Detection of the high z GRB 080913 and its implications on progenitors and energy extraction mechanisms
D. Perez-Ramirez, A. de Ugarte Postigo, J. Gorosabel +15
Aims: We present multiwavelength observations of one of the most distant gamma-ray bursts detected so far, GRB 080913. Based on these observations, we consider whether it could be…
Optical and infrared flares from a transient Galactic soft gamma-ray repeater
A. J. Castro-Tirado, A. de Ugarte Postigo, J. Gorosabel +33
Soft gamma-ray repeaters (SGRs) are a rare type of gamma-ray transient sources that are ocasionally detected as bursts in the high-energy sky. They are thought to be produced by ma…
HI and CO in the circumstellar environment of the oxygen-rich AGB star RX Lep
Y. Libert, T. Le Bertre, E. Gérard +1
Circumstellar shells around AGB stars are built over long periods of time that may reach several million years. They may therefore be extended over large sizes (~1 pc, possibly mor…
Dust-driven Winds and Mass Loss of C-rich AGB Stars with subsolar Metallicities
A. Wachter, J. M. Winters, K. -P. Schröder +1
We investigate the mass loss of highly evolved, low- and intermediate mass stars and stellar samples with subsolar metallicity. We give a qualitative as well as quantitative descri…
