研究目的
To obtain the near-infrared colors for a large sample of solar system objects using the observations made during the VISTA-VHS survey.
研究成果
The colors and the magnitudes of the minor planets observed by the VISTA survey are compiled into three catalogs that are available online. The colors found for asteroids with known spectral properties reveal well-defined patterns corresponding to different mineralogies. The distributions of MOVIS-C data in color?color plots shows clusters identified with different taxonomic types. All the diagrams that use (Y ? J) color separate the spectral classes more effectively than the (J ? H) and (H ? Ks) plots used until now.
研究不足
The study is limited by the coverage of the VISTA-VHS survey and the accuracy of the photometric data. The colors and magnitudes are compiled into three catalogs, but the study does not provide a detailed analysis of each individual object.
1:Experimental Design and Method Selection:
A serendipitous search in VISTA-VHS observations was performed using a pipeline developed to retrieve and process the data corresponding to solar system objects (SSo). The photometric data was analyzed using color?color plots and by comparison with the known spectral properties of asteroids.
2:Sample Selection and Data Sources:
The data was selected from the VISTA-VHS survey, specifically the third data release (VISTA VHS-DR3).
3:3). List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: The VISTA telescope, equipped with a NIR camera with a
4:65? field of view, and with the broad band filters Z, Y, J, H, and Ks. Experimental Procedures and Operational Workflow:
The pipeline performed a serendipitous search in VISTA-VHS observations, retrieved and processed the data corresponding to SSo, and compiled the colors and magnitudes into three catalogs.
5:Data Analysis Methods:
The photometric data was analyzed using color?color plots and by comparison with the known spectral properties of asteroids.
