Thermonuclear Accretion Disk Flash on a Compact Star

Full prompt

Astronomical digital artwork capturing a sudden runaway thermonuclear flash across the accretion disc of a compact star, composed in an impactful 1:1 square format for gallery showcase. Centered within the square frame, the compact core erupts in blinding brilliance, sending a searing radial blast wave sweeping symmetrically across swirling accretion lanes of deep crimson, incandescent amber, and electric cerulean. The shock wave violently shears the inner plasma disk into frothing, turbulent eddies that cast sharp specular rim light along outer spiral streamers. Siphoned stellar material from a companion star forms an illuminated spiral arm curving dynamically toward the perimeter. Rigorous depth of field and authentic physical light decay anchor the violent cataclysm within balanced square symmetry.
