Description
The off-centered bar and its single spiral arm are the most defining morphological features of the Large Magellanic Cloud (LMC), prototype of the Magellanic Spirals. Fortunately, its proximity and the quality of the colour-magnitude diagrams from SMASH allow an unprecedented characterisation of its stellar populations covering its whole extension. Such characterisation shows compelling evidence supporting the long-term stability of the LMC spiral arm, dating its origin to at least 2 Gyr ago, linked with the close LMC-SMC encounter that produced the gaseous Magellanic Stream and its Leading Arm.

    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

    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

    A Systematic Search for and Characterization of White Dwarf Binaries Across the H-R Diagram
    White dwarfs (WDs) are the endpoint of evolution for 97% of stars. Most of these stars are in multiple systems, and a significant fraction of those are compact enough to exchange mass, altering the structures and subsequent evolution of both stars. The physical mechanisms that facilitate these mass exchanges include common envelope evolution, Roche
