A mid-infrared study of HII regions in the Magellanic Clouds: N88A and N160A
N. L. Martin-Hernandez, E. Peeters, A. G. G. M. Tielens
To show the importance of high-spatial resolution observations of HII regions when compared with observations obtained with larger apertures such as ISO, we present mid-infrared sp…
Spatially resolved near-infrared spectroscopy of the massive star-forming region IRAS 19410+2336
N. L. Martin-Hernandez, A. Bik, E. Puga +2
IRAS19410+2336 is a young massive star forming region with an intense outflow activity. We present here spatially resolved NIR spectroscopy which allows us to verify whether the H2…
Probing the Early Evolution of Young High-Mass Stars
E. Puga, A. Bik, L. B. M. F. Waters +22
Near-infrared imaging surveys of high-mass star-forming regions reveal an amazingly complex interplay between star formation and the environment (Churchwell et al. 2006; Alvarez et…
M1-78: a nitrogen-rich Galactic compact HII region beyond the Perseus arm
N. L. Martin-Hernandez, C. Esteban, A. Mesa-Delgado +2
There is considerable controversy surrounding the nature of M1-78, a compact nebula located beyond the Perseus arm. It was first classified as a planetary nebula and is nowadays ge…
High spatial resolution mid-infrared spectroscopy of the starburst galaxies NGC 3256, IIZw40 and Henize 2-10
N. L. Martin-Hernandez, D. Schaerer, E. Peeters +2
In order to show the importance of high spatial resolution observations of extra-galactic sources when compared to observations obtained with larger apertures such as ISO, we prese…
High excitation ISM and gas
E. Peeters, N. L. Martin-Hernandez, N. J. Rodriguez-Fernandez +1
An overview is given of ISO results on regions of high excitation ISM and gas, i.e. HII regions, the Galactic Centre and Supernovae Remnants. IR emission due to fine-structure line…
High spatial resolution mid-infrared spectroscopy of NGC 5253: The stellar content of the embedded super-star cluster
N. L. Martin-Hernandez, D. Schaerer, M. Saugave
We present the N-band (8-13 micron) spectrum of the hidden compact radio super-star cluster in NGC 5253, C2, obtained with TIMMI2 on the ESO 3.6m telescope. The spectrum is charact…
A VLT spectroscopic study of the ultracompact HII region G29.96-0.02
N. L. Martin-Hernandez, A. Bik, L. Kaper +2
A high quality, medium-resolution K-band spectrum has been obtained of the ultracompact HII region G29.96-0.02 with the Very Large Telescope (VLT). The slit was positioned along th…
The stellar content, metallicity and ionization structure of HII regions
N. L. Martin-Hernandez, R. Vermeij, A. G. G. M. Tielens +2
Observations of infrared fine-structure lines provide direct information on the metallicity and ionization structure of HII regions and indirectly on the hardness of the radiation…
A photoionization model of the compact HII region G29.96-0.02
C. Morisset, D. Schaerer, N. -L. Martin-Hernandez +5
We present a detailed photoionization model of G29.96-0.02 (hereafter G29.96), one of the brightest Galactic Ultra Compact HII (UCHII) regions in the Galaxy. This source has been o…
ISO spectroscopy of compact HII regions in the Galaxy. II Ionization and elemental abundances
N. L. Martin-Hernandez, E. Peeters, C. Morisset +9
Based on the ISO spectral catalogue of compact HII regions by Peeters et al. (2001), we present a first analysis of the hydrogen recombination and atomic fine-structure lines origi…
