An Observational Study of Line-Profile Variable B-stars in Multiple Systems
We present the results of an observational study of the pulsational behavior of the line-profile variable binary components of κ Sco, λ Sco and ɛ Lup. Our...
An observational test to planet formation theories around low-mass stars
Planets smaller than Neptune are ubiquitous in the Galaxy and those around M stars constitute the bulk of warm and temperate worlds amenable for detailed...
An Observer's Guide to Build a Control Sample for Galaxy Pairs
We propose a method to build a suitable control sample (CS) in order to isolate the effect of galaxy interactions by using mock galaxy catalogues. This analysis...
Continuum subtracted dereddened images in several emission lines reveal the existence of an extended bipolar shell around η Carinae. It is best seen in the...
An Optical Intermediate Dispersion Spectrograph for the GTC
ODIN is an international consortium constituted to design and build a first-light multi-purpose optical intermediate dispersion spectrograph for the Gran...
An optical spectroscopic study of a LLQSOs sample and the impact of the aperture effect on its classification
Low Luminosity Quasi Stellar Objects comprise key objects in the context of galaxy evolution scenarios. They may represent the transition population between...
