteristics and large bulk density of the C-type main-belt triple asteroid (93) Minerva
Original language description
From a set of adaptive optics (AO) observations collected with the W.M. Keck telescope between August and September 2009, we derived the orbital parameters of the most recently discovered satellites of the large C-type asteroid (93) Minerva. The satellites of Minerva, which are approximately 3 and 4 km in diameter, orbit very close to the primary (similar to 5 and similar to 8 x R-p and similar to 1% and similar to 2% x R-Hill) in a circular manner, sharing common characteristics with most of the tripleasteroid systems in the main-belt. Combining these AO observations with lightcurve data collected since 1980 and two stellar occultations in 2010 and 2011, we removed the ambiguity of the pole solution of Minerva's primary and showed that it has an almost regular shape with an equivalent diameter D-eq = 154 +/- 6 km in agreement with IRAS observations. The surprisingly high bulk density of 1.75 +//- 0.30 g/cm(3) for this C-type asteroid, suggests that this taxonomic class is composed of
