    This morning the IV SOLARNET meeting "The Sun from its interior to its outer atmosphere" organized by the Instituto de Astrofísica de Canarias (IAC) began, in Arrecife (Lanzarote). The conference was inaugurated by the IAC researchers Elena Khomenko and Marian Martínez, respectively the chair and co-chair of the Scientific Committe, who are experts in Solar Physics, and welcomed the participants.

    “With TIMER we could demonstrate a very beautiful idea: If we measure the ages of the stars that were born in the bar via the secular evolution processes, we can estimate when the galactic disc settled into a dynamically mature state” “In order to understand well how galaxies came to be the way we observe them today we must understand well the effects driven by bars” “With the TIMER demonstration programme we have already shown for one galaxy that secular evolution started 10 billion years ago, and that the structure thus formed is actually old” By Elena Mora (IAC) On nights which are

    We report the discovery of a new super-Earth orbiting the nearby cool dwarf star GJ 625 in the inner edge of the habitable zone. This result has been achieved thanks to the analysis of the radial velocity (RV) time series from the HARPS-N spectrograph, in particular, 151 HARPS-N measurements taken over 3.5 yr. The planet GJ 625 b has a mass of roughly 2.8 Earth masses and an orbital period of ~14.6 days at a distance of ~0.08 AU of its host star. The star GJ 625 is a low-activity M dwarf star located at 6.5 pc (~21 light years) from the Sun, with a stellar rotation period in the range 75-85
