High Resolution Λ=1mm Carma Observations of Large Molecules in Orion-kl

چکیده

We present high resolution, Combined Array for Research in Millimeter-Wave Astronomy (CARMA), λ=1mm observations of several molecular species toward Orion-KL. These are the highest spatial and spectral resolution 1mm observations of these molecules to date. Our observations show that ethyl cyanide [C2H5CN] and vinyl cyanide [C2H3CN] originate from multiple cores near the Orion hot core and IRc7. Additionally we show that dimethyl ether [(CH3)2O] and methyl formate [HCOOCH3] originate from IRc5 and IRc6 and that acetone [(CH3)2CO] originates only from areas where both N-bearing and O-bearing species are present. Subject headings: astrochemistry—ISM:individual(Orion-KL)—ISM:molecules— radio lines:ISM

SEARCH FOR Λ-DOUBLING TRANSITIONS OF SiH IN ORION KL

A recent submillimeter line survey of Orion KL claimed detection of SiH. This paper reports on GBT observations of the 5.7 GHz Λ-doubling transitions of SiH in Orion. Many recombination lines, including C164δ, are seen, but SiH is not detected. The nondetection corresponds to an upper limit of 1.5×1015 cm−2 (4σ) for the beam-averaged column density of SiH. This suggests that the fractional abun...

Tracing the Bipolar Outflow from Orion Source I

Using CARMA, we imaged the 87 GHz SiO v=0 J=2-1 line toward Orion-KL with 0.45 angular resolution. The maps indicate that radio source I drives a bipolar outflow into the surrounding molecular cloud along a NE–SW axis, in agreement with the model of Greenhill et al. (2004). The extended high velocity outflow from Orion-KL appears to be a continuation of this compact outflow. High velocity gas e...

We present observations of the closest region of high mass star formation, Orion BN/KL, performed at both low resolution mode (grating mode) and high resolution (Fabry-Pérot mode) with the Long Wavelength Spectrometer (LWS) on board the Infrared Space Observatory (ISO). We detected the CO rotational transitions from J up = 15 to J up = 49. A LVG analysis of the line fluxes allows to distinguish...

Herschel observations of EXtra-Ordinary Sources: ANALYSIS OF THE HIFI 1.2 THz WIDE SPECTRAL SURVEY TOWARD ORION KL II. CHEMICAL IMPLICATIONS1

We present chemical implications arising from spectral models fit to the Herschel/HIFI spectral survey toward the Orion Kleinmann-Low nebula (Orion KL). We focus our discussion on the 8 complex organics detected within the HIFI survey utilizing a novel technique to identify those molecules emitting in the hottest gas. In particular, we find the complex nitrogen bearing species CH3CN, C2H3CN, C2...
