We obtain the first image of a parity-odd celestial body. Recently, an intriguing parity-odd rotating boson star was proposed. We investigate the lensing effects of these stars in detail. Our analysis demonstrates distinct gravitational distortions around these stars, clearly differentiating them from their parity-even counterparts. Furthermore, we analyze the conditions under which chaotic behavior appears in the images of ultra-compact stars.

  1. Broadened Lensing Rings of Compact Boson Stars: Enhanced Imprint of Accretion Flow in Images and Visibilities

    astro-ph.HE 2026-06 unverdicted novelty 5.0 of 10

    Compact boson stars exhibit broader gravitational lensing rings than black holes, resulting in images and visibilities that depend more strongly on the structure of the accretion flow.

  2. Distorting Kerr Images with Parity-Odd Scalar Hair

    gr-qc 2026-05 unverdicted novelty 5.0 of 10

    Numerical study of thin accretion disk images shows that increasing parity-odd scalar hair on Kerr black holes shrinks and distorts the photon ring and shadow, producing multiple disconnected shadows and chaotic lensi...

  3. Beyond general relativity: gravitational waves in non-minimally coupled theories

    gr-qc 2025-10 conditional novelty 5.0 of 10

    A generalized propagation parameterization for gravitational-wave strains is extended to O(H²) and O(H′), then mapped to Kalb-Ramond, axion-dilaton–Chern-Simons–Gauss-Bonnet, and U(1) dark-photon models.

  4. Semi-analytical Study on the Polarized Images of Black Hole due to Frame Dragging

    gr-qc 2025-08 unverdicted novelty 5.0 of 10

    Frame dragging flips an initially retrograde equatorial flow around a Kerr black hole, and the polarized image shows three distinct critical locations whose spatial hierarchy is derived analytically for an on-axis observer.

  5. Light Rings, Accretion Disks and Shadows of Hayward Boson Stars

    gr-qc 2025-07 unverdicted novelty 5.0 of 10

    Numerical construction of Hayward boson stars shows that frozen states produce Schwarzschild-like shadows with no extra photon rings while non-frozen states show multiple photon rings inside the shadow.
