We present spectroscopic observations of the type 2 quasar SDSS J11311.05+162739.5 (z= 0.1732), which has the richest spectrum of forbidden high-ionization lines (FHILs, e.g. [Fe VII], [Fe X], [Fe XI] and [Ne V]) yet reported for an active galactic nucleus (AGN), as well as unusually strong [O III] λ4363 emission. The study of this object provides

We have reduced the data taken with the Spectral and Photometric Imaging Receiver (SPIRE) photometer on board the Herschel Space Observatory in the Science Demonstration Phase (SDP) of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). We describe the data reduction, which poses specific challenges, both because of the large number

We have discovered a new rapidly oscillating Ap (roAp) star among the Kepler mission target stars, KIC 10195926. This star shows two pulsation modes with periods that are amongst the longest known for roAp stars at 17.1 and 18.1 min, indicating that the star is near the terminal-age main sequence. The principal pulsation mode is an oblique dipole

The number of brown dwarfs (BDs) now identified tops 700. Yet our understanding of these cool objects is still lacking, and models are struggling to accurately reproduce observations. What is needed is a method of calibrating the models, BDs whose properties (e.g. age, mass, distance, metallicity) that can be independently determined can provide
