The primordial abundance of 4He, YP, is one of the hottest themes in present-day astronomy, mostly due to its cosmological relevance. The disagreement between...
The Pristine Inner Galaxy Survey (PIGS) V: a chemo-dynamical investigation of the early assembly of the Milky Way with the most metal-poor stars in the bulge
The investigation of the metal-poor tail in the Galactic bulge provides unique information on the early Milky Way assembly and evolution. A chemo-dynamical...
The process $mu o
u_{e}ear{
u}_{mu} $in the 2HDM with flavor changing neutral currents
We consider the process $mu o u_{e}ear{ u}_{mu} $in the framework of a two Higgs doublet model with flavor changing neutral currents (FCNC). Since FCNC...

The profuse optically-thin irregularities of the photospheric magnetic fields
The highly irregular nature of most photospheric magnetic fields is analyzed here, trying to emphasize the connection between photospheric fluctuations and...
The promise of Bayesian analysis for prominence seismology
We propose and use Bayesian techniques for the determination of physical parameters in solar prominence plasmas, combining observational and theoretical...
The photometric and kinematic properties of Sb NGC 1292 suggest it hosts a pseudobulge. The properties of the stellar population of such a pseudobulge are...
The PSU/TCfA search for planets around evolved stars. Stellar parameters and activity indicators of targets.
The main objective of the Penn State/Toruń Centre for Astronomy search for planets around evolved stars is the detection of planetary systems around massive...
