Erg Chech (EC) 002 is a meteorite with andesitic composition, potentially recording the lava crystallization and crust formation of its parent body. Nucleosynthetic Cr isotope composition (ε54Cr = −0.35 ± 0.06) for EC 002 suggests a non-carbonace

Within our program of physical characterization of trans-Neptunian objects and centaurs, we predicted a stellar occultation by the centaur (54598) Bienor to occur on January 11, 2019, with good observability potential. We obtained high accuracy astro

Autor: Anders Johansen, Thomas Ronnet, Martin Schiller, Zhengbin Deng, Martin Bizzarro

Publikováno v: Johansen, A, Ronnet, T, Schiller, M, Deng, Z & Bizzarro, M 2023, ' Anatomy of rocky planets formed by rapid pebble accretion : II. Differentiation by accretion energy and thermal blanketing ', Astronomy and Astrophysics, vol. 671, A75 . https://doi.org/10.1051/0004-6361/202142142

We explore the heating and differentiation of rocky planets that grow by rapid pebble accretion. Our terrestrial planets grow outside of the ice line and initially accrete 28\% water ice by mass. The accretion of water stops after the protoplanet rea

Context. Ultrahot (>1500 K) rocky exoplanets may be covered by a magma ocean, resulting in the formation of a vapor rich in rocky components (e.g., Mg, Si, Fe) with a low total pressure and high molecular mass. However, exoplanets may have also captu

Disc population synthesis:Decrease in the solid mass reservoir through pebble drift

Autor: J. Appelgren, M. Lambrechts, N. van der Marel

Publikováno v: Appelgren, J, Lambrechts, M & van der Marel, N 2023, ' Disc population synthesis : Decrease in the solid mass reservoir through pebble drift ', Astronomy & Astrophysics, vol. 673, A139 . https://doi.org/10.1051/0004-6361/202245252

Surveys of star-forming regions reveal that the dust mass of protoplanetary discs decreases by several orders of magnitude on a timescale of a few million years. This decrease in the mass budget of solids is likely due to the gas-drag-induced radial
