    Surface Alfvén Waves in Solar Flux Tubes
    Magnetohydrodynamic (MHD) waves are ubiquitous in the solar atmosphere. Alfvén waves and magneto-sonic waves are particular classes of MHD waves. These wave...

    Surface Brightness and Stellar Populations at the Outer Edge of the Large Magellanic Cloud: No Stellar Halo Yet
    We present a high-quality color-magnitude diagram (CMD) for a 36'×36' field located 8° (~=7 kpc) from the Large Magellanic Cloud (LMC) center, as well as a...

    Surges and Si IV Bursts in the Solar Atmosphere: Understanding IRIS and SST Observations through RMHD Experiments
    Surges often appear as a result of the emergence of magnetized plasma from the solar interior. Traditionally, they are observed in chromospheric lines such as...

    SWIFT J1753.5-0127: A Surprising Optical/X-Ray Cross-Correlation Function
    We have conducted simultaneous optical and X-ray observations of SWIFT J1753.5-0127 with RXTE and ULTRACAM, while the system persisted in its relatively bright...

    Swift J1753.5-0127: The Black Hole Candidate with the Shortest Orbital Period
    We present time-resolved photometry of the optical counterpart to the black hole candidate Swift J1753.5-0127 which has remained in the low/hard X-ray state and...

    Symbiotic Stars in the Apache Point Observatory Galactic Evolution Experiment Survey: The Case of LIN 358 and SMC N73 (LIN 445a)
    LIN 358 and SMC N73 are two symbiotic binaries in the halo of the Small Magellanic Cloud, each composed of a hot white dwarf accreting from a cool giant...

    Synthetic Observations of Wave Propagation in a Sunspot Umbra
    Spectropolarimetric temporal series from Fe I λ6301.5 Å and Ca II infrared triplet lines are obtained by applying the Stokes synthesis code NICOLE to a...

    Systematic Redshift of the Fe III UV Lines in Quasars: Measuring Supermassive Black Hole Masses under the Gravitational Redshift Hypothesis
    We find that the Fe III λλ2039-2113 spectral feature in quasars appears systematically redshifted by amounts accountable under the hypothesis of gravitational...

    Systematic Search for Extremely Metal-poor Galaxies in the Sloan Digital Sky Survey
    We carry out a systematic search for extremely metal-poor (XMP) galaxies in the spectroscopic sample of Sloan Digital Sky Survey (SDSS) data release 7 (DR7)...
