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…
Characterisation of the Planetary Nebula Tc 1 Based on VLT X-Shooter Observations
Isabel Aleman, Marcelo L. Leal-Ferreira, Jan Cami +11
We present a detailed analysis of deep VLT/X-Shooter observations of the planetary nebula Tc 1. We calculate gas temperature, density, extinction, and abundances for several specie…
The star-forming complex LMC-N79 as a future rival to 30 Doradus
Bram B. Ochsendorf, Hans Zinnecker, Omnarayani Nayak +5
Within the early Universe, `extreme' star formation may have been the norm rather than the exception. Super Star Clusters (SSCs; 10 M) are thought t…
[CII] emission from L1630 in the Orion B molecular cloud
C. H. M. Pabst, J. R. Goicoechea, D. Teyssier +11
Observations towards L1630 in the Orion B molecular cloud, comprising the iconic Horsehead Nebula, allow us to study the interplay between stellar radiation and a molecular cloud u…
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…
What sets the massive star formation rates and efficiencies of giant molecular clouds?
Bram B. Ochsendorf, Margaret Meixner, Julia Roman-Duval +2
Galactic star formation scaling relations show increased scatter from kpc to sub-kpc scales. Investigating this scatter may hold important clues to how the star formation process e…
The location, clustering, and propagation of massive star formation in giant molecular clouds
B. B. Ochsendorf, M. Meixner, J. Chastenet +2
Massive stars are key players in the evolution of galaxies, yet their formation pathway remains unclear. In this work, we use data from several galaxy-wide surveys to build an unbi…
Kompaneets Model Fitting of the Orion-Eridanus Superbubble II: Thinking Outside of Barnard's Loop
Andy Pon, Bram B. Ochsendorf, João Alves +3
The Orion star-forming region is the nearest active high-mass star-forming region and has created a large superbubble, the Orion-Eridanus superbubble. Recent work by Ochsendorf et…
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…
Nested shells reveal the rejuvenation of the Orion-Eridanus superbubble
B. B. Ochsendorf, A. G. A. Brown, J. Bally +1
The Orion-Eridanus superbubble is the prototypical superbubble due to its proximity and evolutionary state. Here, we provide a synthesis of recent observational data from WISE and…
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…
Kompaneets Model Fitting of the Orion-Eridanus Superbubble
Andy Pon, Doug Johnstone, John Bally +1
Winds and supernovae from OB associations create large cavities in the interstellar medium referred to as superbubbles. The Orion molecular clouds are the nearest high mass star-fo…
VLT/X-shooter survey of near-infrared diffuse interstellar bands
N. L. J. Cox, J. Cami, L. Kaper +5
This paper presents a spectral survey of diffuse interstellar bands (DIBs) in the NIR range, from 0.9 to 2.5 micron. The observations were designed to detect new DIBs, confirm prev…
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…
