    1017 Jacqueline, provisional designation 1924 QL, is a carbonaceous background asteroid from the central regions of the asteroid belt, approximately 35 kilometers (22 miles) in diameter. It was discovered on 4 February 1924, by Russian-French astronomer Benjamin Jekhowsky at the Algiers Observatory, Algeria, in North Africa.[1] It was named after Jacqueline Eisenmann (née Zadoc-Kahn), a long-time pupil of the discoverer.[2] The C-type asteroid has a rotation period of 7.87 hours with a high brightness amplitude of 0.7 magnitude.[4]

    Orbit and classification

    Jacqueline is a non-family asteroid from the main belt's background population.[5] It orbits the Sun in the intermediate asteroid belt at a distance of 2.4–2.8 AU once every 4 years and 2 months (1,535 days; semi-major axis of 2.6 AU). Its orbit has an eccentricity of 0.08 and an inclination of 8° with respect to the ecliptic.[3]

    The asteroid's earliest preserved observation dates back to 7 March 1924 at Heidelberg Observatory, where the body's observation arc begins in February 1928, nearly four years after its official discovery observation at Algiers–Bouzaréah.[1]

    Physical characteristics

    In the SMASS classification, Jacqueline is a carbonaceous C-type asteroid.[3][4]

    Rotation period

    In May 2000, a rotational lightcurve of Jacqueline was obtained from photometric observations by American photometrist Robert Stephens at the Santana Observatory (646) in California. Analysis of the classically shaped bimodal lightcurve gave a well-defined rotation period of 7.87 hours and a brightness variation of 0.7 magnitude, indicative of a non-spheroidal shape (U=3).[14] Other measurements by Eric Barbotin and by astronomers at the Palomar Transient Factory gave a similar period of 7.873 and 7.875 hours with an amplitude of 0.72 and 0.43 magnitude, respectively (U=3-/2).[16][17]

    In 2016, a lightcurve was published using modeled photometric data from the Lowell Photometric Database. It gave a concurring sidereal period of 7.87149 hours, as well as two spin axes of (7.0°, 55.0°) and (170.0°, 65.0°) in ecliptic coordinates (λ, β).[15]

    Diameter and albedo

    According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Jacqueline measures between 29.523 and 45.056 kilometers in diameter and its surface has a low albedo between 0.0380 and 0.07.[6][7][8][9][10][11][12][13]

    The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0497 and a diameter of 37.61 kilometers based on an absolute magnitude of 11.0.[4]

    Naming

    This minor planet was named after Jacqueline Eisenmann (née Zadoc-Kahn; 1904–1998),[19] a long-time student of Jekhowsky's. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 97).[2]
