... Accurate identification of physical binary star systems has become of increasing interest in recent years. ... Identification of physical binary star systems, with an estimated reliability of such identifications based on the theory of probability, is also important for current and future efforts to find binary star systems that are candidates for observations with the aim of determining their orbits and component masses. ... probability of the proximity of proper motions and ; . ...

... Herschel Mission . ... Water along the outflow from a young nearby protostar: a Herschel view . ... Figure 1 shows a detailed view of the IRAS4A outflow through the comparison between the H 2 O emission and the emission from several other molecular tracers of gas with different excitation conditions: H 2 , CO(3-2), CO(14-13), and CO(6-5). The figure nicely reveals where shocks deposit energy into the molecular cloud, lighting up the water emission along the outflow . ...

We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...

. Merging cluster DLSCL J0916.2+2951 and its three matter components. Overlaid on the Hubble Space Telescope (HST) color image of the galaxies is the total mass distribution (blue) based on WL analysis of the HST images and the cluster gas distribution (red) based on Chandra X-ray observations. The bulk of the collisional gas is located between the two collisionless galaxy and mass concentrations, indicative of a dissociative merger.
