Lack of PAH emission toward low-mass embedded young stellar objects
V. C. Geers, E. F. van Dishoeck, K. M. Pontoppidan +4
PAHs have been detected toward molecular clouds and some young stars with disks, but have not yet been associated with embedded young stars. We present a sensitive mid-IR spectrosc…
Survey of ortho-H2D+(1_{1,0}-1_{1,1}) in dense cloud cores
Paola Caselli, Charlotte Vastel, Cecilia Ceccarelli +3
We present a survey of the ortho-H2D+(1_{1,0}-1_{1,1}) line toward a sample of 10 starless cores and 6 protostellar cores, carried out at the Caltech Submillimeter Observatory. The…
Identifying the Low Luminosity Population of Embedded Protostars in the c2d Observations of Clouds and Cores
Michael M. Dunham, Antonio Crapsi, Neal J. Evans +4
We present a search for all embedded protostars with internal luminosities < 1 solar luminosity in the sample of nearby, low-mass star-forming regions surveyed by the Spitzer Space…
SMA observations of young disks: separating envelope, disk, and stellar masses in class I YSOs
Dave Lommen, Jes Jorgensen, Ewine van Dishoeck +1
(abbreviated) We aim to determine the masses of the envelopes, disks, and central stars of young stellar objects (YSOs) in the Class I stage. We observed the embedded Class I objec…
Characterizing the nature of embedded young stellar objects through silicate, ice and millimeter observations
A. Crapsi, E. F. van Dishoeck, M. R. Hogerheijde +2
(Abridged) Classification schemes for YSOs are based on evaluating the degree of dissipation of the surrounding envelope, whose main effects are the extinction of the optical radia…
A deeply embedded young protoplanetary disk around L1489 IRS observed by the submillimeter array
C. Brinch, A. Crapsi, J. K. Jorgensen +2
Circumstellar disks are expected to form early in the process that leads to the formation of a young star, during the collapse of the dense molecular cloud core. It is currently no…
