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. They were followed by Manuel collados, coordinator of the European SOLARNET programme, which provides the framework for the meeting. In his talk this IAC researcher explained the guidelines of the

“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

The so-called extreme trans-Neptunian objects (ETNOs) are orbiting the Sun at heliocentric distances larger than 150 AUs, and their discovery a decade ago was soon recognized as a turning point in our knowledge of the outer Solar System. The currently tally stands at 21 ETNOs, and only one, Sedna, has been spectroscopically observed. In the last years several studies have suggested that the dynamical properties of the ETNOs could be better explained if one or several planets of several Earth masses are orbiting the Sun at hundreds of AUs. In 2016, Brown and Batygin used the orbits of seven
