The Molecular Envelope around the Red Supergiant Vy Cma
We present millimeter interferometric observations of the molecular envelope around the red supergiant VY CMa with the SubMillimeter Array (SMA) . The high angular resolution (< 2) allows us to derive the structure of the envelope as observed in the 1.3 mm continuum, CO(2-1), CO(2-1) and SO(65-54) lines emission. The circumstellar envelope is resolved into three components: a dense, compact and...
متن کاملMissing baryons in shells around galaxy clusters
Aims. The cluster baryon fraction is estimated from the CMB-scattering leptonic component of the intracluster medium (ICM); however, the observed cluster baryon fraction is less than the cosmic one. Understanding the origin of this discrepancy is necessary for correctly describing the structure of the ICM. Methods. We estimate the baryonic mass in the outskirts of galaxy clusters which is diffi...
متن کاملImaging of detached shells around the carbon stars
We present the first optical images of scattered light from large, detached gas/dust shells around two carbon stars, R Scl and U Ant, obtained in narrow band filters centred on the resonance lines of neutral K and Na, and in a Strömgren b filter (only U Ant). They confirm results obtained in CO radio line observations, but also reveal new and interesting structures. Towards R Scl the scattering...
متن کاملStructure and dynamics of solvent shells around photoexcited metal complexes.
Understanding the geometry, energetics and dynamics of solvated transition metal (TM) compounds is decisive in characterizing and optimizing their function. Here, we demonstrate that it is possible to quantify the structural dynamics of solvated [Ru(II)(bpy)3], an important TM-complex for solar-energy harvesting research, by using state-of-the art force fields together with molecular simulation...
متن کاملHydrodynamic Thermonuclear Runaways in Superbursts
We calculate the thermal and dynamical evolution of the surface layers of an accreting neutron star during the rise of a superburst. For the first few hours following unstable C ignition, the nuclear energy release is transported by convection. However, as the base temperature rises, the heating time becomes shorter than the eddy turnover time and convection becomes inefficient. This results in...
