New estimates of the contribution of Wolf--Rayet stellar winds to the Galactic 26Al
A. Palacios, G. Meynet, C. Vuissoz +4
We present new yields of 26Al from Wolf--Rayet stellar winds based on rotating stellar models which account well for numerous observed properties of massive stars. We study the imp…
Systematic Search for Short-transients and Pulsation Events from INTEGRAL Survey Data
Ken Ebisawa, Peter Kretschmar, Nami Mowlavi +9
The imaging instruments on board INTEGRAL have wide fields of view and high time resolution. Therefore, they are ideal instruments to search for pulsating sources and/or transient…
Scientific Performance of the ISDC Quick Look Analysis
S. E. Shaw, N. Mowlavi, K. Ebisawa +22
The INTEGRAL Science Data Centre (ISDC) routinely monitors the Near Real Time data (NRT) from the INTEGRAL satellite. A first scientific analysis is made in order to check for the…
The Geneva-Copenhagen survey of the Solar neighbourhood: Ages, metallicities, and kinematic properties of 14,000 F and G dwarfs
B. Nordstrom, M. Mayor, J. Andersen +6
We present and discuss new determinations of metallicity, rotation, age, kinematics, and Galactic orbits for a complete, magnitude-limited, and kinematically unbiased sample of 16,…
Al(26) Studies with INTEGRAL's Spectrometer SPI
R. Diehl, K. Kretschmer, G. Lichti +13
Al(26) radioactivity traces recent nucleosynthesis throughout the Galaxy, and is known to be produced in massive stars and novae. The map from its decay gamma-ray line suggests mas…
