Complex Molecules in the L1157 Molecular Outflow
We report the detection of complex organic molecules in the young protostellar outflow L1157. We identify lines from HCOOCH3, CH3CN, HCOOH and C2H5OH at the position of the B1 shock in the blueshifted lobe, making it the first time that complex species have been detected towards a molecular outflow powered by a young low-mass protostar. The time scales associated with the warm outflow gas (< 2×...
متن کاملSubmillimeter CO emission from shock-heated gas in the L1157 outflow
We present the CO J=6–5, 4–3, and 3–2 spectra from the blueshifted gas of the outflow driven by the low-mass class 0 protostar in the L1157 dark cloud. Strong submillimeter CO emission lines with Tmb > 30 K have been detected at 63 (∼0.13 pc) south from the protostar. It is remarkable that the blue wings in the submillimeter lines are stronger by a factor of 3–4 than that of the CO J=1–0 emissi...
متن کاملA molecular outflow in the Circinus galaxy ?
From previous work on the Circinus galaxy we postulated that ≈ 50% of the molecular gas in this type 2 Seyfert nucleus is distributed in a sub-kiloparsec circumnuclear ring, probably associated with the ongoing star-burst. In addition to this, we postulated the possible presence of a molecular outflow along the galaxy's minor axis. In this work we use a modified version of the routine used prev...
متن کاملMolecular Devices. Chiral, Bichromophoric Silicones: Ordering Principles in Complex Molecules
There is a demand in modern technology for IT devices with high speeds of operation and high integration. Moore’s law [1] predicts a doubling of complexity for storage every two years and is one popular expression for the tendencies to increase the performance of devices concerning size and speed. One can ask if there is a natural limit for the speed of operation, what factors are limiting this...
متن کاملOutflow Driven Turbulence in Molecular Clouds
In this paper we explore the relationship between protostellar outflows and turbulence in molecular clouds. Using 3-D numerical simulations we focus on the hydrodynamics of multiple outflows interacting within a parsec scale volume. We explore the extent to which transient outflows injecting directed energy and momentum into a sub-volume of a molecular cloud can be converted into random turbule...
