We report new high resolution (0.6 − 1.7′′) images of GM Aur in the 12CO J = 2→1 line and the 1.3 and 2.7 mm continuum. The dust disk, located at the center of the CO disk, is resolved by the 0.6′′ beam of the interferometer. We derive a minimum radius of ∼ 200 AU, and a total mass (dust+gas) of about ∼ 0.025M . Our CO observations also resolve the Keplerian rotation of the gas disk. Since the ...

Using 12CO and 13CO liganded protein and 406 nm laser excitation, multiple stretching (upsilon(Fe-CO), upsilon(C-O)) and bending (delta(Fe-C-O)) modes have been identified in the resonance Raman spectra of monomeric and polymeric Glycera hemoglobins. While the monomer fraction Glycera dibranchiata hemoglobin has upsilon(Fe-CO) = 496 cm-1, two distinct upsilon(Fe-CO) modes are found at 498 cm-1 ...

Episodic accretion is a low-mass pre-main sequence phenomenon characterized by sudden outbursts of enhanced accretion. These objects are classified into two: protostars with elevated levels that lasts for decades or more, called FUors, and shorter repetitive bursts, EXors. HBC 494 FUor object embedded in the Orion Molecular Cloud. Earlier Atacama Large (sub-)Millimeter Array (ALMA) continuum ob...

We present millimeter molecular line observations towards the embedded infrared source IRAS 13036-7644, located in the globule DC 303.8-14.2. The CS(J=2–1) lines show asymmetrical profiles characteristic of a cloud undergoing gravitational collapse, i.e. double-peaked profiles with a brighter blue-shifted component. In contrast the HCO+(J=1–0) line shows towards the IRAS source a double-peaked ...

The distribution of 12CO(1–0) has been mapped over the spiral galaxy NGC 253 using the Swedish-ESO Submillimetre Telescope (SEST). Emission was found to extend 22.4 arcmin along themajor axis and to be concentrated towards the nucleus with an LSR systemic velocity of 235 km s−1. The CO intensity and velocity distribution suggests three subsystems: a dense, highly-rotating nuclear cloud, a disk ...
