Debris Disks: Probing Planet Formation

, 2018
Debris disks are the dust disks found around ~20% of nearby main sequence stars in far-IR surveys. They can be considered as descendants of protoplanetary disks or components of planetary systems, providing valuable information on circumstellar disk ...

On planet formation in HL Tau [PDF]

, 2015
We explain the axisymmetric gaps seen in recent long-baseline observations of the HL Tau protoplanetary disc with the Atacama Large Millimetre/Submillimetre Array (ALMA) as being due to the different response of gas and dust to embedded planets in ...

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.

The Effect of Dust Evolution and Traps on Inner Disk Water Enrichment

The Astrophysical Journal, 2023
Substructures in protoplanetary disks can act as dust traps that shape the radial distribution of pebbles. By blocking the passage of pebbles, the presence of gaps in disks may have a profound effect on pebble delivery into the inner disk, crucial for ...

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

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 ...

Interstellar ices as carriers of supernova material to the early solar system

Nature Communications
Planetary materials show systematic variations in their nucleosynthetic isotope compositions that resonate with orbital distance. The origin of this pattern remains debated, limiting how these isotopic signatures can be used to trace the precursors of ...

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.

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.
