The evolution of (A) sulfur and (B, C) HSE concentrations with time are shown with ks = 0.44 (Eq. 2). The accretion history is shown in (A-C). Results are shown for multi-stage FeS segregation (m-s) and late single-stage segregation (s-s) at 118 My. The vertical dashed lines in (A-C) show the time of the final giant impact (GI) at 113 My and the start of late veneer accretion (LV) at 119 My. Error bars, based on the propagation of uncertainties in the partitioning parameters, are shown in (B) and (C) for the final Pd and Ru concentrations; propagated uncertainties for Pt and Ir are ±0.3 and ±0.6 ppb respectively. (D) Final calculated HSE values, normalized to Ir and CI, compared with bulk silicate Earth values. https://www.sethajacobson.com/research-updates/2017/1/28/astrobites-covered-oxygen-isotopic-evidence-for-vigorous-mixing-during-the-moon-forming-giant-impact monthly 0.5 2017-10-11 https://www.sethajacobson.com/research-updates/2015/12/2/the-sublimation-driven-yorp-effect-or-syorp monthly 0.5 2017-10-11 https://images.squarespace-cdn.com/content/v1/54c51afce4b0e3768819d8d6/1449044653861-8WM8TM7685G8EXPV24WV/image-asset.jpeg Research Updates - Comet striae formation by the sublimation driven YORP effect or SYORP A cartoon of the stria formation process as hypothesized with the SYORP effect. (1) A parent chunk is disturbed and leaves the surface of the comet, (2) sublimation causes anti-sunward drift and rotationally accelerates (SYORP effect) the parent chunk, (3) the parent chunk rotationally fissions, (4) this process repeats at an increasingly rapid rate creating a fragmentation cascade, and (5) the small daughter chunks transition from sublimation to radiation pressure dominated anti-sunward drift and appear as a stria. https://www.sethajacobson.com/research-updates/2015/8/2/coverage-by-planetary-science-research-discoveries monthly 0.5 2017-10-11 https://www.sethajacobson.com/research-updates/2015/7/17/the-great-dichotomy-of-the-solar-system monthly 0.5 2017-10-11 https://images.squarespace-cdn.com/content/v1/54c51afce4b0e3768819d8d6/1437125051633-F858QVOG3JEG5RMMO24N/Plot1.png Research Updates - The Great Dichotomy of the Solar System The growth of two planetary embryos. The red embryo is exterior to the ice line and grows to 10 Earth masses while the the green embryo is interior and grows to 0.1 Earth masses. These masses are appropriate for runaway gas accretion in the outer Solar System to make Jupiter and the giant impact stage of terrestrial planet formation to make Earth. https://www.sethajacobson.com/research-updates/2017/10/11/press-coverage-for-highly-siderophile-elements-in-earths-mantle-as-a-clock-for-the-moon-forming-impact monthly 0.5 2017-10-11 https://www.sethajacobson.com/research-updates/2017/10/11/press-release-for-highly-siderophile-elements-in-earths-mantle-as-a-clock-for-the-moon-forming-impact monthly 0.5 2017-10-11 https://images.squarespace-cdn.com/content/v1/54c51afce4b0e3768819d8d6/1507759015069-GKI2X7TNOLCWQ2LM8KLK/Picture1.jpg Research Updates - Press Release for "Highly siderophile elements in Earth's mantle as a clock for the Moon-forming impact" https://www.sethajacobson.com/research-updates/category/Solar+System+Construction monthly 0.5 https://www.sethajacobson.com/research-updates/category/Popular+Press+Coverage monthly 0.5 https://www.sethajacobson.com/research-updates/category/Small+Body+Evolution monthly 0.5 https://www.sethajacobson.com/research-updates/category/Publications monthly 0.5 https://www.sethajacobson.com/research-updates/category/Scientific+Press+Coverage monthly 0.5 https://www.sethajacobson.com/research-updates/category/Planet+Formation monthly 0.5 https://www.sethajacobson.com/research-updates/category/Publication+Summary monthly 0.5 https://www.sethajacobson.com/research-updates/category/Press+Release monthly 0.5 https://www.sethajacobson.com/research-updates/tag/Mars monthly 0.5 https://www.sethajacobson.com/research-updates/tag/Mars+Trojans monthly 0.5 https://www.sethajacobson.com/research-updates/tag/Differentiated+Asteroids monthly 0.5 https://www.sethajacobson.com/research-updates/tag/Small+Bodies monthly 0.5 https://www.sethajacobson.com/research-updates/tag/Eureka monthly 0.5 https://www.sethajacobson.com/notes daily 0.75 2025-09-18 https://www.sethajacobson.com/notes/2025/9/18/msu-spartan-single-game-general-admission-ticket-prices monthly 0.5 2025-09-18 https://images.squarespace-cdn.com/content/v1/54c51afce4b0e3768819d8d6/1c5c5844-897c-4606-a5c6-85ca0790dc90/Screenshot+2025-07-24+at+12.42.44%E2%80%AFPM.png Notes - MSU Spartan Single-Game General Admission Ticket Prices - Make it stand out This is a table of the MSU Spartan Single-Game General Admission Ticket Prices with a column describing when children are free.
