A near/mid infrared search for ultra-bright submillimetre galaxies: Searching for Cosmic Eyelash Analogues
We present results from a near-/mid-IR search for submillimetre galaxies over a region of 6230 deg2 of the southern sky. We used a cross-correlation of the...
A new distance to the Brick, the dense molecular cloud G0.253+0.016
We analyse the near-infrared colour-magnitude diagram of a field including the giant molecular cloud G0.253+0.016 (a.k.a. The Brick) observed at high spatial...
We present a new method, the coupled escape probability (CEP), for exact calculation of line emission from multi-level systems, solving only algebraic equations...
A new L dwarf member of the moderately metal poor triple system HD 221356
We report on the discovery of a fourth component in the HD 221356 star system, previously known to be formed by an F8V, a slightly metal poor primary ([Fe/H] =...
A new look inside planetary nebula LoTr 5: a long-period binary with hints of a possible third component
LoTr 5 is a planetary nebula with an unusual long-period binary central star. As far as we know, the pair consists of a rapidly rotating G-type star and a hot...
A new method of determining the inclination angle in interacting binaries
We describe a method of determining the system parameters in non-eclipsing interacting binaries. We find that the extent to which an observer sees the shape of...
A new method of measuring centre-of-mass velocities of radially pulsating stars from high-resolution spectroscopy
We present a radial velocity analysis of 20 solar neighbourhood RR Lyrae and three Population II Cepheid variables. We obtained high-resolution, moderate-to...
A new non-convex model of the binary asteroid (809) Lundia obtained with the SAGE modelling technique
We present a new non-convex model of the binary asteroid (809) Lundia. A SAGE (Shaping Asteroids with Genetic Evolution) method using disc-integrated photometry...
