The distance to the Orion Nebula cluster [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
Abstract The distance to the Orion Nebula cluster (ONC) is estimated using the rotational properties of its low-mass pre-main-sequence (PMS) stars. Rotation periods, projected equatorial velocities and distance-dependent radius estimates are used to form an observational sin i distribution (where i is the axial inclination), which is ...

Candidates for Substellar Members of the Orion Nebula Cluster from JWST/NIRCam

The Astronomical Journal
In 2022, the James Webb Space Telescope (JWST) obtained 1–5 μ m images of the center of the Orion Nebula Cluster (ONC). I have analyzed these data in an attempt to search for substellar members of the cluster. Using a pair of color–color diagrams, I have

The Robust Detection and Spatial Distribution of Acetaldehyde in Orion KL: Atacama Large Millimeter/submillimeter Array Observations and Chemical Modeling

The Astrophysical Journal
Despite the organic molecule inventory detected in the Orion Kleinmann–Low Nebula (Orion KL), acetaldehyde (CH _3 CHO)—one of the most ubiquitous interstellar aldehydes—has not been firmly identified with millimeter-wave interferometry.

Discovery of Radio Recombination Lines from Proplyds in the Orion Nebula Cluster

The Astrophysical Journal
We present new Atacama Large Millimeter/submillimeter Array observations that, for the first time, detect hydrogen and helium radio recombination lines from a protoplanetary disk.

Tests of Disk-locking in T Tauri Stars of the Orion Nebula Cluster

The Astrophysical Journal
We look for specific correlations predicted by magnetospheric accretion models for young stars that assume disk-locking using stellar and accretion parameters derived from low-resolution HST-STIS spectra of 33 T Tauri stars in the Orion Nebula Cluster ...

Chemistry in Externally FUV-irradiated Disks in the Outskirts of the Orion Nebula Cluster

The Astrophysical Journal
Most stars are born in stellar clusters, and their protoplanetary disks, which are the birthplaces of planets, can, therefore, be affected by the radiation of nearby massive stars.

The Nature of X-Rays from Young Stellar Objects in the Orion Nebula Cluster—A Chandra HETGS Legacy Project

The Astrophysical Journal
The Orion Nebula Cluster (ONC) is the closest site of very young (∼1 Myr) massive star formation The ONC hosts more than 1600 young and X-ray bright stars with masses ranging from ∼0.1–35 M _⊙ .
