    PG 1553+113: Five Years of Observations with MAGIC
    We present the results of five years (2005-2009) of MAGIC observations of the BL Lac object PG 1553+113 at very high energies (VHEs; E > 100 GeV). Power-law...

    Phase Differences and Gains between Intensity and Velocity in Low-Degree Acoustic Modes Measured by SOHO
    Helioseismic instruments aboard SOHO are making possible a more accurate way of investigating the internal structure of the Sun. Making use of the different...

    Phase-dependent Study of Near-infrared Disk Emission Lines in LB-1
    The mass, origin, and evolutionary stage of the binary system LB-1 have been intensely debated, following the claim that it hosts an ∼70M ☉ black hole, in stark...

    Photoevaporating Flows from the Cometary Knots in the Helix Nebula (NGC 7293)
    We explain the Hα emission of the cometary knots in the Helix Nebula (NGC 7293) with an analytical model that describes the emission of the head of the globules...

    Photoionization Models of NGC 2363 and Their Implications for the Ionizing Star Cluster
    Using the photoionization code CLOUDY, we compute photoionization models for the giant extragalactic H II region NGC 2363 and compare them with optical...

    Photoionization Models of NGC 346
    We present spherically symmetric and plane-parallel photoionization models of NGC 346, an H II region in the Small Magellanic Cloud. The models are based on...

    Photometric Amplitude Distribution of Stellar Rotation of KOIs—Indication for Spin-Orbit Alignment of Cool Stars and High Obliquity for Hot Stars
    The observed amplitude of the rotational photometric modulation of a star with spots should depend on the inclination of its rotational axis relative to our...
