Alert Classification for the ALeRCE Broker System: The Light Curve Classifier [PDF]

Astronomical Journal, 2021
Abstract We present the first version of the Automatic Learning for the Rapid Classification of Events (ALeRCE) broker light curve classifier. ALeRCE is currently processing the Zwicky Transient Facility (ZTF) alert stream, in preparation for the Vera C. Rubin Observatory.

Machine Learning Techniques for Stellar Light Curve Classification [PDF]

Astronomical Journal, 2018
AbstractWe apply machine learning techniques in an attempt to predict and classify stellar properties from noisy and sparse time-series data. We preprocessed over 94 GB ofKeplerlight curves from the Mikulski Archive for Space Telescopes (MAST) to classify according to 10 distinct physical properties using both representation learning and feature ...

Space Objects Classification via Light-Curve Measurements Using Deep Convolutional Neural Networks

Journal of the Astronautical Sciences, 2020
This work presents a data-driven method for the classification of light curve measurements of Space Objects (SOs) based on a deep learning approach. Here, we design, train, and validate a Convolutional Neural Network (CNN) capable of learning to classify

Attitude motion classification of resident space objects using light curve spectral analysis

Advances in Space Research
The characterization of Earth-orbiting objects in terms of attitude motion, material composition, and shape is crucial for Space Domain Awareness. In this respect, light curves, i.e., graphs showing the brightness variation of space objects over a ...

A New Classification Scheme for T Tauri Light Curves

Astronomy Reports, 2005
Based on many years of observational data from a photometric database on young stars, we propose a new classification scheme for the light curves of classical T Tauri stars. Our analysis of master light-curve shapes for 28 classical T Tauri stars is used to distinguish up to five light-curve types.

The Basic Shape Classification of Space Debris with Light Curves

Chinese Astronomy and Astrophysics, 2021
Abstract We study the machine learning method for classifying the basic shape of space debris in both simulated and observed data experiments, where light curves are used as the input features. In the dataset for training and testing, simulated light curves are derived from four types of debris within different shapes and materials.
