We have obtained high-resolution echelle spectroscopy of the recurrent nova T CrB. We find that the surface lithium abundance in T CrB is significantly enhanced...
On the accretion of a new group of galaxies on to Virgo - II. The effect of pre-processing on the stellar population content of dEs
Using MUSE spectra, we investigate how pre-processing and accretion on to a galaxy cluster affect the integrated stellar population properties of dwarf early...
On the accretion of a new group of galaxies on to Virgo: I. Internal kinematics of nine in-falling dEs
Galaxy environment has been shown to play an important role in transforming late-type, star-forming galaxies to quiescent spheroids. This transformation is...
On the accretion of a new group of galaxies onto Virgo - III. The stellar population radial gradients of dEs
Using MUSE data, we investigate the radial gradients of stellar population properties (namely age, [M/H], and the abundance ratio of α elements [α/Fe]) for a...
Full solar disk observations of radial velocity, obtained with the IRIS network of resonant scattering spectrometers, are used to analyze the acoustic p-mode...
On the action of UV photons on hydrogenated fulleranes C60H36 and C60D36
Fulleranes, the hydrogenated fullerenes C60H36 and C60D36 have been synthesized in n-hexane where they show an absorption maximum at 217 nm in their electronic...
On the age dependence of the asymmetry of penumbrae of sunspot
The age dependence of the recently described asymmetry of penumbrae of large stable sunspots was analyzed. Young sunspots showed shorter eastern penumbrae...
Results of photometric surveys have brought to light the existence of a population of giant planets orbiting their host stars even closer than the hot Jupiters...
On the alumina dust production in the winds of O-rich asymptotic giant branch stars
The O-rich asymptotic giant branch (AGB) stars experience strong mass-loss with efficient dust condensation and they are major sources of dust in the...
