Rotational Line Emission from Water in Protoplanetary Disks
R. Meijerink, D. R. Poelman, M. Spaans +2
Circumstellar disks provide the material reservoir for the growth of young stars and for planet formation. We combine a high-level radiative transfer program with a thermal-chemica…
The Molecular Hydrogen Explorer H2EX
F. Boulanger, J. P. Maillard, P. Appleton +12
The Molecular Hydrogen Explorer, H2EX, was proposed in response to the ESA 2015 - 2025 Cosmic Vision Call as a medium class space mission with NASA and CSA participations. The miss…
The characteristics of the IR emission features in the spectra of Herbig Ae stars: Evidence for chemical evolution
C. Boersma, J. Bouwman, F. Lahuis +4
Herbig Ae/Be stars are a class of young pre-main sequence stellar objects of intermediate mass and are known to have varying amounts of natal cloud material still present in their…
Chemical Rates on Small Grains and PAHs: C^+ Recombination and H_2 Formation
Mark G. Wolfire, A. G. G. M. Tielens, David Hollenbach +1
We use observations of the CI, CII, HI, and H_2 column densities along lines of sight in the Galactic plane to determine the formation rate of H_2 on grains and to determine chemic…
Co-Accretion of Chondrules and Dust in the Solar Nebula
C. W. Ormel, J. N. Cuzzi, A. G. G. M. Tielens
We present a mechanism for chondrules to stick together by means of compaction of a porous dust rim they sweep up as they move through the dusty nebula gas. It is shown that dust a…
Binarity as a key factor in protoplanetary disk evolution: Spitzer disk census of the eta Chamaeleontis cluster
J. Bouwman, W. A. Lawson, C. Dominik +4
The formation of planets is directly linked to the evolution of the circumstellar (CS) disk from which they are born. The dissipation timescales of CS disks are, therefore, of dire…
