Observational analysis detected variable stars and supernovae using images from the Javalambre survey, highlighting its discovery potential.
The Javalambre VARiability Survey (J-VAR) is a photometric survey that is being carried out with the 0.8m Javalambre Auxiliary Survey Telescope, located at the Observatorio Astrofísico de Javalambre (Teruel, Spain), using a subset of seven filters from J-PLUS, covering the wavelength range 0.39-0.88 μm. The scientific objectives of J-VAR are three: characterization of variable stars, detection of supernovae, and detection and characterization of small Solar System objects. The main goal of this work is to present the first catalog of Solar System objects (SSOs) compiled from the first data release (DR1) of the J-VAR survey, consisting of observations for 101 fields (visited at least 11 times each). We used the ssos pipeline to analyze each epoch (which usually consists of 21 images, except for the high frequency cases) for all the fields in the J-VAR DR1, retrieving the SSOs detected in the survey images. We analyzed more than 30 000 images, recovering 131 966 detections, corresponding to a total of 6579 individual Solar System Small Bodies, ∼95% of which are located in the Main Belt. We present here two catalogs: individual detections and combined magnitudes. In addition, we show some preliminary results: analysis of color-color plots and comparison with the known spectral properties of asteroids, photospectra for some objects observed in all seven filters, and we present a method for constructing partial lightcurves for objects detected in the high frequency epochs. Finally, we discuss the survey’s potential to discover unkown Solar System bodies.
