The Integral Field View of the Orion Nebula [PDF]
Advances in Astronomy, 2014 This paper reviews the major advances achieved in the Orion Nebula through the use of integral field spectroscopy (IFS). Since the early work of Vasconcelos and collaborators in 2005, this technique has facilitated the investigation of global properties ...

Which Stars are Ionizing the Orion Nebula ? [PDF]
The Astrophysical Journal, 2017 The common assumption that Theta-1-Ori C is the dominant ionizing source for the Orion Nebula is critically examined. This assumption underlies much of the existing analysis of the nebula.

The distance to the Orion Nebula [PDF]
Astronomy & Astrophysics, 2007 We have used the Very Long Baseline Array to measure the trigonometric parallax of several member stars of the Orion Nebula Cluster showing non-thermal radio emission. We have determined the distance to the cluster to be 414 +/- 7 pc.

On the Structure of the Orion A Cloud and the Formation of the Orion Nebula Cluster [PDF]
The Astrophysical Journal, 2006 We suggest that the Orion A cloud is gravitationally collapsing on large scales, and is producing the Orion Nebula Cluster due to the focusing effects of gravity acting within a finite cloud geometry.

Layers in the Central Orion nebula [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 The existence of multiple layers in the inner Orion Nebula has been revealed using data from an Atlas of spectra at 2" and 12 km/s resolution. These data were sometimes grouped over Samples of 10"x10"to produce high Signal to Noise spectra and sometimes ...

Spectrophotometry of the Orion Nebula [PDF]
Publications of the Astronomical Society of the Pacific, 1973 Observations of line and continuum strengths were made in six regions in the Orion nebula. From the observations, electron temperatures, electron densities, and chemical abundances are derived. A model for the Orion nebula is computed that agrees with the optical and radio observations of the nebula.

The NII spectrum of the Orion Nebula [PDF]
Monthly Notices of the Royal Astronomical Society, 2005 The predicted emission spectrum of NII is compared with observations of permitted lines in the Orion nebula. Conventional nebular models show that the intensities of the more intense lines can be explained by fluorescence of starlight absorption with a N

Multiple star systems in the Orion nebula [PDF]
Astronomy & Astrophysics, 2018 This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium cluster with the recently comissioned GRAVITY instrument. We observed a total of 16 stars of mainly OB spectral type.
