To What Extent Are Star Cluster Ages Encoded in Their Environments? Exploring the Spatial Distribution of Age-Related Information with PHANGS-HST Imaging and Convolutional Neural Networks

Javier Viaña, Janice C. Lee, Andrew Vanderburg +12

The environments around star clusters evolve as stellar feedback reshapes the interstellar medium and dynamical processes reorganize the structure of the surrounding stellar field.…

Identifying Exoplanets with Deep Learning VI. Enhancing neural network mitigation of stellar activity RV signals with additional metrics

Naomi McWilliam, Zoë L. de Beurs, Andrew Vanderburg +12

The measurement of exoplanet masses using the radial velocity (RV) technique is currently limited by stellar activity, which introduces quasiperiodic variability signals that must…

LensNet: Enhancing Real-time Microlensing Event Discovery with Recurrent Neural Networks in the Korea Microlensing Telescope Network

Javier Viaña, Kyu-Ha Hwang, Zoë de Beurs +20

Traditional microlensing event vetting methods require highly trained human experts, and the process is both complex and time-consuming. This reliance on manual inspection often le…

Absence of a Correlation between White Dwarf Planetary Accretion and Primordial Stellar Metallicity

Sydney Jenkins, Andrew Vanderburg, Allyson Bieryla +8

Over a quarter of white dwarfs have photospheric metal pollution, which is evidence for recent accretion of exoplanetary material. While a wide range of mechanisms have been propos…

Front-propagation Algorithm: Explainable AI Technique for Extracting Linear Function Approximations from Neural Networks

Javier Viaña

This paper introduces the front-propagation algorithm, a novel eXplainable AI (XAI) technique designed to elucidate the decision-making logic of deep neural networks. Unlike other…
