The generally adopted value for the solar abundance of indium is over six times higher than the meteoritic value. We address this discrepancy through numerical...
On the Solar Origin of the Signal at 220.7 μHz: A Possible Component of a g-Mode?
Gravity modes in the Sun have been the object of a long and difficult search in recent decades. Thanks to the data accumulated with the last generation of...
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...
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...
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...
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...
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...
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...
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...
