GRAVITY observations reveal that most massive stars in the Orion Trapezium cluster live in multiple systems. Our deep, milliarcsecond-resolution interferometry...
Multiple stellar generations in the Large Magellanic Cloud Star Cluster NGC 1846
The recent discovery of multiple stellar populations in massive Galactic globular clusters poses a serious challenge for models of star cluster formation and...
Multiple stellar populations in Galactic globular clusters: observational evidence
An increasing number of both photometric and spectroscopic observations over the last years have shown the existence of distinct sub-populations in many...
Multiple stellar populations in the Globular Clusters NGC1851 and NGC6656 (M22).
In the last years, photometric and spectroscopic evidence has demonstrated that many, maybe all the Globular Clusters (GC) host multiple stellar populations...
Multiplicity Among Young Brown Dwarfs and Very Low Mass Stars
Characterizing multiplicity in the very low mass (VLM) domain is a topic of much current interest and fundamental importance. Here we report on a near-infrared...
Multiplicity at the Very Low Mass End of the H-R Diagram
We review the properties of multiplicity of very low mass stars and brown dwarfs in different environments and at different ages. We will compare the main...
Multipole rates for atomic polarization studies: the case of complex atoms in non-spherically symmetric states colliding with atomic hydrogen.
Interpretation of linearly polarized parameters of the spectral lines of the second solar spectrum permits to obtain information about the magnetic field vector...
Multiprocessor data acquisition system for a 256x256-pixel infrared camera
The Department of Detectors of the Instituto de Astrofisica de Canarias, Spain is developing a data acquisition system (DAS) for an infrared camera based in a...
