Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. V. Evidence for a wide age distribution and a complex MDF
T. Bensby, J. C. Yee, S. Feltzing +20
Based on high-resolution spectra obtained during gravitational microlensing events we present a detailed elemental abundance analysis of 32 dwarf and subgiant stars in the Galactic…
Disc formation in turbulent cloud cores: is magnetic flux loss necessary to stop the magnetic braking catastrophe or not?
R. Santos-Lima, E. M. de Gouveia Dal Pino, A. Lazarian
Recent numerical analysis of Keplerian disk formation in turbulent, magnetized cloud cores by Santos-Lima, de Gouveia Dal Pino, & Lazarian (2012) demonstrated that reconnection dif…
SgrA* emission at 7mm: variability and periodicity
Pedro Paulo B. Beaklini, Zulema Abraham
We present the result of 6 years monitoring of SgrA*, radio source associated to the supermassive black hole at the centre of the Milky Way. Single dish observations were performed…
Barium Abundances in Cepheids
S. M. Andrievsky, J. R. D. Lepine, S. A. Korotin +3
We derived the barium atmospheric abundances for a large sample of Cepheids, comprising 270 stars. The sample covers a large range of galactocentric distances, from about 4 to 15 k…
Characterization of Young Stellar Clusters
T. Santos-Silva, J. Gregorio-Hetem
A high number of embedded clusters is found in the Galaxy. Depending on the formation scenario, most of them can evolve to unbounded groups that are dissolved within a few tens of…
Milky Way demographics with the VVV survey. I. The 84-million star colour-magnitude diagram of the Galactic bulge
R. K. Saito, D. Minniti, B. Dias +9
The Milky Way (MW) bulge is a fundamental Galactic component for understanding the formation and evolution of galaxies, in particular our own. The ESO Public Survey VISTA Variables…
Molecular chemistry and the missing mass problem in PNe
Rafael K. Kimura, Ruth Gruenwald, Isabel Aleman
Detections of molecular lines, mainly from H2$ and CO, reveal molecular material in planetary nebulae. Observations of a variety of molecules suggest that the molecular composition…
The Interstellar Magnetic Field Close to the Sun II
P. C. Frisch, B-G Andersson, A. Berdyugin +9
A key indicator of the galactic environment of the Sun is provided by the magnetic field in the interstellar medium (ISM), which influences the shape of the heliosphere. The direct…
Acceleration of Energetic Particles through Reconnection of Weakly Stochastic Magnetic Field
A. Lazarian, G. Kowal, E. Gouveia dal Pino +1
Astrophysical media are turbulent and therefore reconnection should be treated in the presence of pre-existing turbulence. We consider the model of fast magnetic reconnection in La…
The young stellar cluster [DBS2003] 157 associated with the H II region GAL 331.31-00.34
Marcio C. Pinheiro, Zulema Abraham, Marcus V. F. Copetti +3
We report a study of the stellar content of the Near-infrared cluster [DBS2003]\,157 embedded in the extended H\,{\sc ii} region GAL\,331.31-00.34, which is associated with the IRA…
Homogeneous Metallicities and Radial Velocities for Galactic Globular Clusters
Ivo Saviane, Gary S. Da Costa, Enrico V. Held +4
Well determined radial velocities and abundances are essential for analyzing the properties of the Globular Cluster system of the Milky Way. However more than 50% of these clusters…
Signatures of an intermediate-age metal-rich bulge population
T. Bensby, S. Feltzing, A. Gould +8
We have determined detailed elemental abundances and stellar ages for a sample of now 38 microlensed dwarf and subgiant stars in the Galactic bulge. Stars with sub-solar metallicit…
The Globular Cluster Kinematics and Galaxy Dark Matter Content of NGC 3923
Mark A. Norris, Karl Gebhardt, Ray M. Sharples +9
This paper presents further results from our spectroscopic study of the globular cluster (GC) system of the group elliptical NGC 3923. From observations made with the GMOS instrume…
