Description
GRO J1744-28, AKA "The Bursting Pulsar", first discovered in 1995 by the Compton Gamma-Ray Observatory, has lay dormant since its 2nd outburst in 1996. On January 18th, 2014, it was detected again by Swift's Burst Alert Telescope and by the Japanese MAXI scanning X-ray telescope. Swift's BAT triggered many times on the bright bursts seen from GRO J1744-28 during this latest outburst, and detected over 600 bursts. The reappearance of this exciting transient triggered a high cadence monitoring program by Swift/XRT to provide flux, timing and spectral coverage of the entire outburst. Here we report on these observations of this new outburst by Swift's BAT and XRT, including analysis of burst rates, periodicity and pulse profile. We also show the spectral evolution of the source as seen by Swift/XRT throughout the latest outburst.

    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
