Circumstellar disks around Herbig Be stars
T. Alonso-Albi, A. Fuente, R. Bachiller +5
We completed a search for circumstellar disks around Herbig Be stars using the NRAO Very Large Array (VLA) and the IRAM Plateau de Bure (PdB) interferometers. We present our new VL…
What can we learn about protoplanetary disks from analysis of mid-infrared carbonaceous dust emission?
O. Berne, C. Joblin, A. Fuente +1
In this Paper we analyze the mid-infrared (mid-IR) emission of very small dust particles in a sample of 12 protoplanetary disks to see how they are connected to interstellar dust p…
Carriers of the mid-IR emission bands in PNe reanalysed. Evidence of a link between circumstellar and interstellar aromatic dust
C. Joblin, R. Szczerba, O. Berne +1
It has been shown that the diversity of the aromatic emission features can be rationalized into different classes of objects, in which differences between circumstellar and interst…
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…
Extended Red Emission and the evolution of carbonaceaous nanograins in NGC 7023
O. Berne, C. Joblin, M. Rapacioli +3
Extended Red Emission (ERE) was recently attributed to the photo-luminescence of either doubly ionized Polycyclic Aromatic Hydrocarbons (PAH), or charged PAH dimers. We anal…
Blind Signal Separation Methods for the Identification of Interstellar Carbonaceous Nanoparticles
Olivier Berne, Yannick Deville, Christine Joblin
The use of Blind Signal Separation methods (ICA and other approaches) for the analysis of astrophysical data remains quite unexplored. In this paper, we present a new approach for…
