Migration and giant planet formation

, 2004
We extend the core-accretion model of giant gaseous planets by Pollack et al. (\cite{P96}) to include migration, disc evolution and gap formation. Starting with a core of a fraction of an Earth's mass located at 8 AU, we end our simulation with the onset

Planet Formation Imager (PFI): Introduction and Technical Considerations [PDF]

, 2014
Complex non-linear and dynamic processes lie at the heart of the planet formation process. Through numerical simulation and basic observational constraints, the basics of planet formation are now coming into focus.

Interior dynamics of envelopes around disk-embedded planets

Astronomy & Astrophysics
In the core accretion scenario, forming planets start to acquire gaseous envelopes while accreting solids. Conventional 1D models assume envelopes to be static and isolated.

Inside-out Planet Formation. IV. Pebble Evolution and Planet Formation Timescales [PDF]

The Astrophysical Journal, 2018
Abstract Systems with tightly packed inner planets (STIPs) are very common. Chatterjee & Tan proposed Inside-out Planet Formation (IOPF), an in situ formation theory, to explain these planets. IOPF involves sequential planet formation from pebble-rich rings that are fed from the outer disk and trapped at the pressure maximum ...

From planetesimals to planets with N-body simulations in the giant-planet formation region

Astronomy & Astrophysics
The cores of wide-orbit giant planets can form via pebble accretion if large planetesimals form in the outer regions of protoplanetary discs at sufficiently early times.

Revisiting Collisional Dust Growth in Class 0/I Protostellar Disks: Sweep-up Can Convert a Few 10 M ⊕ of Dust into Kilogram Pebbles in 0.1 Myr

The Astrophysical Journal, 2023
Recent observations suggest that the first stages of planet formation likely take place in the Class 0/I phase of young stellar object evolution, when the star and the disk are still embedded in an infalling envelope.

Overcoming migration during giant planet formation

, 2007
In the core accretion model, gas giant formation is a race between growth and migration; for a core to become a jovian planet, it must accrete its envelope before it spirals into the host star.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
