It is based on reflectance spectrum characteristics for 371 asteroids measured over the wavelength 0.452.45 micrometers. Credit: Francesca DeMeo, Massachusetts Institute of Technology. The scope of this work is to introduce tools to link future observations into existing Bus-DeMeo taxonomy. The Bus-DeMeo classification is an asteroid taxonomic system designed by Francesca DeMeo, Schelte Bus and Stephen Slivan in 2009. Figure 4.20 Reflectance spectra of the BusDeMeo taxonomic classes (DeMeo et al., 2009). We report here a success ratio in classification up to 90.1% with a reduced set of Bus-DeMeo types for simulated observations using the LSST photometric filters. An extension of the Bus asteroid taxonomy into the near-infrared. This article shows how deep learning techniques with neural networks can be used to classify the upcoming observations, particularly from LSST, into the Bus-DeMeo taxonomic system. The scope of this work is to introduce tools to link future observations into existing Bus-DeMeo taxonomy.ĪB - The Legacy Survey of Space and Time (LSST) is one of the ongoing or future surveys, together with the Gaia and Euclid missions, which will produce a wealth of spectrophotometric observations of asteroids. We report here a success ratio in classification up to 90.1% with a reduced set of Bus-DeMeo types for simulated observations using the LSST photometric filters. N2 - The Legacy Survey of Space and Time (LSST) is one of the ongoing or future surveys, together with the Gaia and Euclid missions, which will produce a wealth of spectrophotometric observations of asteroids. However, we realize that our broadband photometry with the KMTNet telescope cannot distinguish subtle spectral differences among asteroids. T1 - Taxonomy of Asteroids From the Legacy Survey of Space and Time Using Neural Networks The taxonomy used here is mainly based on the BusDeMeo system, which classifies asteroids into 24 classes with high-resolution spectroscopic data (DeMeo et al.
