Description
The X17.0 solar flare of September 07, 2005 released high-energy neutrons, that were detected by the Solar Neutron Telescope (SNT) at Sierra Negra, Mexico. In two separate and independent studies of this solar neutron event, the energy spectra as a power law was calculated ( Sako, T., et al., 2006, ApJ, 651, 69. Watanabe, K., et al., 2006. ApJ, 636, 1135) In this paper, we show an alternative analysis, based on an improved numerical simulations of the detector using GEANT 4, and a different technique to treat the SNT data. The results indicate that the spectral index which best fits the neutron flux is nearly 3, in agreement with previous works. Based in the numerically calculated energy deposition of SNT, we confirm that neutrons were detected with at least 1GeV, which implies that the solar flare might have produced 10GeV protons; these could not be observed at Earth, as the source flare was in the east limb of the Sun.

    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
