Rotation in the Orion Nebula Cluster [PDF]
The Astronomical Journal, 1999 Eighteen fields in the Orion Nebula Cluster (ONC) have been monitored for one or more observing seasons from 1990-99 with a 0.6-m telescope at Wesleyan University. Photometric data were obtained in Cousins I on 25-40 nights per season.

A MUSE map of the central Orion Nebula (M 42) [PDF]
, 2015 We present a new integral-field spectroscopic dataset of the central part of the Orion Nebula (M 42), observed with the MUSE instrument at the ESO VLT. We reduced the data with the public MUSE pipeline.

Turbulence in the Ionized Gas of the Orion Nebula [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 In order to study the nature, origin, and impact of turbulent velocity fluctuations in the ionized gas of the Orion Nebula, we apply a variety of statistical techniques to observed velocity cubes.

PDRs4All. II. JWST's NIR and MIR imaging view of the Orion Nebula [PDF]
Astronomy & Astrophysics, 2023 The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypical highly irradiated dense photo-dissociation region (PDR). We investigate

Photoionized Herbig-Haro objects in the Orion Nebula through deep high-spectral resolution spectroscopy III: HH 514 [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We analyze the physical conditions and chemical composition of the photoionized Herbig-Haro object HH 514, which emerges from the proplyd 170-337 in the core of the Orion Nebula.

Demographics of the M-star Multiple Population in the Orion Nebula Cluster [PDF]
Astrophysical Journal, 2022 We present updated results constraining multiplicity demographics for the stellar population of the Orion Nebula Cluster (ONC, a high-mass, high-density star-forming region), across primary masses 0.08–0.7 M ⊙.

Primordial Helium-3 Redux: The Helium Isotope Ratio of the Orion Nebula [PDF]
Astrophysical Journal, 2022 We report the first direct measurement of the helium isotope ratio, 3He/4He, outside of the Local Interstellar Cloud, as part of science-verification observations with the upgraded CRyogenic InfraRed Echelle Spectrograph.

The 3D Kinematics of the Orion Nebula Cluster: NIRSPEC-AO Radial Velocities of the Core Population [PDF]
Astrophysical Journal, 2021 The kinematics and dynamics of stellar and substellar populations within young, still-forming clusters provide valuable information for constraining theories of formation mechanisms.

Binary Formation in the Orion Nebula Cluster: Exploring the Substellar Limit [PDF]
Astrophysical Journal, 2021 We present results constraining the multiplicity of the very low mass stars and substellar objects in the Orion Nebula Cluster (ONC). Our sample covers primary masses 0.012–0.1 M ⊙ using archival Hubble Space Telescope data obtained with the Advanced ...
