From Wikipedia, the free encyclopedia
7517 Alisondoane (
prov. designation : 1989 AD ) is a dark
background asteroid from the inner regions of the
asteroid belt . 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. The carbonaceous
C-type asteroid has a
rotation 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 the
Harvard College Observatory .
[1]
Orbit and classification
Alisondoane is a non-
family asteroid of the main belt's
background population when applying the
hierarchical clustering method to its
proper orbital elements .
[5]
[6]
[7] It 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 .
[3]
Naming
This
minor planet was named in honor of Alison Doane (1958–2017), curator of astronomical photographs at the
Harvard College Observatory . She was also principal oboe with the
Boston Philharmonic Orchestra from 1982 to 2001.
[1] The
official naming citation was published by the
Minor Planet Center on 25 December 2015 (
M.P.C. 97567 ).
[17]
Physical characteristics
Alisondoane has been characterized as a carbonaceous
C-type asteroid by
PanSTARRS photometric survey,
[15] as well as by the
Sloan Digital Sky Survey (SDSS).
[16]
Lightcurves
A rotational
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] A modeled lightcurves using
photometric data from various sources, gave a sidereal period of 9.70943 hours and two
spin axes of (123.0°, −51.0°) and (314.0°, −60.0°) in
ecliptic coordinates (λ, β).
[14]
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.
[8]
[9]
[10]
[11]
[12]
[13] The Collaborative Asteroid Lightcurve Link (CALL) calculates a smaller diameter of 5.16 kilometers based on an assumed albedo of 0.18 for an
X-type asteroid .

Notes
^
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

^ 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"
