HD 80606: Searching the chemical signature of planet formation [PDF]
, 2015 (Abridged) Binary systems with similar components are ideal laboratories which allow several physical processes to be tested, such as the possible chemical pattern imprinted by the planet formation process. Aims.

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 ...

Pebble-driven planet formation for TRAPPIST-1 and other compact systems [PDF]
Astronomy & Astrophysics, 2019 Recently, seven Earth-sized planets were discovered around the M-dwarf star TRAPPIST-1. Thanks to transit-timing variations, the masses and therefore the bulk densities of the planets have been constrained, suggesting that all TRAPPIST-1 planets are ...

Long-Period Giant Companions to Three Compact, Multiplanet Systems [PDF]
, 2019 Understanding the relationship between long-period giant planets and multiple smaller short-period planets is critical for formulating a complete picture of planet formation. This work characterizes three such systems. We present Kepler-65, a system with

Evidence for the start of planet formation in a young circumstellar disk [PDF]
Nature Astronomy, 2018 The growth of dust grains in protoplanetary disks is a necessary first step towards planet formation1. This growth has been inferred from observations of thermal dust emission2 towards mature protoplanetary systems (age >2 million years) with masses that

Evidence of an Upper Bound on the Masses of Planets and Its Implications for Giant Planet Formation [PDF]
, 2018 Celestial bodies with a mass of have been found orbiting nearby stars. It is unknown whether these objects formed like gas-giant planets through core accretion or like stars through gravitational instability.

Connecting planet formation and astrochemistry [PDF]
Astronomy & Astrophysics, 2019 To understand the role that planet formation history has on the observable atmospheric carbon-to-oxygen ratio (C/O) we have produced a population of astrochemically evolving protoplanetary disks.

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.

The Delivery of Water During Terrestrial Planet Formation [PDF]
Space Science Reviews, 2018 The planetary building blocks that formed in the terrestrial planet region were likely very dry, yet water is comparatively abundant on Earth. Here we review the various mechanisms proposed for the origin of water on the terrestrial planets.

Formation of terrestrial planet cores inside giant planet embryos
, 2010 Giant planet embryos are believed to be spawned by gravitational instability in massive extended (R ~ 100 AU) protostellar discs. In a recent paper we have shown that dust can sediment inside the embryos, as argued earlier by Boss (1998) in a slightly ...
