Does IRAS 16293-2422 contain a hot core? New interferometric results
F. L. Schoeier, J. K. Jorgensen, E. F. van Dishoeck +1
High angular resolution H2CO line observations have been carried out for the low mass proto-binary star IRAS 16293-2422 using the OVRO millimeter array. Simultaneous continuum obse…
Interferometric Observations of Formaldehyde in the Protoplanetary Disk around LkCa15
Yuri Aikawa, Munetake Momose, Wing-Fai Thi +4
Emission from the line of HCO has been detected and marginally resolved toward LkCa15 by the Nobeyama Millimeter Array. The column density of HCO is higher…
Millimeter-wave Searches for Cold Dust and Molecular Gas around T Tauri Stars in MBM 12
Michiel R. Hogerheijde, Ray Jayawardhana, Doug Johnstone +2
We report results of a sensitive search for cold dust and molecular gas in the disks around 8 T Tauri stars in the high-latitude cloud MBM 12. Interferometric observations of 3 mm…
Looking for Pure Rotational H_2 Emission from Protoplanetary Disks
M. J. Richter, D. T. Jaffe, Geoffrey A. Blake +1
We report on a limited search for pure-rotational molecular hydrogen emission associated with young, pre-main-sequence stars. We looked for H_2 v=0 J = 3->1 and J = 4->2 emission i…
The Environment and Nature of the Class I Protostar Elias 29: Molecular Gas Observations and the Location of Ices
A. C. A. Boogert, M. R. Hogerheijde, C. Ceccarelli +5
A (sub-)millimeter line and continuum study of the class I protostar Elias 29 in the Rho Ophiuchi molecular cloud is presented, whose goals are to understand the nature of this sou…
