Atomic silicon towards the Orion-KL nebula
We have used the Long Wavelength Spectrometer (LWS) on board ISO to observe the fine structure lines of atomic silicon at 68.5 and 129.7 microns towards the Orion KleinmannLow nebula. Our data show evidence for the detection of the J=2-1 transition at 68.5μm with a signal-to-noise ratio of 5. We consider the formation of the observed emission line and conclude that it is likely to form in the C...
متن کاملSEARCH 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...
متن کاملThe Distribution of Deuterated Formaldehyde within Orion-kl
We report the first high angular resolution imaging (3.4× 3.0) of deuterated formaldehyde (HDCO) toward Orion–KL, carried out with the Submillimeter Array (SMA). We find that the spatial distribution of the formaldehyde emission systematically differs from that of methanol: while methanol is found towards the inner part of the region, HDCO is found in colder gas that wraps around the methanol e...
متن کاملDetection of Interstellar Acetone toward the Orion-kl Hot Core
We present the first detection of interstellar acetone [(CH3)2CO] toward the high mass star forming region Orion-KL and the first detection of vibrationally excited (CH3)2CO in the ISM. Using the BIMA Array, 28 emission features that can be assigned to 54 acetone transitions were detected. Furthermore, 37 of these transitions have not been previously observed in the ISM. The observations also s...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
