Let’s be honest: the Sun, when compared to other stars, is a pretty mediocre star. It is not very big, it is not very small. It is not very hot, it is not very cold. And it is in the middle of its life. But it is our own star, the one that gives us light and warmth, the star that gives us life. Life in planet Earth would not be possible without our Sun. In this talk we will travel through the wonders of our very own nuclear reactor. I will talk about how Earth — and indeed all of us — interacts with the Sun, about the so-called Space Weather, about the internal workings of the star and about what we still do not know about it. After one hundred years since the discovery of magnetic field in the Sun by George Ellery Hale, still many questions remain unanswered. In this context, the European Solar Telescope mega-project will help scientists to extract the smallest details of the Sun’s atmosphere and, hopefully, to give an answer to some of the long standing mysteries that surround the Sun. I will end the talk by giving a first hand insight on this 4-meter class european solar telescope that will use tomorrow’s technology to bring the Sun a little bit closer to us.
The topic of her PhD thesis was the variations on the observed solar irradiance due to magnetic activity present on the solar surface. Soon Ada moved towards observations of the Sun at very high spatial resolution and whatever spectropolarimetry techniques could tell us about the physical properties of the Sun’s atmosphere and its magnetism at the finest scales. Now she is focusing on the process of emergence of the magnetic field from the interior of the Sun upwards into the solar outer atmosphere and its effects in the Sun’s activity.
Her job has taken her to living in different places: the Rocky Mountains in Colorado (USA) for her first postdoc, Oslo (Norway), Granada (Spain) and now back to Oslo.
Ada is heavily involved in the European Solar Telescope project. She is a member of the EST Scientific Advisory Group (that will decide on the scientific questions to be tackled with EST) and has also an education & outreach component in her appointment as the scientific responsible for EST communications in Oslo.
When Ada is not scrutinizing the Sun, she can be found diving, skiing, or just enjoying the pleasures of life.
