Properties of protostars in the Elephant Trunk globule IC 1396A
William T. Reach, Dohy Faied, Jeonghee Rho +7
Extremely red objects, identified in the early Spitzer Space Telescope observations of the bright-rimmed globule IC 1396A and photometrically classified as Class I protostars Class…
Can We Trust the Dust? Evidence of Dust Segregation in Molecular Clouds
Paolo Padoan, Laurent Cambresy, Mika Juvela +3
Maps of estimated dust column density in molecular clouds are usually assumed to reliably trace the total gas column density structure. In this work we present results showing a cl…
Properties of dust and detection of Halpha emission in LDN 1780
C. del Burgo, L. Cambresy
We present ISOPHOT observations between 60 and 200 microns and a near-infrared extinction map of LDN 1780. We have used the ISOPHOT data together with the 25, 60 and 100 microns IR…
Luminous AGB stars in nearby galaxies. A study using Virtual Observatory tools
P. Tsalmantza, E. Kontizas, L. Cambresy +3
Aims. This study focuses on very luminous Mbol<-6.0 mag AGB stars with J-Ks>1.5 mag and H-Ks>0.4 mag in the LMC, SMC, M31, and M33 from 2MASS data. Methods.The data were taken from…
Surface density of the young cluster IC 348 in the Perseus molecular cloud
L. Cambresy, V. Petropoulou, M. Kontizas +1
The IC 348 young star cluster contains more than 300 confirmed members. It is embedded in the Perseus molecular cloud, making any clustering analysis subject to an extinction bias.…
Large-scale variations of the dust optical properties in the Galaxy
L. Cambresy, T. H. Jarrett, C. A. Beichman
We present an analysis of the dust optical properties at large scale, for the whole galactic anticenter hemisphere. We used the 2MASS Extended Source Catalog to obtain the total re…
