Se descubren en el espacio interestelar moléculas clave para la formación de estructuras básicas de la vida. Se ha logrado identificar una de las moléculas de...
Demostramos que existe una población de TNOs, de la cual 2003 EL61 es el objeto de mayor tamaño, que se mueven en órbitas muy similares y cuyas superficies...
A possible explanation has been discovered for the UV peak at 2175A based on the presence of fullerenes and buckyonians in interstellar matter. This is a...
Post-common envelope binaries as the precursors of extremely red old stars
Modelling dust formation in single stars evolving through the carbon-star stage of the asymptotic giant branch (AGB) (i.e., the late evolutionary stages of Sun...
Powerful winds driven by a supermassive black hole
The supermassive black holes in the centres of galaxies have a basic influence on their evolution. This happens during a phase in which the black hole is...
Proton acceleration in thermonuclear nova explosions revealed by gamma rays
Classical novae are cataclysmic binary star systems in which the matter of a companion star is accreted on a white dwarf. Accumulation of hydrogen in a layer...
Radial variations in the stellar initial mass function of early-type galaxies.
The hypothesis of a universal initial mass function (IMF) - motivated by observations in nearby stellar systems - has been recently challenged by the discovery...
Rapid Orbital Decay in the 12.75-minute Binary White Dwarf J0651+2844.
We report the detection of orbital decay in the 12.75-minute, detached binary white dwarf (WD) SDSS J065133.338+284423.37 (hereafter J0651). Our photometric...
Rapid quasi-periodic oscillations in a relativistic jet
Active galactic nuclei (AGN) consist of a supermassive black hole fed by the circumnuclear material close to the galaxy center. Around 10% of the AGNs develop a...
