    Rapidly Varying Ionization Features in a Quasi-periodic Eruption: A Homologous Expansion Model for the Spectroscopic Evolution by Joheen Chakraborty, Peter Kosec, Erin Kara, Giovanni Miniutti, Riccardo Arcodia, Ehud Behar, Margherita Giustini, Lorena Hernández-García, Megan Masterson, Erwan Quintin, Claudio Ricci, Paula Sánchez-Sáez

    Published 2025-01-01
    “…We interpret our results with orbiter–disk collisions in an EMRI system, in which each impact drives a shock that locally heats the disk and expels X-ray-emitting debris undergoing radiation-pressure-driven homologous expansion. We explore an analytical toy model that links the rapid change in absorption lines to the evolution of the ionization parameter and the photosphere radius, and we suggest that ∼10 ^−3 M _⊙ ejected per eruption with expansion velocities up to ${v}_{{\rm{\max }}}\sim 0.15c$ can reproduce the absorption features. …”
