    Evidence for Population-dependent Vertical Motions and the Long-lived Nonsteady Lopsided Milky Way Warp
    We present a Galactic disk vertical velocity analysis using OB type stars (OB stars), red clump (RC) stars, and main-sequence turnoff (MSTO) stars with...

    Evidence for Quasi-Isotropic Magnetic Fields from Hinode Quiet-Sun Observations
    Some recent investigations of spectropolarimetric observations of the Zeeman effect in the Fe I lines at 630 nm carried out with the Hinode solar space...

    Evidence for Spin─Orbit Alignment in the TRAPPIST-1 System
    In an effort to measure the Rossiter─McLaughlin effect for the TRAPPIST-1 system, we performed high-resolution spectroscopy during transits of planets e, f, and...

    Evidence for the Accretion of Gas in Star-forming Galaxies: High N/O Abundances in Regions of Anomalously Low Metallicity
    While all models for the evolution of galaxies require the accretion of gas to sustain their growth via on-going star formation, it has proven difficult to...

    Evidence for the Naphthalene Cation in a Region of the Interstellar Medium with Anomalous Microwave Emission
    We report high-resolution spectroscopy of the moderately reddened (AV=3) early-type star Cernis 52 located in a region of the Perseus molecular cloud complex...

    Evidence for the Operation of the Hanle and Magneto-optical Effects in the Scattering Polarization Signals Observed by CLASP2 across the Mg II h and k Lines
    Radiative transfer investigations of the solar Mg II h and k resonance lines around 280 nm have shown that, while their circular polarization (Stokes V) signals...

    Evidence for TiO in the Atmosphere of the Hot Jupiter HAT-P-65 b
    We present the low-resolution transmission spectra of the puffy hot Jupiter HAT-P-65b (0.53 M Jup, 1.89 R Jup, T eq = 1930 K), based on two transits observed...

    Evidence of a Black Hole in the X-Ray Transient GS 1354-64 (=BW Circini)
    We present the first radial velocity curve of the companion star to BW Cir that demonstrates the presence of a black hole in this X-ray transient that recorded...

    Evidence of Magnetic Accretion in an SW Sextantis Star: Discovery of Variable Circular Polarization in LS Pegasi
    We report on the discovery of variable circular polarization in the SW Sextantis star LS Pegasi. The observed modulation has an amplitude of ~0.3% and a period...
