A high-resolution line survey of IRC +10216 with Herschel/HIFI *,** First results: Detection of warm silicon dicarbide (SiC)
carbon-rich evolved star IRC+10216
2014/12/20
We present the first results of a high-spectral-resolution survey of the carbon-rich evolved star IRC+10216 that was carried out with the HIFI spectrometer onboard Herschel. This survey covers all HIF...
Emission line diagnostics of magnetospheric accretion in young stellar objects
Line emission Stars Accretion Star formation Formation of the accretion flow Stars Magnetic layer
2014/12/9
This thesis seeks to explain the nature of line emission observed in young stellar objects, and to use the lines as diagnostics of the accretion process that is central to star formation. We maintain ...
Star formation in self-gravitating disks in active galactic nuclei. I. Metallicity gradients in broad line regions
Star formation self-gravitating disks active galactic Metallicity gradients
2011/10/11
It has been suggested that the high metallicity generally observed in active galactic nuclei (AGNs) and quasars originates from ongoing star formation in the self-gravitating part of accretion disks a...
An international team of astrophysicists has mapped the borderlands between two of our neighbouring galaxies to reveal an ongoing galactic jostle that will eventually result in the formation of one su...
