    A Preliminary Budget for the Ionizing Photons in HII Regions of M51
    The purpose of this work is to quantify the ionizing photon budget in the HII regions, deriving the fraction of the Lyman continuum (Lyc) absorbed by dust or...

    A Preliminary Budget for the Ionizing Photons in the H II Regions of M51
    Using HST/ACS broad- and narrow-band (Hα) images of M51 we have examined the ionizing radiation budget in a set of luminous H II regions in a spiral arm between...

    A preliminary comparison of observed and theoretical frequencies for some Delta Scuti stars on the Pleiades cluster
    The study of δ Scuti stars in a cluster allows to consider that all the objects have the same age, chemical composition and distance. In addition to this, the...

    A probabilistic formulation of evolutionary synthesis models: implications for SED fittings
    Evolutionary synthesis models (ESM) have been extensively used to obtain the star formation history in galaxies by means of SED fitting. Implicit in this use of...

    A probability distribution for the amplitude of Solar Cycle 25
    We suggest a method to calculate the probability for the maximum amplitude of Solar Cycle 25 using Bayesian inference. We illustrate this approach with the...

    A prototype for the PASS Permanent All Sky Survey
    A prototype system for the Permanent All Sky Survey (PASS) project is presented. PASS is a continuous photometric survey of the entire celestial sphere with a...

    A Puzzling Li-rich Red Giant in the APOGEE Field
    We report on a spectroscopic study of the unusual Li-rich red giant (RG) recently discovered in NGC 6819. This star was observed by the Apache Point Observatory...
