    Penumbral thermal structure below the visible surface
    Context. The thermal structure of the penumbra below its visible surface (i.e., τ5 ≥ 1) has important implications for our present understanding of sunspots and...

    PEP: First Herschel probe of dusty galaxy evolution up to z ~ 3
    Aims: We exploit the deepest existing far-infrared (FIR) data obtained so far by Herschel at 100 and 160 μm in the GOODS-N, as part of the PACS evolutionary...

    Performance of solar far-side active region neural detection
    Context. Far-side helioseismology is a technique used to infer the presence of active regions in the far hemisphere of the Sun based on the interpretation of...

    Period, epoch, and prediction errors of ephemerides from continuous sets of timing measurements
    Space missions such as Kepler and CoRoT have led to large numbers of eclipse or transit measurements in nearly continuous time series. This paper shows how to...

    Periodic mass-loss episodes due to an oscillation mode with variable amplitude in the hot supergiant HD 50064
    Aims: We aim to interpret the photometric and spectroscopic variability of the luminous blue variable supergiant HD 50064 (V = 8.21). Methods: CoRoT space...

    Persistent magnetic vortex flow at a supergranular vertex
    Context. Photospheric vortex flows are thought to play a key role in the evolution of magnetic fields. Recent studies show that these swirling motions are...

    PG 1618+563B: A new bright pulsating sdB star
    The results of two runs of time-series photometry made at the Nordic Optical Telescope clearly show that the sdB star PG 1618+563B is a new member of the EC...

    PG 1657+416: a new fast pulsating sdB star. Photometric observations and theoretical model comparison
    Context: Since the discovery in 1997 of stellar oscillations in some B-type hot subdwarfs (sdBs), much effort is being made both observationally and...
