Descripción del proyecto
En una misión astrofísica para explorar la formación de estrellas
A fin de explorar la mayor colección de datos pancromáticos de objetos estelares jóvenes, se utilizarán datos masivos y métodos híbridos de aprendizaje automático. El proyecto NEMESIS, financiado con fondos europeos, allana el camino hacia las aplicaciones científicas con un uso intensivo de datos en la astrofísica moderna y mejorará nuestra comprensión de la formación de las estrellas. Pruebas recientes sugieren que los planetas se forman al mismo tiempo que las estrellas que orbitan, y no después, lo que indica una rápida evolución temprana de los sistemas planetarios con una estrella. NEMESIS determinará las transiciones características que describen cada fase de la formación estelar. En concreto, revisará el actual esquema de clasificación y sus escalas de tiempo particulares para que coincida con las restricciones observacionales y teóricas más recientes.
Objetivo
NEMESIS has the ambition to reshape our understanding on the formation of stars by employing artificial intelligence methods to interpret the largest, panchromatic data collection of young stellar objects. Recent evidence suggests that planets form synchronously rather than sequentially to their host stars, indicating a rapid early evolution of star-planet systems. To ascertain these timescales, it is necessary to first determine the characteristic transitions that describe each phase of star formation. The definition of classes for young stellar objects was made possible more than 30 years ago, due to the first space-based infrared sky surveys. Whilst successful in determining global properties, current classification is prone to large uncertainties, and therefore, timescales, which are based on population statistics among different classes in a steady-state evolution, remain dubious.
NEMESIS aims to readjust the current classification scheme and its characteristic timescales so that it is concurrent with the most recent observational and theoretical constraints. To meet these goals NEMESIS will compile the largest, panchromatic dataset comprising of all young stellar objects in nearby star-forming regions, harnessing critical information that resides in data from space missions. It will reprocess and analyze this unique dataset with supervised and unsupervised machine learning algorithms, deep learning neural networks for object detection, clustering and regression analysis of images in order to advance the analysis and interpretation beyond the current state-of-the-art. Ultimately, NEMESIS brings big data techniques and hybrid machine learning methods to systematically analyze and interpret large data volumes in order to answer some of the most persisting questions, paving the path toward data-intensive science applications in modern astrophysics.
