Main-belt asteroid
7517 Alisondoane (prov. designation 1989 AD ) is a darkbackground asteroid from the inner regions of theasteroid belt . It was discovered on 3 January 1989, by Japanese amateur astronomerTakuo Kojima at theYGCO Chiyoda Station in the northern Kantō region of Japan. The carbonaceousC-type asteroid has arotation period of 9.7 hours and measures approximately 9 kilometers (5.6 miles) in diameter. It was named after Alison Doane (1958–2017), curator of astronomical photographs at theHarvard College Observatory .[ 1]
Orbit and classification [ edit ] Alisondoane is a non-family asteroid of the main belt'sbackground population when applying thehierarchical clustering method to itsproper orbital elements .[ 5] [ 6] [ 7] 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 aneccentricity of 0.26 and aninclination of 6° with respect to theecliptic .[ 3]
Thisminor planet was named in honor of Alison Doane (1958–2017), curator of astronomical photographs at theHarvard College Observatory . She was also principal oboe with theBoston Philharmonic Orchestra from 1982 to 2001.[ 1] official naming citation was published by theMinor Planet Center on 25 December 2015 (M.P.C. 97567[ 17]
Physical characteristics [ edit ] Alisondoane has been characterized as a carbonaceousC-type asteroid byPanSTARRS photometric survey,[ 15] Sloan Digital Sky Survey (SDSS).[ 16]
A rotationallightcurve analysis by Czech astronomerPetr Pravec in 2007 rendered arotation period of± 0.001magnitude (U=3 [ a] photometric data from various sources, gave a sidereal period of43 spin axes of (123.0°, −51.0°) and (314.0°, −60.0°) inecliptic coordinates (λ, β).[ 14]
Diameter and albedo [ edit ] According to the surveys carried out by the JapaneseAkari satellite and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Alisondoane measures between 8.52 and 9.99 kilometers in diameter and its surface has analbedo between 0.04 and 0.122.[ 8] [ 9] [ 10] [ 11] [ 12] [ 13] Collaborative Asteroid Lightcurve Link (CALL) calculates a smaller diameter of 5.16 kilometers based on an assumed albedo of 0.18 for anX-type asteroid .[ 4] [ b]
