We present a new method, the coupled escape probability (CEP), for exact calculation of line emission from multi-level systems, solving only algebraic equations...

PublicationA 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] =...

PublicationA 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...

PublicationA 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...

PublicationA 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...

PublicationA 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...

PublicationA new radio census of neutron star X-ray binaries
We report new radio observations of a sample of 36 neutron star (NS) X-ray binaries, more than doubling the sample in the literature observed at current-day...

PublicationA new reference catalogue for the very metal-poor Universe: +150 OB stars in Sextans A
Local Group (LG) very metal-poor massive stars are the best proxy for the First Stars of the Universe and fundamental to modelling the evolution of early...

PublicationA new spectroscopic analysis of the massive O + O type binary HD 54662 AB
HD 54662 AB is one of the three O + OB binaries known so far with orbital period longer than 1000 d, offering the opportunity to test scenarios of massive star...
