[HTML][HTML] The external photoevaporation of planet-forming discs

AJ Winter, TJ Haworth - The European Physical Journal Plus, 2022 - Springer
Planet-forming disc evolution is not independent of the star formation and feedback process
in giant molecular clouds. In particular, OB stars emit UV radiation that heats and disperses …

Herbig Stars: A Quarter Century of Progress

SD Brittain, I Kamp, G Meeus, RD Oudmaijer… - Space Science …, 2023 - Springer
Abstract Herbig Ae/Be stars are young contracting stars on the radiative track in the HR

[HTML][HTML] Water in the terrestrial planet-forming zone of the PDS 70 disk

G Perotti, V Christiaens, T Henning, B Tabone… - Nature, 2023 - nature.com
Terrestrial and sub-Neptune planets are expected to form in the inner (less than 10 au)
regions of protoplanetary disks. Water plays a key role in their formation,–, although it is yet …

[HTML][HTML] Stellar and substellar companions from Gaia EDR3-Proper-motion anomaly and resolved common proper-motion pairs

P Kervella, F Arenou, F Thévenin - Astronomy & Astrophysics, 2022 - aanda.org
Context. The multiplicity fraction of stars, down to the substellar regime, is a parameter of
fundamental importance for stellar formation, evolution, and planetology. The census of …

Detecting exomoons from radial velocity measurements of self-luminous planets: application to observations of HR 7672 B and future prospects

JB Ruffio, K Horstman, D Mawet… - The Astronomical …, 2023 - iopscience.iop.org
The detection of satellites around extrasolar planets, so called exomoons, remains a largely
unexplored territory. In this work, we study the potential of detecting these elusive objects …

A two-stage formalism for common-envelope phases of massive stars

R Hirai, I Mandel - The Astrophysical Journal Letters, 2022 - iopscience.iop.org
We propose a new simple formalism to predict the orbital separations after common-
envelope phases with massive-star donors. We focus on the fact that massive red …

Anisotropic infall and substructure formation in embedded disks

A Kuznetsova, J Bae, L Hartmann… - The Astrophysical …, 2022 - iopscience.iop.org
The filamentary nature of accretion streams found around embedded sources suggests that
protostellar disks experience heterogenous infall from the star-forming environment …

Sulphur monoxide emission tracing an embedded planet in the HD 100546 protoplanetary disk

AS Booth, JD Ilee, C Walsh, M Kama, L Keyte… - Astronomy & …, 2023 - aanda.org
Molecular line observations are powerful tracers of the physical and chemical conditions
across the different evolutionary stages of star, disk, and planet formation. The high angular …
