Complex molecules in the Orion Kleinmann-Low nebula
BIO Web of Conferences, 2014 In the framework of the delivery to the early Earth of extraterrestrial molecules, we have studied complex molecular species toward the Orion Kleinmann-Low nebula. This nebula is rich in molecules as well as in nascent stars and planetary systems.

An Ionized Outflow in Orion-KL Source I?
The Astrophysical Journal, 2023 We present images at 6 and 14 GHz of Source I (SrcI) in the Kleinmann–Low Nebula in Orion. At higher frequencies, from 43 to 340 GHz, images of this source are dominated by thermal emission from dust in a 100 au diameter circumstellar disk, but at 6 and ...

Stable Coronal X-Ray Emission over 20 yr of XZ Tau
The Astronomical Journal, 2023 XZ Tau AB is a frequently observed binary young stellar object in the Taurus Molecular Cloud; XZ Tau B has been classified as an EXOr object. We present new Chandra/HETG-ACIS-S observations of XZ Tau AB, complemented with variability monitoring of the ...

Is stellar multiplicity universal? Tight stellar binaries in the Orion nebula Cluster [PDF]
, 2018 We present a survey for the tightest visual binaries among 0.3–2 M⊙ members of the Orion nebula Cluster (ONC). Among 42 targets, we discovered 13 new 0.025–0.15 arcsec companions. Accounting for the Branch bias, we find a companion star fraction (CSF) in

Deciphering the 3D Orion Nebula. II. A Low Ionization Region of Multiple Velocity Components Southwest of θ 1 Ori C Confounds Interpretation of Low Velocity Resolution Studies of Temperature, Density, and Abundance [PDF]
, 2020 We establish that there are two velocity systems along lines of sight that contribute to the emission-line spectrum of the brightest parts of the Orion Nebula.

Photograph of the Nebula in Orion [PDF]
Nature, 1880 DURING the night of September 30 I succeeded in photographing the bright part of the nebula in Orion in the vicinity of the trapezium. The photographs show the mottled appearance of this region distinctly. I intend shortly to publish a detailed description of the negatives. They were taken by the aid of a triple objective of eleven inches aperture made

Near-infrared Circular Polarization Images of NGC 6334-V [PDF]
, 2013 We present results from deep imaging linear and circular polarimetry of the massive star-forming region NGC 6334-V. These observations show high degrees of circular polarization (CP), as much as 22% in the Ks band, in the infrared nebula associated with ...
