My PhD student Rachel Booth has been working on X-ray data from several space telescopes and has published our findings in MNRAS recently: X-ray emission from stars quiets down with age much more dramatically than thought before (see here for more details about the paper). Now NASA has published a press release on Rachel’s research, here is the link: https://www.nasa.gov/mission_pages/chandra/news/x-rays-reveal-temperament-of-possible-planet-hosting-stars.html. Some really nice results, and hopefully we’ll be able to collect more data soon and study this in even more detail!
