C2D Spitzer-IRS spectra of disks around T Tauri stars. IV. Crystalline silicates
J. Olofsson, J. -C. Augereau, E. F. van Dishoeck +13
Dust grains in the planet forming regions around young stars are expected to be heavily processed due to coagulation, fragmentation and crystallization. This paper focuses on the c…
An X-ray photometry system I: Chandra ACIS
H. -J. Grimm, J. McDowell, G. Fabbiano +1
We present a system of X-ray photometry for the Chandra satellite. X-ray photometry can be a powerful tool to obtain flux estimates, hardness ratios, and colors unbiased by assumpt…
Probing dust grain evolution in IM Lupi's circumstellar disc. Multi-wavelength observations and modelling of the dust disc
C. Pinte, D. L. Padgett, F. Menard +19
We present a panchromatic study, involving a multiple technique approach, of the circumstellar disc surrounding the T Tauri star IM Lupi (Sz 82). We have undertaken a comprehensive…
The c2d Spitzer spectroscopy survey of ices around low-mass young stellar objects, III: CH4
Karin I. Oberg, A. C. Adwin Boogert, Klaus M. Pontoppidan +4
CH4 is proposed to be the starting point of a rich organic chemistry. Solid CH4 abundances have previously been determined mostly toward high mass star forming regions. Spitzer/IRS…
The c2d Spitzer Spectroscopic Survey of Ices Around Low-Mass Young Stellar Objects: I. H2O and the 5-8 um Bands
A. Boogert, K. Pontoppidan, C. Knez +23
With the goal to study the physical and chemical evolution of ices in solar-mass systems, a spectral survey is conducted of a sample of 41 low luminosity YSOs using 3-38 um Spitzer…
Cold Disks: Spitzer Spectroscopy of Disks around Young Stars with Large Gaps
J. M. Brown, G. A. Blake, C. P. Dullemond +10
We have identified four circumstellar disks with a deficit of dust emission from their inner 15-50 AU. All four stars have F-G spectral type, and were uncovered as part of the Spit…
