Asteroid
13260 Sabadell , prov. designation : 1998 QZ15 , is a stony Eunomia asteroid from the central region of the asteroid belt . It was discovered by Catalan amateur astronomers Ferran Casarramona and Antoni Vidal at the Montjoia Observatory (953 ), Barcelona, on 23 August 1998.[ 1] The likely elongated asteroid measures approximately 5.3 kilometers (3.3 miles) in diameter and has a rotation period of 5.3 hours.[ 9] It was named after the astronomical society "Agrupació Astronòmica de Sabadell".[ 2]
Orbit and classification
Sabadell is a core member of the Eunomia family (502 ),[ 3] [ 4] a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun in the central 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 an eccentricity of 0.16 and an inclination of 13° with respect to the ecliptic .[ 5] A first precovery was taken at Palomar Observatory in January 1952, extending the asteroid's observation arc by 46 years prior to its official discovery at Montjoia Observatory .[ 1]
Naming
This minor planet was named for the well known Catalan–Spanish amateur astronomical society Agrupació Astronómica de Sabadell , which celebrated its 40th anniversary in 2000. Both discoverers are members of this society.[ 2] The approved naming citation was published by the Minor 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]
Physical characteristics
Lightcurves
In 2006, a rotational lightcurve was obtained from photometric observations by Italian astronomers Silvano Casulli and Antonio Vagnozzi . It gave a well-defined rotation period of 6.4366± 0.0007 hours with a high brightness amplitude of 0.56± 0.01 in magnitude (U=3 ), indicative of an elongated, non-spherical shape.[ 8] [ 9]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer , the asteroid measures 5.3 kilometers in diameter and has a high surface albedo of 0.31,[ 6] while the Collaborative 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]
