SUMMARY:Seminar - Anders Johansen
DESCRIPTION:Speaker: ANDERS JOHANSEN\, UNIVERSITY OF COPENHAGEN \nTitle: Formation of terrestrial planets by pebble accretion \nAbstract: \nThe formation of the terrestrial planets in the Solar System is normally considered to last several 10s of million years and to have proceeded by giant impacts within a population of Mars-sized protoplanets. Observations of protoplanetary discs around young stars reveal that such discs host several hundred Earth masses of mm-cm sized pebbles. This inspired the pebble accretion theory for planet formation where the cores of giant planets grow by rapid accretion of these pebbles. By extension\, pebble accretion should be an important process in terrestrial planet formation as well. I present a series of new papers where we show that Venus\, Earth and Mars likely formed within 3-5 Myr by rapid pebble accretion. Volatiles such as water\, nitrogen and carbon are delivered by small pebbles that are accreted at the earliest stages of planetary growth. Partition of these volatiles between core\, mantle and atmosphere combined with early atmospheric loss gives good matches to the modern atmospheres and water reservoirs of Venus\, Earth and Mars. Pebble accretion thus gives a quantitive prediction of volatile budgets and atmospheric compositions of terrestrial planets without invoking stochastic giant impacts as the delivery source.\n\n\n\nZoom Meeting Details: \n\nRegister in advance for this webinar (registration is required for the first attendance only\, you will then be automatically registered for all the following seminars.:\nhttps://riceuniversity.zoom.us/webinar/register/WN_vECxt9E3S_K1QS8zejzl3w\n\n\nLink provided in the registration confirmation email\nPassword: CLEVER

SUMMARY:Seminar - Max Collinet
DESCRIPTION:Speaker: MAX COLLINET\, GERMAN AEROSPACE CENTER (DLR)\, BERLIN \nTitle: Achondrites as witnesses of early melting processes in planetesimals and planetary embryos: experimental constraints and new meteorite discoveries \nAbstract:\nAchondrite meteorites are highly variable in composition: some are ultramafic (primitive achondrites) while others are basaltic (e.g. eucrites and angrites)\, to trachy-andesitic (e.g. GRA 06128 and Erg Chech 002). Those different groups correspond to the mantle and crust of planetary building blocks\, respectively. They represent a unique opportunity to constrain the early melting processes that affected planetesimals and could have influenced the final composition of planets. \nI will describe two sets of low pressure (20-120 bars) melting experiments on chondritic compositions\, simulating batch and fractional melting (0-30 wt.% melting). They are the first experiments in which the alkali elements were retained successfully during melting at low pressure. By comparing the experimental results with the meteorite record\, I will argue that the melting processes\, and the efficiency of melt extraction\, varied greatly in achondrite parent bodies but that all planetesimals from the inner solar system (i.e. the non-carbonaceous reservoir) were initial rich in alkalis and other moderately volatile elements. The efficient extraction of silicate melts from the ureilite parent body suggest that highly volatile elements were also present during partial melting. \n\n\nZoom Meeting Details: \n\nRegister in advance for this webinar (registration is required for the first attendance only\, you will then be automatically registered for all the following seminars.:\nhttps://riceuniversity.zoom.us/webinar/register/WN_vECxt9E3S_K1QS8zejzl3w\n\n\nLink provided in the registration confirmation email\nPassword: CLEVER
