LSST Project & Community Workshop SS blending session

Small Solar System Object Platform

SLIDE 2

Motivation

Study of small Solar System bodies
Focus on the stellar occultation technique
Focus on big data

Be ready for the LSST

SLIDE 3

Basic tasks

Metadata info download
Identification of known Solar System bodies
Download frames of interest
Astrometry
Orbit refinement
Prediction of stellar occultations
Observational campaign (worldwide collaboration)
Organize/store observations
Sizes/shapes/atmospheres/rings/etc

Comments

Back-end codes exist!
Procedures tested on DES images (more than 4.2M CCDs or ~67K pointings

from NOV2012 to FEB2016).

Small body search: from 6 months to less than 1 day for the above data.
All known TNOs/Centaurs in these images went through the pipeline

(Astrometry and occultation predictions to transneptunian and centaur

bjects observed within the dark energy survey – under internal review by

the collaboration).

Implementation of the codes in the context of the SSSO platform is ongoing

(~60% implemented). http://www.linea.gov.br
