    Sucessful test of new technology which should help to discover “other Earths”
    A scientific team, led by the Max Planck Institute for Quantum Optics, with participation from the Instituto de Astrofísica de Canarias, confirms the high degree of precision of the new calibration system known as a “laser frequency comb” which could be the key to the detection of planets like the Earth. The study is published in the journal Nature Astronomy.

    New edition of "Girls who broke a glass ceiling while looking at the sky"
    With the aim of motivating interest in scientific and technological (STEM) careers among the younger girls, and to publicise the work of the women astrophysicists and engineers at the IAC, in 2017 the audiovisual series "Girls who broke a glass ceiling while looking at the sky" was initiated. The series, inspired in the project "No-Nancies" by the astrophysicist Pilar Montañés is included in the project "The return of Henrietta Leavitt: from school to a research career via the theatre", an initiative of the IAC in collaboration with the Spanish Foundation for Science and Technology (FECYT)

    February 11th: an unceasing commitment to equality
    Again this year the Instituto de Astrofísica de Canarias (IAC) is showing its commitment to gender equality by organizing a large number of activities around February 11th, the International Day of Women and Girls in Science. The main aim of this day, which was declares by the General Assembly of the United Nations in 2015 is: ‘to recognize the important role that women and girls play in science and technology’ In recent years the number of women in science and technology carrees has increased significnatly. In 2017 there were six countries with more women scientists and engineers than men

  • 1D-LTE oxygen-to-iron abundance ratios [O/Fe] vs. metallicity [Fe/H] of the iron-poor star J0815+4729 (large star symbol) compared with literature measurements from the [O I] forbidden line (diamonds), the near-IR O I triplet (circles), and the near-UV OH lines (squares). The two triangles at [Fe/H] ∼ −3.6 correspond to the oxygen measurement from OH lines in the metal-poor binary stars CS 22876–032 AB (González Hernández et al. 2008).

    The extreme CNO-enhanced composition of a primitive iron-poor dwarf star
    We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high-quality data allow us to derive a metallicity of [Fe/H] = −5.49 ± 0.14 from the three strongest Fe I lines and to measure a high [Ca/Fe] = 0.75 ± 0.14. The large carbon abundance of A(C) = 7.43 ± 0.17 (or [C/Fe] ∼ 4.49 ± 0.11) places this star in the upper boundary of the low- carbon band in the A(C)–[Fe/H] diagram, suggesting no contamination from a binary AGB companion. We detect the oxygen triplet at 777 nm for the first time in an

    ROGER DAVIES: “It would be wonderful to have the TMT here in La Palma, at the Roque, and of course there would be the potential for European participation”
    He was one of the “Seven Samurai” who in 1986 published that the Milky Way, together with its neighbour galaxies, in clusters and superclusters, forms a huge concentration of matter which they named the “Great Attractor”. Today, Professor Roger Davies is the President of the European Astronomical Society (EAS), whose Board of Directors recently met at the Instituto de Astrofísica de Canarias (IAC). Davies, who is Professor at the University of Oxford, worked for many years with the William Herschel and Isaac Newton telescopes, at the Roque de los Muchachos Observatory. Because of this, he is
