Follow-up observations of binary ultra-cool dwarfs
Context: Astrometric observations of resolved binaries provide estimates of orbital periods and will eventually lead to measurement of dynamical masses. Only a...
Forecasting the success of the WEAVE Wide-Field Cluster Survey on the extraction of the cosmic web filaments around galaxy clusters
Next-generation wide-field spectroscopic surveys will observe the infall regions around large numbers of galaxy clusters with high sampling rates for the first...
Fornax 3D project: Automated detection of planetary nebulae in the centres of early-type galaxies and first results
Extragalactic planetary nebulae (PNe) are detectable through relatively strong nebulous [O III] emission and act as direct probes into the local stellar...
Four winters of photometry with ASTEP South at Dome C, Antarctica
Context. Dome C in Antarctica is a promising site for photometric observations thanks to the continuous night during the Antarctic winter and favorable weather...
Fourier method of determining the rotational velocities in OB stars
Aims:We present a comprehensive study that applies the Fourier transform to a sample of O and early B-type stars (either dwarfs, giants, or supergiants) to...
FRIDA: Near Infrared Imager and Integral Field Spectroscopy for GTC
FRIDA (inFRrared Imager and Dissector for the Adaptive optics system of the Gran Telescopio Canarias) is being designed as a diffraction limited instrument with...
From dense hot Jupiter to low-density Neptune: The discovery of WASP-127b, WASP-136b, and WASP-138b
We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18±0.02 MJ and radius 1.37±0.04...
From gas to stars: MUSEings on the internal evolution of IC 1613
Context. The kinematics and chemical composition of stellar populations of different ages provide crucial information on the evolution of the various components...
From stellar to planetary composition: Galactic chemical evolution of Mg/Si mineralogical ratio
Aims: The main goal of this work is to study element ratios that are important for the formation of planets of different masses. Methods: We study potential...
