Millimeter and submillimeter high angular resolution interferometric observations: dust in the heart of IRAS 18162-2048
circumstellar matter — ISM individual (GGD27, HH 80-81 IRAS 18162-2048)— stars
2010/11/12
The GGD27 complex includes the HH 80-81-80N system, which is one of the most powerful molecular outflows associated with a high mass star-forming region observed up to now. This outflow is powered by ...
Fermi Gamma-ray Space Telescope: High-Energy Results from the First Year
Fermi Gamma-ray Space Telescope High-Energy Results
2010/11/9
The Fermi Gamma-ray Space Telescope (Fermi) was launched on June 11, 2008 and began its
first year sky survey on August 11, 2008. The Large Area Telescope (LAT), a wide field-ofview
pair-conversion ...
Magnetic field structure in a high-mass outflow/disk system
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
To characterize the magnetic field structure of the outflow and core region within a prototypical high-mass star-forming region, we analyzed polarized CO(3-2) - for the first time observed with the Su...
High-angular resolution observations of the Pistol Star
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
First results of near-IR adaptive optics (AO)-assisted imaging, interferometry, and spectroscopy of this Luminous Blue Variable (LBV) are presented. They suggest that the Pistol Star is at least doubl...
Observational approach to the chemical evolution of high-mass binaries
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
The complexity of composite spectra of close binaries makes the study of the individual stellar spectra extremely difficult. For this reason there exists very little information on the chemical compos...
High Velocity Molecular Outflows In Massive Cluster Forming Region G10.6-0.4
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/4
We report the arcsecond resolution SMA observations of the $^{12}$CO (2-1) transition in the massive cluster forming region G10.6-0.4. In these observations, the high velocity $^{12}$CO emission is re...
HERMES: a high-resolution fibre-fed spectrograph for the Mercator telescope
Instrumentation spectrographs Techniques spectroscopic Techniques radial velocities Stars: abundances
2010/11/9
The HERMES high-resolution spectrograph project aims at exploiting the specific potential of small but flexible telescopes in observational astrophysics. The optimised optical design of the spectrogra...
HerMES : SPIRE detection of high redshift massive compact galaxies in GOODS-N field
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We have analysed the rest-frame far infrared (FIR) properties of a sample of massive (Mstar > 10^11Msun) galaxies at 2igins Deep Survey) North field using the ...
