[HTML][HTML] Empirical constraints on turbulence in proto-planetary discs

GP Rosotti - New Astronomy Reviews, 2023 - Elsevier
Proto-planetary discs, the birth environment of planets, are an example of a structure
commonly found in astrophysics, accretion discs. Identifying the mechanism responsible for …

The interstellar interlopers

D Jewitt, DZ Seligman - Annual Review of Astronomy and …, 2023 - annualreviews.org
Interstellar interlopers are bodies formed outside of the Solar System but observed passing
through it. The first two identified interlopers, 1I/'Oumuamua and 2I/Borisov, exhibited …

Flow of gas detected from beyond the filaments to protostellar scales in Barnard 5

MT Valdivia-Mena, JE Pineda, DM Segura-Cox… - Astronomy & …, 2023 - aanda.org
Context. The infall of gas from outside natal cores has proven to feed protostars after the
main accretion phase (Class 0). This changes our view of star formation to a picture that …

Grain-size measurements in protoplanetary disks indicate fragile pebbles and low turbulence

H Jiang, E Macías, OM Guerra-Alvarado… - Astronomy & …, 2024 - aanda.org
Context. Constraining the turbulence level and pebble size in protoplanetary disks is an
essential initial step in understanding the aerodynamic properties of pebbles, which are …

Large Myr-old Disks are Not Severely Depleted of gas-phase CO or carbon

I Pascucci, BN Skinner, D Deng, M Ruaud… - The Astrophysical …, 2023 - iopscience.iop.org
We present an ACA search for [C i] 1–0 emission at 492 GHz toward large T Tauri disks (gas
radii≳ 200 au) in the∼ 1–3 Myr-old Lupus star-forming region. Combined with Atacama …

UV-driven chemistry as a signpost of late-stage planet formation

JK Calahan, EA Bergin, AD Bosman, EA Rich… - Nature …, 2023 - nature.com
The chemical reservoir within protoplanetary disks has a direct impact on planetary
compositions and the potential for life. A long-lived carbon-and nitrogen-rich chemistry at …

Porous Dust Particles in Protoplanetary Disks: Application to the HL Tau Disk

S Zhang, Z Zhu, T Ueda, A Kataoka… - The Astrophysical …, 2023 - iopscience.iop.org
Dust particle sizes constrained from dust continuum and polarization observations by radio
interferometry are inconsistent by at least an order of magnitude. Motivated by porous dust …

Testing external photoevaporation in the σ-Orionis cluster with spectroscopy and disk mass measurements

K Maucó, CF Manara, M Ansdell, G Bettoni… - Astronomy & …, 2023 - aanda.org
Context. The evolution of protoplanetary disks is regulated by an interplay of several
processes, either internal to the system or related to the environment. As most of the stars …

Planet formation—Observational constraints, physical processes, and compositional patterns

C Mordasini, R Burn - Reviews in Mineralogy and …, 2024 - pubs.geoscienceworld.org
A general theory of planet formation has been a topic of intense study over many years. The
interest in such a theory emerges naturally from asking the question of where our planet …

Planetary population synthesis and the emergence of four classes of planetary system architectures

A Emsenhuber, C Mordasini, R Burn - The European Physical …, 2023 - epjplus.epj.org
Planetary population synthesis is a helpful tool to understand the physics of planetary
system formation. It builds on a global model, meaning that the model has to include a …
