Transition disk chemistry and future prospects with ALMA
L. Ilsedore Cleeves, Edwin A. Bergin, Thomas J. Bethell +4
We explore the chemical structure of a disk that contains a large central gap of R ~ 45 AU, as is commonly seen in transitional disk systems. In our chemical model of a disk with a…
Detection of the Water Reservoir in a Forming Planetary System
Michiel R. Hogerheijde, Edwin A. Bergin, Christian Brinch +12
Icy bodies may have delivered the oceans to the early Earth, yet little is known about water in the ice-dominated regions of extra-solar planet-forming disks. The Heterodyne Instru…
Disk Imaging Survey of Chemistry with SMA: II. Southern Sky Protoplanetary Disk Data and Full Sample Statistics
Karin I. Oberg, Chunhua Qi, Jeffrey K. J. Fogel +6
This is the second in a series of papers based on data from DISCS, a Submillimeter Array observing program aimed at spatially and spectrally resolving the chemical composition of 1…
Gemini GMOS spectroscopy of HeII nebulae in M33
C. Kehrig, M. S. Oey, P. A. Crowther +6
We have carried out a narrow-band survey of the Local Group galaxy, M33, in the HeII4686 emission line, to identify HeII nebulae in this galaxy. With spectroscopic follow-up observ…
Chemistry of a protoplanetary disk with grain settling and Lyman alpha radiation
Jeffrey K. J. Fogel, Thomas J. Bethell, Edwin A. Bergin +2
We present results from a model of the chemical evolution of protoplanetary disks. In our models we directly calculate the changing propagation and penetration of a high energy rad…
Sensitive limits on the abundance of cold water vapor in the DM Tau protoplanetary disk
E. A. Bergin, M. R. Hogerheijde, C. Brinch +61
We performed a sensitive search for the ground-state emission lines of ortho- and para-water vapor in the DM Tau protoplanetary disk using the Herschel/HIFI instrument. No strong l…
