Description
The study of δ Scuti stars in a cluster allows to consider that all the objects have the same age, chemical composition and distance. In addition to this, the parameters like metallicity or distance are better estimated for stars belonging to a cluster than for typical field stars. We consider here a set of four Delta Scuti stars in the Pleiades cluster, observed in recent multi-site networks. We have calculated rotating stellar models with input physics appropriate to the star and cluster parameters. We have computed the adiabatic oscillation eigenfrequencies of the stellar models, up to second order in the rotational rate. A range of modes for each Delta Scuti star is presented.

    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
