Main-belt asteroid
1084 Tamariwa , provisional designation1926 CC , is a carbonaceous backgroundasteroid approximately 27 kilometres in diameter from the central regions of theasteroid belt . It was discovered on 12 February 1926, by Soviet astronomerSergey Belyavsky at theSimeiz Observatory on the Crimean peninsula.[ 19] Tamara Ivanova , who died at an early age.[ 2]
Orbit and classification [ edit ] Tamariwa is a non-family asteroid from the main belt'sbackground population .[ 4] central asteroid belt at a distance of 2.3–3.0 AU once every 4 years and 5 months (1,610 days;semi-major axis of 2.69 AU). Its orbit has aneccentricity of 0.13 and aninclination of 4° with respect to theecliptic .[ 1]
The body'sobservation arc begins at Simeiz with its identification as1927 JB in May 1927, more than 14 months after its official discovery observation.[ 19]
Physical characteristics [ edit ] Tamariwa is a common carbonaceousC-type asteroid .[ 3]
Several rotationallightcurves ofTamariwa with arotation period between 6.153 and 7.08 hours have been obtained from photometric observations since 1984.[ 10] [ 11] [ 12] [ 13] [ 14] [ 15] [ 16] [ 17] [ 18] Pierre Antonini gave a period of 6.1961 hours with a brightness amplitude of 0.42magnitude (U=3 [ 3] [ 16]
Diameter and albedo [ edit ] According to the surveys carried out by the Infrared Astronomical SatelliteIRAS , the JapaneseAkari satellite and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer ,Tamariwa measures between 24.71 and 30.681 kilometers in diameter and its surface has analbedo between 0.0916 and 0.15.[ 5] [ 6] [ 7] [ 8] [ 9]
TheCollaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.1165 and a diameter of 27.19 kilometers based on anabsolute magnitude of 10.78.[ 3]
Thisminor planet was named "Tamariwa" after Soviet parachutist Tamara Ivanova (1912–1936). The minor planets1062 Ljuba and1086 Nata were also named after Soviet female paratroopers Lyuba Berlin (1915–1936) and Nata Babushkina (1915–1936), respectively.[ 2]
