Descripción
The GTC Adaptive Optics (GTCAO) system will provide diffraction-limited capabilities in the near infrared to the GTC telescope. At first, it will use a Natural Guide Star (NGS) as a reference source, and later it will be upgraded to a Sodium Laser Guide Star (LGS), which will significantly increase the sky coverage. The GTCAO system is expected to provide a strehl ratio of 0.65 in the K-band with a bright NGS and a minimum strehl ratio of 0.1 with the LGS using a tip-tilt star brighter than 18 mag. We will review the current status of the performance tests of the GTCAO system in the IAC laboratory, and present the development of the LGS system at the IAC, which is currently in the detailed design phase.

    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
