    A second-order approximation to equatorial null geodesics in the Kerr metric - Application to light deflection in eclipsing compact binaries
    We present a second-order analytical expansion of null equatorial geodesics in the Kerr metric. The equations developed are applied to the study of light...

    Double-lined Spectroscopic Binaries in the APOGEE DR16 and DR17 Data
    APOGEE spectra offer ≲1 km s -1 precision in the measurement of stellar radial velocities. This holds even when multiple stars are captured in the same spectrum...
