    A Photometric and Kinematic Study of the Stars and Interstellar Medium in the Central 2 Kiloparsecs of NGC 3379
    Hubble Space Telescope images of NGC 3379 show that the V and I luminosity profiles in the inner 13" of this E1 galaxy are represented by two different...

    A Photometric Diagnostic to Aid in the Identification of Transiting Extrasolar Planets
    One of the obstacles in the search for exoplanets via transits is the large number of candidates that must be followed up, few of which ultimately prove to be...

    A Planet in a 0.6 AU Orbit Around the K0 Giant HD 102272
    We report the discovery of one or more planet-mass companions to the K0-giant HD 102272 with the Hobby-Eberly Telescope. In the absence of any correlation of...

    A Planetary Nebula around Nova V458 Vulpeculae Undergoing Flash Ionization
    Nova V458 Vul erupted on 2007 August 8 and reached a visual magnitude of 8.1 a few days later. Hα images obtained 6 weeks before the outburst as part of the...

    A Planetary-Mass Companion to the K0 Giant HD 17092
    We report the discovery of a substellar-mass companion to the K0 giant HD 17092 with the Hobby-Eberly Telescope. In the absence of any correlation of the...

    A Population of Dust-rich Quasars at z ~ 1.5
    We report Herschel SPIRE (250, 350, and 500 μm) detections of 32 quasars with redshifts 0.5

    A Possible Relationship between Quasars and Clusters of Galaxies
    The distribution on the sky of clusters of galaxies shows significant association with relatively nearby, large, active galaxies. The pattern is that of...

    A Possible Surviving Companion of the SN Ia in the Galactic SNR G272.2-3.2
    We use the Gaia EDR3 to explore the Galactic supernova remnant (SNR) G272.2-3.2, produced by the explosion of a Type Ia supernova (SN Ia) about 7500 yr ago, to...

    A Precessing Collimated Outflow in the Quadrupolar Planetary Nebula NGC 6881
    We present high-quality (subarcsecond) optical narrowband CCD images of the planetary nebula NGC 6881, which reveal a highly collimated bipolar structure. A...
