09:32:42	 From Justin Dillon : I agree, that is probably also my favorite feature
09:33:08	 From Bonnie Bosworth : I use Google meets!
09:35:16	 From Jim Deane - Ottawa KS : Good to know we have options...
09:35:52	 From Justin Dillon : Would the effect of sun expansion have an effect on the asteroid belt?
09:39:28	 From Sean Kelly 🌟 : What an awesome slide!
09:39:32	 From Matteo Cantiello : https://www.fieldtestedsystems.com/ptable/
09:39:58	 From Sean Kelly 🌟 : Worth it!
09:40:07	 From Natascha Cox : awesome poster!
09:40:45	 From Justin Dillon : I just lost $40
09:40:57	 From Bryn Bishop (she/her) : Arbor has one for $30 https://www.arborsci.com/products/periodic-table-of-spectra
09:40:57	 From Sean Kelly 🌟 : @Justin me too!
09:41:25	 From Sean Kelly 🌟 : @Bryn Thank you!
09:46:40	 From Sean Kelly 🌟 : Will white dwarfs have a solid surface? A crust? Can there be interior mechanisms to allow internal material to migrate to the surface?
09:47:28	 From Dimitri Veras : Too kind JJ!
09:49:29	 From Robert Baker : why do the remaining planets expand?
09:50:04	 From woody maxwell : How do you find the chemistry of rocks falling into white dwarfs?
09:50:34	 From Dimitri Veras : @Robert: The planets expand due to conservation of angular momentum as the star loses mass to become a white dwarf.
09:53:30	 From Richard Moore : Would Earth's orbit also expand and increase as our sun expands, rather than Earth getting swallowed up into our sun?
09:55:42	 From Dimitri Veras (Warwick University) : @Richard: There will be a competition between the outward expansion of the Earth's orbit and the tidal tug of the Sun, which will draw the Earth in. This competition will be finely balanced, which is why we don't know the outcome.
09:56:34	 From Sean Kelly 🌟 : That's amazing. I've been looking forward to seeing the James Webb telescope telling us that the atmospheres of the exoplanets have water, perhaps it can now confirm this result
09:56:42	 From Richard Moore : how depressing
09:58:13	 From Sean Kelly 🌟 : Is there really no other mechanism for generating lithium? Supernovae?
09:59:50	 From Maggie Sherriffs (she/her/hers, KITP staff) : @Sean check this out: https://news.osu.edu/the-stuff-of-the-universe-keeps-changing/
10:00:36	 From Sean Kelly 🌟 : @Maggie Thanks!
10:02:12	 From Matteo Cantiello : Stars do have ways to produce Lithium (although most of the time they destroy it — Lithium is burned at relatively low temperatures). This said in stars Li is mixed with a lot of other stuff (mostly H and He). That’s why to pollute WDs efficiently you likely need planetesimal accretion
10:04:01	 From Sean Kelly 🌟 : @Matteo Thank you
