SUMMARY:Physics & Astronomy Colloquium – Dr. Meredith MacGregor
LOCATION:Online
DESCRIPTION:The Department of Physics and Astronomy invites you to a colloquium featuring Dr. Meredith MacGregor, University of Colorado Boulder. Dr. MacGregor will present her talk, “How to Form a Habitable Planet” via Zoom.\n\nMeet the speaker at 3:10 p.m. - join us in welcoming the speaker and for an informal chat!\n\nhttps://wsu.zoom.us/j/91067075085?pwd=RUZtZnhEVTUrcFoxM0tOL01iODRtZz09\n\nMeeting ID: 910 6707 5085\n\nPasscode: PhysAstro\n\nAbstract: More than 20% of nearby main sequence stars are surrounded by debris disks, where planetesimals, larger bodies similar to asteroids and comets in our own Solar System, are ground down through collisions. The resulting dusty material is directly linked to any planets in the system, providing an important probe of the processes of planet formation and subsequent dynamical evolution. The Atacama Large Millimeter/submillimeter Array (ALMA) has revolutionized our ability to study planet formation, allowing us to see planets forming in disks and sculpting the surrounding material in high resolution. I will present highlights from ongoing work using ALMA and other facilities that explores how planetary systems form and evolve by (1) connecting debris disk structure to sculpting planets, (2) probing the properties of material in debris disks, and (3) understanding the impact of stellar flares on planetary habitability. Together these results provide an exciting foundation to investigate the evolution of planetary systems through multi‐wavelength observations.\n\nphysics.wsu.edu/colloquium
