Chondrule formation in the outer disk from the primary three-dimensional chemical composition of CM chondrules
Poula Eyðbjørnsdóttir, Anders Johansen, Elishevah van Kooten
Chondrules and their associated fine-grained rims record key processes in the early protoplanetary disk, yet the links between chondrule chemistry, morphology, and matrix complemen…
Chemical Abundances Shape History (CASH). I. A Link between Giant Planets Orbital Periods and Host Stellar C/O Ratios
Ruisheng Zhang, Ji-Wei Xie, Mengrui Pan +5
The chemical abundance of host stars plays a pivotal role in shaping the formation history of planetary systems, yet the influence of elements beyond iron remains poorly understood…
Locked In Ice: how Pebble Drift and Volatile Entrapment can Significantly Impact Carbon and Oxygen Ratios in Evolving Protoplanetary Discs
Joe Williams, Sebastiaan Krijt, Bertram Bitsch +2
The complex interplay between the growth, drift, and sublimation of ice-covered pebbles can strongly influence the volatile distribution and evolution of disc composition, and ther…
Infall and Disk Processes - the Message from Meteorites
François L. H. Tissot, Christoph Burkhardt, Aleksandra Kuznetsova +5
How do planetary systems, in general, and our own Solar System (SS), in particular, form? In conjunction, Astronomy and Isotope Cosmochemistry provide us with powerful tools to ans…
The cosmic journey of dust grains -- from nucleation to planetary system
Kira Lund, Anders Johansen, Oscar Agertz
Dust is essential to the evolution of galaxies and drives the formation of planetary systems. The challenge of inferring the origin of different presolar dust grains from meteoriti…
A high-resolution survey of protoplanetary disks in Lupus and the nature of compact disks
Osmar M. Guerra-Alvarado, Nienke van der Marel, Jonathan P. Williams +4
Most of the exoplanets discovered in our galaxy to date orbit low-mass stars, which tend to host small disks in their early stages. To better elucidate the link between planet form…
A primordial radius valley as a consequence of planet formation
Jesper Nielsen, Anders Johansen, Komal Bali +1
The radius distribution of close-in planets has been observed to have a bimodal distribution with a dearth of planets around ~1.5-2.0 commonly referred to as the ''radiu…
Performance of the Stellar Abundances and atmospheric Parameters Pipeline adapted for M dwarfs I. Atmospheric parameters from the spectroscopic module
Terese Olander, Matthew R. Gent, Ulrike Heiter +12
M dwarfs are important targets in the search for Earth-like exoplanets due to their small masses and low luminosities. Several ongoing and upcoming space missions are targeting M d…
The influence of dust growth on the observational properties of circumplanetary discs
Matthäus Schulik, Bertram Bitsch, Anders Johansen +1
Dust growth is often indirectly inferred observationally in star-forming environments, theoretically predicted to produce mm-sized particles in circumstellar discs, and also presum…
Dust ring and gap formation by gas flow induced by low-mass planets embedded in protoplanetary disks . Time-dependent model
Ayumu Kuwahara, Michiel Lambrechts, Hiroyuki Kurokawa +2
The observed dust rings and gaps in protoplanetary disks could be imprints of forming planets. Even low-mass planets in the one-to-ten Earth-mass regime, that do not yet carve deep…
Evolution of gas envelopes and outgassed atmospheres of rocky planets formed via pebble accretion
Piia Maria Tomberg, Anders Johansen
We present here results of numerical simulations of the formation and early evolution of rocky planets through pebble accretion, with an with an emphasis on hydrogen envelope longe…
Rotational spectroscopy of CHOD with a reanalysis of CHOD toward IRAS 162932422
V. V. Ilyushin, H. S. P. Müller, M. N. Drozdovskaya +10
We have started a measurement campaign of numerous methanol isotopologs in low-lying torsional states in order to provide extensive line lists for radio astronomical observations f…
The rotation-tunneling spectrum of 3-hydroxypropenal and confirmation of its detection toward IRAS 162932422 B
H. S. P. Müller, A. Coutens, J. K. Jørgensen +3
3-Hydroxypropenal (HOCHCHCHO) is the lower energy tautomer of malonaldehyde which displays a complex rotation-tunneling spectrum. It was detected tentatively toward the solar-type…
How the presence of a giant planet affects the outcome of terrestrial planet formation simulations
Zhihui Kong, Anders Johansen, Michiel Lambrechts +2
The architecture and masses of planetary systems in the habitable zone could be strongly influenced by outer giant planets, if present. We investigate here the impact of outer gian…
Feasibility of detecting shadows in disks induced by infall
A. Krieger, M. Kuffmeier, S. Reissl +3
Observations performed with high-resolution imaging techniques revealed the existence of shadows in circumstellar disks that can be explained by the misalignment of an inner with r…
Formation of wide-orbit giant planets in protoplanetary disks with a decreasing pebble flux
Nerea Gurrutxaga, Anders Johansen, Michiel Lambrechts +1
The presence of distant protoplanets may explain the observed gaps in the dust emission of protoplanetary disks. Here, we derive a novel analytical model to describe the temporal d…
Dust depletion of of metals from local to distant galaxies II: Cosmic dust-to-metal ratio and dust composition
Christina Konstantopoulou, Annalisa De Cia, Cédric Ledoux +10
The evolution of the cosmic dust content and the cycle between metals and dust in the interstellar medium (ISM) play a fundamental role in galaxy evolution. The chemical enrichment…
Linking ice and gas in the Coronet cluster in Corona Australis
G. Perotti, J. K. Jørgensen, W. R. M. Rocha +7
During the journey from the cloud to the disc, the chemical composition of the protostellar envelope material can be either preserved or processed to varying degrees depending on t…
Investigation of the rotational spectrum of CDOD and an astronomical search toward IRAS 162932422
V. V. Ilyushin, H. S. P. Müller, J. K. Jørgensen +8
Solar-type prestellar cores and protostars display large amounts of deuterated organic molecules. Recent findings on CHDOH and CDOH toward IRAS 16293-2422 suggest that even…
Episodic infall towards a compact disk in B335?
Per Bjerkeli, Jon P. Ramsey, Daniel Harsono +7
Previous observations of B335 have presented evidence of ongoing infall in various molecular lines, e.g., HCO, HCN, CO. There have been no confirmed observations of a rotationa…
