From 3D simulations to tactile astrophysics: accessible models of accretion/ejection processes in young stellar objects

Young Stellar Objects (YSOs) exhibit complex, multi-timescale photometric and spectroscopic variability driven by dynamic accretion and ejection processes occurring within star-disk environments. The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) has started to deliver an unprecedented volume of time-series data on young stellar populations, requiring innovative approaches to interpret and communicate multi-dimensional astrophysical phenomena. However, astronomy’s historical reliance on two-dimensional representations inherently flattens complex three-dimensional geometries for all observers, while creating systemic barriers for researchers and students who are blind or visually impaired (BVI). In this work, we present a framework that bridges high-resolution magnetohydrodynamic (MHD) simulations with accessible tactile data representations. We present two models related with YSO variability: stationary shock in magnetized protostellar jets and flare-triggered magnetospheric accretion funnels. Isosurfaces corresponding to critical physical boundaries are extracted, topologically optimized and manifolded, and fabricated via a resin 3D printer. The resulting physical models allow users to trace looping accretion trajectories and localize shock boundaries through touch, leveraging human tactile pattern recognition to intuitively disentangle 3D structures. The pipeline presented here establishes a reproducible methodology for tactile data exploration, advancing astrophysical analysis, equity, diversity, and inclusion in time-domain science.
