Near-infrared spectroscopy of embedded protostars in the massive metal-poor star-forming region NGC 346
O. C. Jones, M. Reiter, R. Sanchez-Janssen +4
We present medium-resolution (R 4000) YJ, H \& K band spectroscopy of candidate young stellar objects (YSOs) in NGC~346, the most active star-formation region in the metal-p…
Unidentified emission features in the R Coronae Borealis star V854 Centauri
L. C. Oostrum, B. B. Ochsendorf, L. Kaper +1
During its 2012 decline the R Coronae Borealis star (RCB) V854 Cen was spectroscopically monitored with X-shooter on the ESO Very Large Telescope. The obscured optical and near-inf…
Massive pre-main sequence stars in M17
María Claudia Ramírez-Tannus, Lex Kaper, Alex de Koter +6
The formation process of massive stars is still poorly understood. Massive young stellar objects (mYSOs) are deeply embedded in their parental clouds, they are rare and thus typica…
XSHOOTER spectroscopy of the enigmatic planetary nebula Lin49 in the Small Magellanic Cloud
Masaaki Otsuka, F. Kemper, M. L. Leal-Ferreira +6
We performed a detailed spectroscopic analysis of the fullerene C60-containing planetary nebula (PN) Lin49 in the Small Magellanic Cloud using XSHOOTER at the ESO VLT and the Spitz…
Depletion of chlorine into HCl ice in a protostellar core
M. Kama, E. Caux, A. Lopez-Sepulcre +9
The freezeout of gas-phase species onto cold dust grains can drastically alter the chemistry and the heating-cooling balance of protostellar material. In contrast to well-known spe…
First firm spectral classification of an early-B pre-main-sequence star: B275 in M17
B. B. Ochsendorf, L. E. Ellerbroek, R. Chini +4
The optical to near-infrared (300 - 2500 nm) spectrum of the candidate massive Young Stellar Object (YSO) B275, embedded in the star forming region M17, has been observed with X-sh…
On the interplay between flaring and shadowing in disks around Herbig Ae/Be stars
B. Acke, M. Min, M. van den Ancker +4
Based on the SED, Herbig stars have been categorized into two observational groups, reflecting their overall disk structure: group I members have disks with a higher degree of flar…
