MIGRATION OF PLANETS EMBEDDED IN A CIRCUMSTELLAR DISK [PDF]

open access: yesThe Astrophysical Journal, 2011
Planetary migration poses a serious challenge to theories of planet formation. In gaseous and planetesimal disks, migration can remove planets as quickly as they form. To explore migration in a planetesimal disk, we combine analytic and numerical approaches. After deriving general analytic migration rates for isolated planets, we use N-body simulations

Chemical History of Molecules in Circumstellar Disks [PDF]

open access: yesProceedings of the International Astronomical Union, 2011
AbstractThe chemical composition of a protoplanetary disk is determined not only by in situ chemical processes during the disk phase, but also by the history of the gas and dust before it accreted from the natal envelope. In order to understand the disk's chemical composition at the time of planet formation, especially in the midplane, one has to go ...

Processed and Unprocessed Ices in Circumstellar Disks [PDF]

open access: yesHighlights of Astronomy, 2005
AbstractWe present 3-5 µm VLT-ISAAC spectroscopy showing the presence of methanol ices in edge-on disks of young embedded stars. Examples include the disks of L1489 IRS in Taurus and CRBR 2422.8-3423 in Ophiuchus, the last of which has the highest column density of solid CO known toward a YSO.

Spectropolarimetry and the Study of Circumstellar Disks [PDF]

open access: yes, 2007
Circumstellar disks play an important role in many stages of the evolution of stars. However, it is only possible to directly image circumstellar disks for a few of the nearest stars. For massive stars, the situation is even more difficult, as they are on average further away than the more numerous low mass stars.
