13260 Sabadell,prov. designation:1998 QZ15, is a stonyEunomia asteroid from the central region of theasteroid belt. It was discovered by Catalan amateur astronomersFerran Casarramona andAntoni Vidal at theMontjoia Observatory (953), Barcelona, on 23 August 1998.[1] The likely elongated asteroid measures approximately 5.3 kilometers (3.3 miles) in diameter and has arotation period of 5.3 hours.[9] It was named after theastronomical society "Agrupació Astronòmica de Sabadell".[2]
Sabadell is a core member of theEunomia family (502),[3][4] a large group ofS-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun in thecentral main-belt at a distance of 2.1–2.9 AU once every 4 years and 1 month (1,486 days;semi-major axis of 2.55 AU). Its orbit has aneccentricity of 0.16 and aninclination of 13° with respect to theecliptic.[5] A firstprecovery was taken atPalomar Observatory in January 1952, extending the asteroid'sobservation arc by 46 years prior to its official discovery atMontjoia Observatory.[1]
Thisminor planet was named for the well known Catalan–Spanish amateurastronomical societyAgrupació Astronómica de Sabadell, which celebrated its 40th anniversary in 2000. Both discoverers are members of this society.[2] The approvednaming citation was published by theMinor Planet Center on 26 July 2000 (M.P.C. 41032).[10] The society uses the Observatorio de Sabadell (619), one of the country's most prolific amateur observatories, located in a park in the center of Sabadell, near Barcelona, Spain.[11]
In 2006, a rotationallightcurve was obtained fromphotometric observations by Italian astronomersSilvano Casulli andAntonio Vagnozzi. It gave a well-definedrotation period of6.4366±0.0007 hours with a high brightness amplitude of0.56±0.01 inmagnitude (U=3), indicative of an elongated, non-spherical shape.[8][9]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, the asteroid measures 5.3 kilometers in diameter and has a high surfacealbedo of 0.31,[6] while theCollaborative Asteroid Lightcurve Link assumes an albedo of 0.21 and calculates a diameter of 6.1 kilometers, as the lower the body's albedo (reflectivity) the higher its diameter, at a constant absolute magnitude (brightness).[9]
