CIRCUMSTELLAR STRUCTURE AROUND EVOLVED STARS IN THE CYGNUS-X STAR FORMATION REGION
Cygnus-X star MIPS IRAC
2014/12/22
We present observations of newly discovered 24 micron circumstellar structures detected with the Multiband Imaging Photometer for Spitzer (MIPS) around three evolved stars in the Cygnus-X star forming...
Circumstellar gas and dust emission and mass loss from evolved stars
Orbiting a star Gas Dust emissions Evolution of stars
2014/12/9
This dissertation presents a study of the circumstellar gas and dust emission and their relation to the mass-loss in evolved stars. Considering the physical process of heating and cooling of the dust,...
Mid-infrared interferometric monitoring of evolved stars - The dust shell around the Mira variable RR Aql at 13 epochs
Techniques:interferometric – Stars:AGB – Stars:atmospheres – Stars:mass loss – Stars:individual:RR Aql
2011/9/28
We obtained 13 epochs of mid-infrared interferometry with the MIDI instrument at the VLTI between April 2004 and July 2007, covering pulsation phases 0.45-0.85 within four cycles. The data are modeled...
Observations of dusty torii and compact disks around evolved stars: the high spatial resolution IR view
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
The recent high angular resolution observations have shown that the transition between a globally symmetrical giant and a source surrounded by a spatially complex environment occurs relatively early, ...
