7517 Alisondoane, provisional designation 1989 AD, is a carbonaceous asteroid from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 3 January 1989, by Japanese amateur astronomer Takuo Kojima at the YGCO Chiyoda Station in the northern Kantō region of Japan.[11]

Orbit and classification[]

Alisondoane orbits the Sun in the inner main-belt at a distance of 1.8–3.1 AU once every 3 years and 10 months (1,397 days). Its orbit has an eccentricity of 0.26 and an inclination of 6° with respect to the ecliptic.[1]

Physical characteristics[]

Alisondoane has been characterized as a carbonaceous C-type asteroid by PanSTARRS photometric survey.[10]

Lightcurves[]

A photometric lightcurve analysis by Czech astronomer Petr Pravec in 2007 rendered a rotation period of 9.701±0.001 hours with a high brightness amplitude of 1.13 in magnitude (U=3).[a]

Diameter and albedo[]

According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Alisondoane measures between 8.52 and 9.99 kilometers in diameter and its surface has an albedo between 0.04 and 0.122.[4][5][6][7][8][9] The Collaborative Asteroid Lightcurve Link (CALL) calculates a smaller diameter of 5.16 kilometers based on an assumed albedo of 0.18 for a X-type asteroid.[3][b]

Naming[]

This minor planet was named in honor of Alison Doane (born 1958) a curator of astronomical photographs at the Harvard College Observatory. She was also principal oboe with the Boston Philharmonic Orchestra from 1982 to 2001.[11] The official naming citation was published by the Minor Planet Center on 25 December 2015 (M.P.C. 97567).[12]

Notes[]

  1. ^ a b Pravec (2007): rotation period 9.701±0.001 hours with a brightness amplitude of 1.13 mag. CALL assigns a "Quality Code" of 3, which denotes a secure result within the precision given and no ambiguity. Summary figures for (7517) Alisondoane at Collaborative Asteroid Lightcurve Link (CALL)
  2. ^ a b c Summary Notes by the LCDB: "The Masi et al. paper gave this as a C-type on the basis of a neutral spectrum. However, given its location in the inner main belt, we adopted class X and a Pv = 0.18"
