Title: CO variability in HAeBe disks: A search for planet-disk interactions
Abstract:
We propose to search for signatures of planets embedded in
protoplanetary disks by characterizing the variability of infrared CO
emission lines. This proposal directly bears on the ultimate question
in the study of planet formation - how do protoplanetary disk conditions
relate to the planetary systems that result? The quest to answer this
question would be greatly aided by the detection and characterization of
protoplanets and the disk environment in which they form, as well as by
the study of disk-planet interactions and resultant migration. However,
the detection of protoplanets by traditional planet-hunting methods is
hampered by the distance to star-forming regions and the variability of
young stars. In this study, we propose to search for CO line
variability that is expected to result from the interaction between
planets and their disks. CO line variability as well as disk
asymmetries on sub-AU scales have been detected in disks around low-mass
T Tauri stars. Here, we propose to extend the study of CO line
variability to disks around more massive Herbig Ae stars.
