    1017 Jacqueline (prov. designation: A924 CHor1924 QL) is a dark background asteroid from the central regions of the asteroid belt. It was discovered on 4 February 1924, by Russian-French astronomer Benjamin Jekhowsky at the Algiers Observatory, Algeria, in North Africa. [1] The carbonaceous C-type asteroid has a rotation period of 7.87 hours with a high brightness amplitude of 0.6 magnitude and measures approximately 39 kilometers (24 miles) in diameter. [10] It was named after the French physicist and long-time pupil of the discoverer, Jacqueline Zadoc-Kahn Eisenmann (1904–1998). [2]

    Orbit and classification

    Jacqueline is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. [4] [5] It orbits the Sun in the intermediate asteroid belt at a distance of 2.4–2.8  AU once every 4 years and 3 months (1,536 days; semi-major axis of 2.61 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]

    Naming

    This minor planet was named after Jacqueline Zadoc-Kahn Eisenmann (1904–1998), [11] a French physicist and long-time student of Jekhowsky's. The naming was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ( H 97 ). [2]

    Physical characteristics

    In the Bus–Binzel SMASS classification, Jacqueline is a common, carbonaceous C-type asteroid. [3] [10]

    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±0.01 hours and a brightness variation of 0.6±0.02 magnitude, indicative of a non-spheroidal shape ( U=3 ). [9] 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 ). [12] [13]

    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). [14]

    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 (37.65±3.4), (38.87±0.51) and (40.152±0.199) kilometers in diameter and its surface has an albedo of (0.0544±0.011), (0.051±0.002) and (0.052±0.005), respectively. [6] [7] [8] 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. [10]

    Alternative mean-diameter measurements published by the WISE team include (29.523±10.14 km), (30.09±11.84 km), (31.991±0.454 km), (32.631±9.058 km) and (45.056±0.325 km) with corresponding albedos of (0.0670±0.0538), (0.07±0.06), (0.069±0.012), (0.06±0.02) and (0.0380±0.0053). [5] [10]
