An international team of researchers, including David S. Aguado, Jonay González and Carlos Allende Prieto of the Instituto de Astrofísica de Canarias (IAC), has found a star with extremely low metallicyt, one of the oldest in the Milky Way, and for that reason an excellent messenger from the early universe.

The study, led by Paula Izquierdo, a doctoral student at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), has gone deeply into the analysis of this exceptional white dwarf, which shows periodic transits produced by fragments of a shredded planetesimal. The observations used for this research were obtained with the Gran Telescopio Canarias and with the Liverpool Telescope.

A study involving a researcher from the Instituto de Astrofísica de Canarias (IAC), which has been led by a researcher at the Instituto de Física Fundamental (IFF-CSIC) and the Instituto de Ciencias del Cosmos (UB-IEEC), argues that the explosion that Johannes Kepler observed in 1604 was caused by a merger of two stellar residues.

An international team led by a PhD student from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has identified the emission of tellurium in the infrared spectra of two planetary nebulae and bromine in one of them.

The Instituto de Astrofísica de Canarias (IAC) and the University of Oviedo present today the discovery of two new planetary systems, one of them hosting three planets with the same size of the Earth.

An international team led by researchers from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) has cataloged around 200 oscillations of the solar prominences during the first half of 2014. Its development has been possible thanks to the GONG network of telescopes, of which one of them is located in the Teide Observatory.
