Protostars and Planets VII

Protostars & Planets VII belongs to a series of conferences to summarize the state-of-the-art in the field of star and planet formation. See you in Kyoto Japan.

40 years of #ProtostarsAndPlanets #PPVII #PP7

[Shota Notsu / 野津 翔太 @SN_star_ppd]

@AAstrochemistry Today I had a seminar talk in the MPIA PSF Coffee Seminar🇩🇪, about our ALMA molecular line observations for the V883 Ori disk. Thank you very much for many questions and comments!

Dear #PPVII participants. The amarys system will close soon. If you need to download your receipt, please do it asap since it will not be available after. https://t.co/oI3HBTgUCO

#PPVII summary in numbers: 780 participants, 647 posters from 28 regions. Thank you to all the participants for the great science display! And thank you to the SOC and LOC who made it possible.

[Protostars and Planets VII @ppvii2023]

Thank you to all the participants of #PPVII. Have a nice and safe trip back home. See you in #PPVIII #ProtostarsAndPlanets

Congratulations to the winners of the #PPVII Poster Award! Talks by Daria Dall'Ollio, Dominique M. Segura-Cox, lain MacDougall Hammond, and Yusuke Aso

Molec #IsotopicRatios to understand the evolution of matter. Understanding how they evolve is key to interpret observations in planetary/exoplanetary atmospheres.
Better treatments of ice/dust chemistry & dynamics in PPDs models & more observations in diverse environments needed.

[Protostars and Planets VII @ppvii2023]

Chapter 29 of #PPVII: The Isotopic Links from #PlanetFormingRegions to the #SolarSystem by Kenji Furuya and Martin Cordiner. Tracing material evolution with #IsotopicRatios #IsotopicFractionation #Astrochemistry #ProtostarsAndPlanets

[Protostars and Planets VII @ppvii2023]

Obs: large spectroscopic surveys. More detailed elemental accounting of CHNOPS in different environments. Theory: improve gas/dust/chemistry simulations, dynamical effects, geophysical evolution. Laboratory studies: reaction rates, ice analogs, CHNOPS mantles impact on dust/ice

[Protostars and Planets VII @ppvii2023]

Chapter 28 of #PPVII: #ChemicalHabitability: Supply and Retention of Life’s Essential Elements During #PlanetFormation by Johanna Teske and Sebastiaan Krijt #LifeOnEarth #HabitablePlanets #CHNOPS Are Exo-Earths like Earth? #ProtostarsAndPlanets

[Protostars and Planets VII @ppvii2023]

Masahiko Arakawa: Planetesimals were composed of pebbles. Streaming instability forms planetesimals of ~100 km, but direct collisions of pebbles or collisional disruption and re-accumulation are also possible. Large migrations in the disk. Multidisciplinary studies are needed

[Protostars and Planets VII @ppvii2023]

Chapter 27 of #PPVII Exploration-Based Reconstruction of #Planetesimals by Masahiko Arakawa #Asteroids and #Comets keep the information of the 1st generation planetesimals #ProtosolarDisk #DustGrowth Origin of #WaterOnEarth

[Protostars and Planets VII @ppvii2023]

Tristan: Precise measurements with #JunoMission and #Cassini (deep atmosphere & interior), but convection in H-based abyssal atmospheres is not yet understood. Accretion is favored as a formation mechanism but what is accreted (gas/solids) & the role of mixing must be studied

[Protostars and Planets VII @ppvii2023]

Chapter 26 of #PPVII #GiantPlanets from the Inside-Out by Tristan Guillot. Why study giant planets: Role in shaping #PlanetarySystems, contain gas from early conditions, as atmospheric laboratories #ProtostarsAndPlanets

[Protostars and Planets VII @ppvii2023]

Jack & William Borucki: The #KeplerMission has shown that most stars form #planets and that planets have been forming since the beginning of the Galaxy. Kepler has shown that even Earth-sized planets are common. Nevertheless, life's complexity may be a rarer phenomenon. #PPVII

[Protostars and Planets VII @ppvii2023]

Welcome to our last day of #PPVII. We start the morning session with the review of Chapter 23: #Exoplanet Science from the #Kepler mission by Jack Lissauer. Are Earth-like planets common? #ProtostarsAndPlanets #KeplerMission

[Protostars and Planets VII @ppvii2023]

Terrestrial planets start accreting first but finish last. Rocky planets form in hot magma states. Accreted metals and volatiles chemically equilibrate (core/mantle/atmosphere). Geophysical/Geochemical evolution is key. #PPVII

[Protostars and Planets VII @ppvii2023]

Chapter 25 of #PPVII #GeophysicalEvolution During #RockyPlanetFormation by Miki Nakajima and Tim Lichtenberg. Origin of the diversity of #RokyPlanets? #Meteorites #CAIs #chondrites #Planetesimals #PlanetGrowth #ProtostarsAndPlanets
