Trumpler 20 - an old and rich open cluster

I. Platais, C. Melo, J. P. Fulbright +4

We show that the open cluster Trumpler 20, contrary to the earlier findings, is actually an old Galactic open cluster. New CCD photometry and high-resolution spectroscopy are used…

Resolving The ISM Surrounding GRBs with Afterglow Spectroscopy

Jason X. Prochaska, Hsiao-Wen Chen, Miroslava Dessauges-Zavadsky +1

We review current research related to spectroscopy of gamma-ray burst (GRB) afterglows with particular emphasis on the interstellar medium (ISM) of the galaxies hosting these high…

Evidence for metallicity spreads in three massive M31 globular clusters

Isaura Fuentes-Carrera, Pascale Jablonka, Ata Sarajedini +3

We quantify the intrinsic width of the red giant branches of three massive globular clusters in M31 in a search for metallicity spreads within these objects. We present HST/ACS obs…

The impact of stellar rotation on the CNO abundance patterns in the Milky Way at low metallicities

C. Chiappini, R. Hirschi, F. Matteucci +3

We investigate the effect of new stellar models, which take rotation into account, computed for very low metallicities on the chemical evolution of the earliest phases of the Milky…

A spectroscopic study of southern (candidate) gamma Doradus stars. I. Time series analysis

P. De Cat, L. Eyer, J. Cuypers +9

We present results of a spectroscopic study of 37 southern (candidate) gamma Doradus stars based on echelle spectra. The observed spectra were cross-correlated with the standard te…

A purely geometric distance to the binary star Atlas, a member of the Pleiades

N. Zwahlen, P. North, Y. Debernardi +4

We present radial velocity and new interferometric measurements of the double star Atlas, which permit, with the addition of published interferometric data, to precisely derive the…
