Letter to the Editor Emission lines in the spectra of late-B type stars
We report detections of weak emission lines in the red spectral region of sharp-lined chemically normal and peculiar (HgMn) late-B type stars from high spectral resolution and high signal-to-noise data. Most emission lines originate from high-excitation states of the ions Cr II and Mn II, with others likely to be attributed to Ti II and Fe II. The emission is observed to extend over the entire ...
متن کاملA catalogue of symbiotic stars
We present a new catalogue of symbiotic stars. In our list we include 188 symbiotic stars as well as 28 objects suspected of being symbiotic. For each star, we present basic observational material: coordinates, V and K magnitudes, ultraviolet (UV), infrared (IR), X-ray and radio observations. We also list the spectral type of the cool component, the maximum ionization potential observed, refere...
متن کاملMSC - a catalogue of physical multiple stars
The MSC catalogue contains data on 612 physical multiple stars of multiplicity 3 to 7 which are hierarchical with few exceptions. Orbital periods, angular separations and mass ratios are estimated for each subsystem. Orbital elements are given when available. The catalogue can be accessed through CDS (Strasbourg). Half of the systems are within 100 pc from the Sun. The comparison of the periods...
متن کاملEmission Lines in X-ray Spectra of Clusters of Galaxies
Emission lines in X–ray spectra of clusters of galaxies reveal the presence of heavy elements in the diffuse hot plasma (the Intra Cluster Medium, or ICM) in virial equilibrium in the dark matter potential well. The relatively simple physical state of the ICM allows us to estimate, with good accuracy, its thermodynamical properties and chemical abundances. These measures put strong constraints ...
متن کاملIdentification of the 4486 , 4504 Å emission lines in O - type spectra
Inspired by an appeal to the community fromWalborn (these proceedings) we decided to solve the long-standing problem concerning the nature of the 4486, 4504Å emission lines, which are frequently observed in O-type spectra and which are particularly prominent in supergiants. We claim that these lines emerge from sulfur, namely by deexcitation of a highly excited S IV doublet state. We prove this...
