On the Absolute Age of the Globular Cluster M92
We present precise and deep optical photometry of the globular M92. Data were collected in three different photometric systems: Sloan Digital Sky Survey (g ', r...
On the Absolute Age of the Metal-rich Globular M71 (NGC 6838). I. Optical Photometry
We investigated the absolute age of the Galactic globular cluster M71 (NGC 6838) using optical ground-based images (u\prime ,g\prime ,r\prime ,i\prime ,z\prime...
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 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...
On the anticorrelation between pericentric distance and inner dark matter density of Milky Way's dwarf spheroidal galaxies
An anticorrelation between the central density of the dark matter (DM) halo (ρ 150, DM) and the pericentric distances (r p) of the Milky Way's (MW's) dwarf...
On the C60 Fullerene Adduct with Pentacene: Synthesis and Stability
C60 fullerene and pentacene were reacted under mild conditions in toluene, yielding the monoadduct, which was characterized by electronic absorption and Fourier...
On the Central Helium-burning Variable Stars of the LeoI Dwarf Spheroidal Galaxy
We present a study of short-period, central helium-burning variable stars in the Local Group dwarf spheroidal galaxy LeoI, including 106 RR Lyrae stars and 51...
On the Chemical Abundances of Miras in Clusters: V1 in the Metal-rich Globular NGC 5927
We present the first spectroscopic abundance determination of iron, α-elements (Si, Ca, and Ti), and sodium for the Mira variable V1 in the metal-rich globular...
On the Density Profile of the Globular Cluster M92
We present new number density and surface brightness profiles for the globular cluster M92 (NGC 6341). These profiles are calculated from optical images...
