Parallaxes and physical properties of 11 mid-to-late T dwarfs
Aims: We present parallaxes of 11 mid-to-late T dwarfs observed in the UKIRT Infrared Deep Sky Survey. We use these results to test the reliability of model...
Parallaxes of Five L Dwarfs with a Robotic Telescope
We report the parallax and proper motion of five L dwarfs obtained with observations from the robotic Liverpool Telescope. Our derived proper motions are...
Parallel tracks in infrared versus X-ray emission in black hole X-ray transient outbursts: a hysteresis effect?
We report the discovery of a new hysteresis effect in black hole X-ray binary state transitions, that of the near-infrared (NIR) flux (which most likely...
Parameter estimates for the orbits of M 32 and NGC 205 about the centre of mass of the M 31 system
The authors used simple kinematic, dynamic and geometrical assumptions to infer the orbital parameters of M32 and NGC 205 about M31. They find that both...
Parameters of the eclipsing binary α Draconis observed by TESS and SONG
We present an analysis of the eclipsing single-lined spectroscopic binary system α Dra based on photometry from the Transiting Exoplanet Survey Satellite (TESS)...
Parsec-scale Dust Emission from the Polar Region in the Type 2 Nucleus of NGC 424
Advancements in infrared (IR) interferometry open up the possibility to spatially resolve active galactic nuclei (AGNs) on the parsec-scale level and study the...
Partially ionized plasmas are found across the Universe in many different astrophysical environments. They constitute an essential ingredient of the solar...
Particle acceleration in low-power hotspots: modelling the broad-band spectral energy distribution
The acceleration and radiative processes active in low-power radio hotspots are investigated by means of new deep near-infrared (NIR) and optical Very Large...
