The first image of a new gaseous component in a planetary nebula.
False color image of the planetary nebula NGC 6778. In blue, the emission associated with weak lines of ion O++ recombination, taken with the OSIRIS tunable filter blue instrument in the GTC. In green, emission of the same ion in the excited lines by coll

This week, the Instituto de Astrofísica de Canarias is hosting the Second SONG Scientific Congress to conclude the first decade of high-level work of this international network devoted to the study of the interior of stars and the planetary systems that surround them. The meeting, which is taking place at the headquarters of IACTEC in La Laguna from 18 to 20 September, brings together more than 50 scientists from Europe, the United States, Australia and China to discuss the latest state-of-the-art techniques in time-resolved spectroscopy and stellar astrophysics. The Stellar Observations
Begoña García Lorenzo, a researcher at the Instituto de Astrofísica de Canarias (IAC) has been appointed coordinator of the Network of Astronomical Infrastructures (RIA), and advisory committee on astronomical affairs of the General Administration of State, funded by the Ministry of Science, Innovation and Universities. The task of the RIA is to offer guidance about the Scientific-Technical Singular Infrastructures (ICTS in Spanish) and International Installations and Organisms (IOI), promoting collaboration among them. With an important carreer lasting over two decades in astrophysical
The transient Swift J1727.8-162 is the latest member of the X-ray binary black hole family to be discovered. They are formed by a black hole and a low-mass star whose gas is stripped off and accreted to the black hole via an accretion disc. The high temperature of the accretion disc makes it shine in all energy bands up to X-rays, and is particularly bright during epochs known as outbursts. In this novel study, published just a few months after the discovery of the system, we present 20 epochs of optical spectroscopy obtained with the GTC-10.4m telescope. The spectra cover the main accretion
