Fe-rich star HR 6870.

HR 710 (HD 15144): an ultra-Sr-rich, magnetic Ap star with a close companion★

The magnetic, chemically peculiar A-star HR 710 (HD 15144, ADS 1849A, AB Cet) has a close companion in a nearly circular orbit. Its 3-d period is unusually short for such stars. The system emits moderately hard X-rays, which likely come from a white dwarf secondary (ADS 1849Ab). The Sr II spectrum is very strong, and the resonance lines show similar core-nib structure to the stronger Ca K line....

The laboratory analysis of Bi II and its application to the Bi - rich HgMn star HR 7775

The bismuth spectrum emitted from a hollow cathode discharge has been recorded with a Fourier Transform Spectrometer (FTS). Accurate wavelengths have been determined for 104 Bi ii lines, and several new energy levels have been found, while the accuracy of previously known Bi ii level energies have been improved. The hyperfine structure of all observed Bi ii lines has been analyzed, yielding hyp...

The sixth frequen y of roAp star HR 1217 Margarida

A spectroscopic study of the magnetic CP - star HR 1094 ?

The chemically peculiar star HR 1094 has been investigated with respect to its chemical composition and the magnetic influence on its stellar spectrum. By using spectral lines slightly affected by the field v sin i was determined to be ≤ 17 km s −1. The iron-group elements as well as chlorine and the heavy elements platinum, gold and mercury show an overabundance compared to the sun. The analys...

RFC 6870 PW Preferential Forwarding Status Bit

This document describes a mechanism for signaling the active and standby status of redundant Pseudowires (PWs) between their termination points. A set of Redundant PWs is configured between Provider Edge (PE) nodes in single-segment pseudowire (SS-PW) applications or between Terminating Provider Edge (T-PE) nodes in Multi-Segment Pseudowire (MS-PW) applications. In order for the PE/T-PE nodes t...
