A 42.3-43.6 GHz SPECTRAL SURVEY OF ORION BN/KL: FIRST DETECTION OF THEv= 0J= 1-0 LINE FROM THE ISOTOPOLOGUES29SiO AND30SiO
2009
Astrophysical Journal
We have surveyed molecular line emission from Orion BN/KL from 42.3 to 43.6 GHz with the Green Bank Telescope. Sixty-seven lines were identified and ascribed to 13 different molecular species. The spectrum at 7 mm is dominated by SiO, SO2, CH3OCH3, and C2H5CN. Five transitions have been detected from the SiO isotopologues 28SiO, 29SiO, and 30SiO. We report here for the first time the spectra of the 29SiO and 30SiO v=0 J=1-0 emission in Orion BN/KL, and we show that they have double-peaked
