Abstract The Transneptunian Automated Occultation Survey (TAOS II) is a blind occultation survey with the aim of measuring size distribution Trans-Neptunian Objects diameters in range 0.3 ≲ D 30 km. TAOS II will observe as many 10,000 stars at cadence 20 Hz all three telescopes simultaneously. This produce up to ∼20 billion photometric measurements per night, and ∼6 trillion year, corresponding over 70 million individual light curves. A very fast analysis pipeline for event detection...
We present a new occultation event simulator for the Trans-Neptunian Automated Occultation Survey (TAOS II). have developed method to compute shadows by small objects with non-circular apparent shapes (as may result from an intrinsic morphology or projection of contact binary). The calculates diffraction features in shadows, as well resulting light curves would be measured TAOS II survey system. include effects such spectral type and finite angular size occulted star. find that events,...
Abstract In this paper we present multiband speckle interferometric measurements of double stars performed at the 2.1 m telescope Observatorio Astronómico Nacional, San Pedro Mártir, México. We focused our efforts on objects from Washington Double Star Catalog that were observed during five runs allocated in 2018 and 2019. report here 2101 astrometric 2027 photometric 631 pairs, with angular separations ranging 0.″05 to 6.″09, including 1622 smaller than 1″, a magnitude difference up 5.99...
In this paper we study the effects of systematic noise and atmospheric turbulence on image quality signal-to-noise ratio for high cadence (∼20 fps) observations, in context fortuitous stellar occultation surveys. We performed an analysis spatial distribution weighted centroid a reference star, X Y direction (in detector), also analyze FWHM behavior to effect profile. This information allowed us find both shift deformation each image, which are most significant such images. Our observations...
Abstract We present a new pipeline based on the Support Vector Machine algorithm to confirm detection and perform classification of small solar system objects by serendipitous stellar occultations. This is designed analyze light curves identify occultation events occulting bodies according their size, typically from fraction few kilometers, distance Sun, tens astronomical units. The input for this were obtained event simulator Trans-Neptunian Automated Occultation Survey (TAOS II). explore...
