Description
We present the K-correction for emission lines formed on the irradiated face of the companion stars in X-ray binaries. We compute this K-correction in a general approach as function of the mass ratio and the disc flaring angle. Our results combined with the detection of high energy emission lines arising from the donor star (e. g. Steeghs & Casares 2002 ; Hynes et al. 2003) can provide the most accurate mass determinations for either neutron stars or black holes in persistent Low Mass X-ray Binaries (LMXBs). The application of our model to X1822-371 (Munoz-Darias, Casares & Martinez-Pais 2005) strongly suggests the presence of a massive neutron star in this LMXB. Here, we also present the K-correction for the Black Hole binary GX339-4.

    The Aligned Orbit of a Hot Jupiter around the M Dwarf TOI-4201
    Measuring the obliquities of stars hosting giant planets may shed light on the dynamical history of planetary systems. Significant efforts have been made to measure the obliquities of FGK stars with hot Jupiters, mainly based on observations of the Rossiter–McLaughlin effect. In contrast, M dwarfs with hot Jupiters have hardly been explored because

    Einasto Gravitational Potentials have Difficulty to Hold Spherically Symmetric Stellar Systems with Cores
    It was known that an ideal spherically symmetric stellar system with isotropic velocities and an inner core cannot reside in a Navarro, Frenk, and White (NFW) gravitational potential. The incompatibility can be pinned down to the radial gradient of the NFW potential in the very center of the system, which differs from zero. The gradient is

    ROSALIA: ROman Sky Analyst for Low surface brightness Imaging & Astronomy
    Diffuse emission in the outskirts of galaxies, such as stellar tidal streams, galaxy stellar halos and intracluster light, provides important constraints on the structure and evolution of the Universe. However, such low surface brightness diffuse emission can be up to thousands of times dimmer (>29 AB mag/[square arcseconds]) than the sky
