Phase Anticipation and Magneto-Hydrodynamic Modeling of the SIR-B-01 Exoplanetary System (Sirius B): Predictive Analysis Prior to JWST-MIRI Acquisition.

Abstract

Abstract (English) Title: Phase Anticipation and Magneto-Hydrodynamic Modeling of the SIR-B-01 Exoplanetary System (Sirius B): Predictive Analysis Prior to JWST-MIRI Acquisition. Abstract: This report details the high-fidelity (98.9%) simulation results generated by the NTP-1 processor regarding the potential Super-Earth SIR-B-01 orbiting the white dwarf Sirius B. The study focuses on two critical pillars of planetary resilience within extreme environments. First, we analyze the dynamics of the "Titan" magnetic shield, a high-class magnetosphere (2.8 Gauss) sustained by tidal heating induced by the binary interaction with Sirius A. This protection is vital for the preservation of a 12-bar $CO_2$ atmosphere against the white dwarf’s intense UV flux. Second, the report characterizes the geochemical and spectral signature of the planet's ionic wake. Analysis reveals a "loaded hydrodynamic escape" of heavy metals (Iron, Silicon), confirming permanent friction-induced volcanism that recycles the lithosphere into the exosphere. These models provide a "frozen" theoretical baseline to be validated against upcoming James Webb Space Telescope (MIRI) observational data, representing a milestone in the study of post-red giant planetary habitability.

Résumé : Ce rapport présente les résultats de la simulation haute fidélité (98,9 %) réalisée par le processeur NTP-1 concernant la potentielle Super-Terre SIR-B-01 en orbite autour de la naine blanche Sirius B. L'étude se concentre sur deux piliers critiques de la résilience planétaire en environnement extrême. Premièrement, nous analysons la dynamique du bouclier magnétique "Titan", une magnétosphère de classe supérieure (2,8 Gauss) maintenue par un chauffage de marée induit par l'interaction binaire avec Sirius A. Cette protection est essentielle pour la survie d'une atmosphère de $CO_2$ de 12 bars face au flux UV intense de la naine blanche. Deuxièmement, le rapport détaille la signature géochimique et spectrale du sillage ionique de la planète. L'analyse révèle un "échappement hydrodynamique chargé" de métaux lourds (Fer, Silicium), confirmant un volcanisme de friction permanent qui recycle la lithosphère en exosphère. Ces modélisations constituent un référentiel théorique "gelé" destiné à être confronté aux données d'observation du télescope James Webb (MIRI), marquant une étape clé dans l'étude de l'habitabilité post-géante rouge.
