    On the Source of Propagating Slow Magnetoacoustic Waves in Sunspots
    Recent high-resolution observations of sunspot oscillations using simultaneously operated ground- and space-based telescopes reveal the intrinsic connection...
  • Publication
    On the Spatial Dependence of Low-Degree Solar p-Mode Frequency Shifts from Full-Disk and Resolved-Sun Observations
    We have analyzed low angular degree (low-l) solar p-mode frequency shifts extracted from two types of observations, both made by instruments on board the ESA...
  • Publication
    On the Spectroscopic Properties of Star-Forming Dwarf Galaxies in Different Environments
    A study is presented on the spectroscopic properties of a sample of star- forming dwarf galaxies in extreme density environments, as part of an ongoing project...
  • Publication
    On the Sr I λ4607 Å Hanle depolarization signals in the quiet Sun
    The Hanle depolarization signals of Sr i λ4607 Å have been used to estimate the unsigned magnetic flux and magnetic energy existing in the quiet Sun photosphere...
  • Publication
    On the Star Formation Efficiencies and Evolution of Multiple Stellar Generations in Globular Clusters
    By adopting empirical estimates of the helium enhancement (ΔY) between consecutive stellar generations for a sample of Galactic globular clusters (GGCs), we...
  • Publication
    On the Stellar Content of the Carina Dwarf Spheroidal Galaxy
    We present deep, accurate, and homogeneous multiband optical (U, B, V, I) photometry of the Carina dwarf spheroidal galaxy, based on more than 4000 individual...
  • Publication
    On the Stellar Content of the Starburst Galaxy IC10
    We investigate the stellar content of the starburst dwarf galaxy IC10 using accurate and deep optical data collected with the Advanced Camera for Surveys and...
  • Publication
    On the Stokes V Amplitude Ratio as an Indicator of the Field Strength in the Solar Internetwork
    The results of the determination of magnetic field strength from weak polarimetric signals in solar internetwork regions are contradictory. We investigate the...
  • Publication
    On the Storage of Magnetic Flux Tubes at the Base of the Solar Convection Zone
    The study of the storage of toroidal flux tubes at the base of the convection zone is of interest in connection with the operation of a solar αΩ-type dynamo...
