Spitzer's mid-infrared view on an outer Galaxy Infrared Dark Cloud candidate toward NGC 7538
W. F. Frieswijk, M. Spaans, R. F. Shipman +3
Infrared Dark Clouds (IRDCs) represent the earliest observed stages of clustered star formation, characterized by large column densities of cold and dense molecular material observ…
Star Formation Near Photodissociation Regions: Detection of a Peculiar Protostar Near Ced 201
Javier R. Goicoechea, Olivier Berne, Maryvonne Gerin +2
We present the detection and characterization of a peculiar low-mass protostar (IRAS 22129+7000) located ~0.4 pc from Ced 201 Photodissociation Region (PDR) and ~0.2 pc from the HH…
The Horsehead mane: Towards an observational benchmark for chemical models
Jérôme Pety, Javier R. Goicoechea, Maryvonne Gerin +5
After a discussion about the need for observational benchmark for chemical models, we explain 1) why the Horsehead western edge is well suited to serve as reference for models and…
Physical Characteristics of a Dark Cloud in an Early Stage of Star Formation toward NGC 7538: an Outer Galaxy Infrared Dark Cloud?
Wilfred W. F. Frieswijk, Marco Spaans, Russell F. Shipman +2
In the inner parts of the Galaxy the Infrared Dark Clouds (IRDCs) are presently believed to be the progenitors of massive stars and star clusters. Many of them are predominantly de…
Low sulfur depletion in the Horsehead PDR
J. R. Goicoechea, J. Pety, M. Gerin +4
We present 3.65''x3.34'' angular-resolution IRAM PdBI observations of the CS J=2-1 line toward the Horsehead Photodissociation Region (PDR), complemented with IRAM-30m single-dish…
Detection of CO+ in the nucleus of M82
A. Fuente, S. Garcia-Burillo, M. Gerin +5
We present the detection of the reactive ion CO+ towards the prototypical starburst galaxy M82. This is the first secure detection of this short-lived ion in an external galaxy. Va…
