    The Incompatibility of Rapid Rotation with Narrow Photospheric X-Ray Lines in Exo 0748-676 by Lin, Jinrong, Ozel, Feryal, Chakrabarty, Deepto, Psaltis, Dimitrios

    Published 2013
    “…X-ray observations of EXO 0748–676 during thermonuclear bursts revealed a set of narrow (Δλ/λ = 0.018) absorption lines that potentially originate from the stellar photosphere. The identification of these lines with particular atomic transitions led to the measurement of the surface gravitational redshift of the neutron star and to constraints on its mass and radius. …”

    Photospheric Velocity Evolution of SN 2020bvc: Signature of r-process Nucleosynthesis from a Collapsar by Long Li, Shu-Qing Zhong, Zi-Gao Dai

    Published 2023-01-01
    “…Based on semi-analytic SN emission models with and without r -process materials, we perform a fitting to the multiband light curves and photospheric velocities of SN 2020bvc. We find that in a r -process-enriched model the mixing of r -process materials slows down the photospheric recession and therefore matches the velocity evolution better. …”
