The age of the Galactic thin disk from Th/Eu nucleocosmochronology III. Extended sample
E. F. del Peloso, L. da Silva, G. F. Porto de Mello +1
The first determination of the age of the Galactic thin disk from Th/Eu nucleocosmochronology was accomplished by us in Papers I and II. The present work aimed at reducing the age…
Ram pressure stripping of disk galaxies
E. Roediger, G. Hensler
(Abridged) We perform high resolution 2D hydrodynamical simulations of face-on ram pressure stripping (RPS) of disk galaxies to compile a comprehensive parameter study varying gala…
The age of the Galactic thin disk from Th/Eu nucleocosmochronology II. Chronological analysis
E. F. del Peloso, L. da Silva, L. I. Arany-Prado
The purpose of this work is to resume investigation of Galactic thin disk dating using nucleocosmochronology with Th/Eu stellar abundance ratios, a theme absent from the literature…
The age of the Galactic thin disk from Th/Eu nucleocosmochronology I. Determination of [Th/Eu] abundance ratios
E. F. del Peloso, L. da Silva, G. F. Porto de Mello
The purpose of this work is to resume investigation of Galactic thin disk dating using nucleocosmochronology with Th/Eu stellar abundance ratios, a theme absent from the literature…
The outflowing disks of B[e] supergiants and unclassified B[e] stars
Michaela Kraus, Marcelo Borges Fernandes
B[e] supergiants are known to possess outflowing cool disks but also some unclassified B[e] stars show clear indications for the presence of a neutral disk. We derive constraints o…
First results from the ATCA 18 GHz pilot survey
R. Ricci, E. M. Sadler, R. D. Ekers +7
As a pilot study for the first all-sky radio survey at short wavelengths, we have observed 1216 sq. deg. of the southern sky at 18GHz (16mm) using a novel wide-band (3.4GHz bandwid…
