The dispersal of planet-forming discs: theory confronts observations

B Ercolano, I Pascucci - Royal Society Open Science, 2017 - royalsocietypublishing.org
Discs of gas and dust around million-year-old stars are a by-product of the star formation
process and provide the raw material to form planets. Hence, their evolution and dispersal …

Dust evolution and the formation of planetesimals

T Birnstiel, M Fang, A Johansen - Space Science Reviews, 2016 - Springer
The solid content of circumstellar disks is inherited from the interstellar medium: dust
particles of at most a micrometer in size. Protoplanetary disks are the environment where …

Water in star-forming regions: physics and chemistry from clouds to disks as probed by Herschel spectroscopy

EF van Dishoeck, LE Kristensen, JC Mottram… - Astronomy & …, 2021 - aanda.org
Context. Water is a key molecule in the physics and chemistry of star and planet formation,
but it is difficult to observe from Earth. The Herschel Space Observatory provided …

The radial distribution of H2 and CO in TW Hya as revealed by resolved ALMA observations of CO isotopologues

KR Schwarz, EA Bergin, LI Cleeves… - The Astrophysical …, 2016 - iopscience.iop.org
ABSTRACT CO is widely used as a tracer of molecular gas. However, there is now mounting
evidence that gas phase carbon is depleted in the disk around TW Hya. Previous efforts to …

Volatile-carbon locking and release in protoplanetary disks-A study of TW Hya and HD 100546

M Kama, S Bruderer, EF Van Dishoeck… - Astronomy & …, 2016 - aanda.org
Aims. The composition of planetary solids and gases is largely rooted in the processing of
volatile elements in protoplanetary disks. To shed light on the key processes, we carry out a …

JWST/MIRI spectroscopy of the disk of the young eruptive star EX Lup in quiescence

Á Kóspál, P Ábrahám, L Diehl, A Banzatti… - The Astrophysical …, 2023 - iopscience.iop.org
EX Lup is a low-mass pre-main-sequence star that occasionally shows accretion-related
outbursts. Here, we present JWST/MIRI medium-resolution spectroscopy obtained for EX …

A lithium depletion boundary age of 21 Myr for the Beta Pictoris moving group

AS Binks, RD Jeffries - … of the Royal Astronomical Society: Letters, 2013 - academic.oup.com
Optical spectroscopy is used to confirm membership for eight low-mass candidates in the
young Beta Pic moving group (BPMG) via their radial velocities, chromospheric activity and …

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
diagram on their way to the main sequence. These stars provide a valuable link between …
