Title: Imagining Other Worlds: How Planet-Forming Disks Can Shed Light on What is Possible
The last decade of ALMA has transformed our view of planet-forming environments in all respects. High resolution images have revealed a diverse array of structured belts of millimeter-sized dust and a variety of distinct molecular compositions both within disks and between different disk systems. How does this diversity translate into the initial conditions for the formation of planets and the compositions (gas and solid) that they receive? Are planets likely to receive water and organic material at formation, or at some later phase from a belt of volatile-rich icy comets? I will present recent work including on-going efforts from the ALMA "Disk-Exoplanet C/Onnection" Large Program highlighting how our picture of the chemical and physical environment of planet formation has radically shifted in recent years and how multiwavelength observational campaigns, including new observations with JWST, can help us identify patterns in the apparent variety of protoplanetary environments.
In-person colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer Dr. Richard Mushotzky. Lunch will normally be reserved for the speaker to talk to graduate students. Anyone asking a question during a talk is asked to raise their hand and be acknowledged before speaking. Contact Dr. Richard Mushotzky for details.
