    The Effective Temperatures of Mid-O Stars
    We derived photospheric parameters, mass-loss rates, and wind velocities of Galactic O6-O7 stars by analyzing high-resolution spectra in the far-UV and UV...

    The Effects of Magnetic-field Geometry on Longitudinal Oscillations of Solar Prominences
    We investigate the influence of the geometry of the solar filament magnetic structure on the large-amplitude longitudinal oscillations. A representative...

    The Effects of Three-dimensional Radiative Transfer on the Resonance Polarization of the Ca I 4227 Å Line
    The sizable linear polarization signals produced by the scattering of anisotropic radiation in the core of the Ca I 4227 Å line constitute an important...

    The Einstein Cross: Constraint on Dark Matter from Stellar Dynamics and Gravitational Lensing
    We present two-dimensional line-of-sight stellar kinematics of the lens galaxy in the Einstein Cross, obtained with the GEMINI 8 m telescope, using the GMOS...

    The Einstein Probe Transient EP240414a: Linking Fast X-Ray Transients, Gamma-Ray Bursts, and Luminous Fast Blue Optical Transients
    Detections of fast X-ray transients (FXTs) have accrued over the last few decades. However, their origin has remained mysterious. Rapid progress is now being...

    The Einstein Ring GAL-CLUS-022058s: a Lensed Ultrabright Submillimeter Galaxy at z = 1.4796
    We report an ultrabright lensed submillimeter galaxy at z spec = 1.4796, identified as a result of a full-sky cross-correlation of the AllWISE and Planck...

    The ELM Survey. II. Twelve Binary White Dwarf Merger Systems
    We describe new radial velocity and X-ray observations of extremely low-mass white dwarfs (ELM WDs, ~0.2 M sun) in the Sloan Digital Sky Survey Data Release 4...

    The ELM Survey. III. A Successful Targeted Survey for Extremely Low Mass White Dwarfs
    Extremely low mass (ELM) white dwarfs (WDs) with masses 0.25 M &sun; are rare objects that result from compact binary evolution. Here, we present a targeted...
