    1301 Yvonne, provisional designation 1934 EA, is a carbonaceous asteroid from the background population of the intermediate asteroid belt, approximately 21 kilometers in diameter. It was discovered on 7 March 1934, by French astronomer Louis Boyer at the Algiers Observatory in North Africa.[17] The asteroid was named for the discoverer's sister, Yvonne Boyer

    Orbit and classification

    Yvonne is a non-family background asteroid.[4] It orbits the Sun in the central main-belt at a distance of 2.0–3.5 AU once every 4 years and 7 months (1,682 days; semi-major axis of 2.77 AU). Its orbit has an eccentricity of 0.27 and an inclination of 34° with respect to the ecliptic.[1] The body's observation arc begins with its official discovery observation at Algiers in March 1934.[17]

    Physical characteristics

    In the SMASS classification, Yvonne is a carbonaceous C-type asteroid.[1] PanSTARRS photometric survey also characterized the asteroid as a C-type.[16]

    Rotation period and pole

    Between 2003 and 2017, four rotational lightcurves of Yvonne have been obtained from photometric observations.[12][14][15] Analysis gave a consolidated rotation period of 7.320 hours with a brightness amplitude between 0.52 and 0.90 magnitude (U=3/3/3/3).[3]

    In 2011, a modeled lightcurve using data from the Uppsala Asteroid Photometric Catalogue (UAPC) and other sources gave a concurring period 7.31968 hours, as well as a spin axis of (39.0°, 41.0°) in ecliptic coordinates (λ, β).[13]

    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, Yvonne measures between 18.693 and 22.77 kilometers in diameter and its surface has an albedo between 0.10 and 0.201.[5][6][7][8][9][10][11]

    The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1054 (which is untypically high for a carbonaceous body) and a diameter of 22.50 kilometers based on an absolute magnitude of 11.3.[3]

    Naming

    This minor planet was named after Yvonne Boyer, sister of discoverer. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 101).[2]
