1017 Jacqueline

1017 Jacqueline (prov. designation: A924 CH or 1924 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]

    gollark: Fine, I kick the monster again I guess, since that "works".
    gollark: I give it directions to the aforementioned ethical glass.
    gollark: I tell it to find the ethical glass and tell it.
    gollark: I tell the cave bee that the monster is being mean, so it can deal with this.
    gollark: The cave exit with the cave bee.
