Accretion in Brown Dwarfs: an Infrared View
A. Natta, L. Testi, J. Muzerolle +3
This paper presents a study of the accretion properties of 19 very low mass objects (Mstar .01-0.1 Msun) in the regions Chamaeleon I and rho-Oph For 8 objects we obtained high reso…
Optical spectra of selected Chamaeleon I young stellar objects
C. Saffe, M. Gomez, S. Randich +4
We present optical spectra of eight candidate brown dwarfs and a previously known T Tauri star (Sz 33) of the Chamaeleon I dark cloud. We derived spectral types based on the streng…
The Science Case for PILOT I: Summary and Overview
J. S. Lawrence, M. C. B. Ashley, J. Bailey +40
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5 m optical/infrared telescope to be located at Dome C on the Antarctic plateau. Conditions at D…
ISOCAM observations of the rho Ophiuchi cloud: Luminosity and mass functions of the pre-main sequence embedded cluster
S. Bontemps, P. Andre, A. A. Kaas +19
We present the results of the first extensive mid-infrared (IR) imaging survey of the rho Ophiuchi embedded cluster, performed with the ISOCAM camera on board the ISO satellite. Th…
The DENIS Point Source Catalogue towards the Magellanic Clouds
M-R. Cioni, C. Loup, H. J. Habing +25
We have compiled the near infrared Point Source Catalogue (PSC) towards the Magellanic Clouds (MCs) extracted from the data obtained with the Deep Near Infrared Survey of the South…
Mid Infrared Photometry of Mass-Losing AGB Stars
M. Busso, R. Guandalini, P. Persi +2
We present ground-based mid-infrared imaging for 27 M-, S- and C-type Asymptotic Giant Branch (AGB) stars. The data are compared with those of the database available thanks to the…
ISOCAM-CVF spectroscopy of the circumstellar environment of young stellar objects
R. D. Alexander, M. M. Casali, P. M. Andre +2
We present the results of a mid-infrared imaging spectroscopy survey of Young Stellar Objects (YSOs) and their surrounding environment in four low-mass star formation regions: RCrA…
The INTEGRAL source IGR J16328-4726: a High Mass X-ray Binary from the Beppo SAX era
M. Fiocchi, A. Bazzano, A. J. Bird +5
We report on temporal and spectral analysis of the INTEGRAL fast transient candidate IGR J16328-4726 observed with Beppo SAX in 1998 and more recently with INTEGRAL. The MECS X-ray…
The earliest phases of high-mass star formation, as seen in NGC 6334 by \emph{Herschel}
J. Tigé, F. Motte, D. Russeil +33
To constrain models of high-mass star formation, the Herschel/HOBYS KP aims at discovering massive dense cores (MDCs) able to host the high-mass analogs of low-mass prestellar core…
ISOCAM observations of the L1551 star formation region
M. GÃ¥lfalk, G. Olofsson, A. A. Kaas +17
The results of a deep mid-IR ISOCAM survey of the L1551 dark molecular cloud are presented. The aim of this survey is a search for new YSO (Young Stellar Object) candidates, using…
Herschel observations of embedded protostellar clusters in the Rosette Molecular Cloud
M. Hennemann, F. Motte, S. Bontemps +39
The Herschel OB young stellar objects survey (HOBYS) has observed the Rosette molecular cloud, providing an unprecedented view of its star formation activity. These new far-infrare…
Mid-infrared imaging of AGB star envelopes. II. Modelling of observed sources
M. Marengo, G. Canil, G. Silvestro +3
Radiative transfer modelling of AGB circumstellar envelopes is applied to a sample of AGB stars previously observed with the mid-IR imaging camera TIRCAM (Busso et al. 1996: Paper…
Infrared Photometry and Evolution of Mass-Losing AGB Stars I. Carbon Stars Revisited
R. Guandalini, M. Busso, S. Ciprini +2
As part of a reanalysis of galactic Asymptotic Giant Branch (AGB) stars at infrared (IR) wavelengths, we discuss a sample (357) of carbon stars for which mass loss rates, near-IR p…
Small-scale structure in the Rosette molecular cloud revealed by Herschel
J. Di Francesco, S. Sadavoy, F. Motte +40
We present a preliminary analysis of the small-scale structure found in new 70-520 micron continuum maps of the Rosette molecular cloud (RMC), obtained with the SPIRE and PACS inst…
The young stellar population in the Serpens Cloud Core: An ISOCAM survey
A. A. Kaas, G. Olofsson, S. Bontemps +18
We present results from an ISOCAM survey in the two broad band filters LW2 (5-8.5 mu) and LW3 (12-18 mu) of a 0.13 square degree coverage of the Serpens Main Cloud Core. A total of…
The Herschel view of star formation in the Rosette molecular cloud under the influence of NGC 2244
N. Schneider, F. Motte, S. Bontemps +43
The Rosette molecular cloud is promoted as the archetype of a triggered star-formation site. This is mainly due to its morphology, because the central OB cluster NGC 2244 has blown…
The XMM Newton and INTEGRAL observations of the supergiant fast X-ray transient IGR J16328-4726
M. Fiocchi, A. Bazzano, L. Natalucci +6
The accretion mechanism producing the short flares observed from the Supergiant Fast X-ray Transients (SFXT) is still highly debated and forms a major part in our attempts to place…
