Transition disks: the observational revolution from SEDs to imaging
N van der Marel - The European Physical Journal Plus, 2023 - epjplus.epj.org
Protoplanetary disks surrounding young stars are the birth place of planets. Of particular
interest are the transition disks with large inner dust cavities of tens of au, hinting at the …

Constraining the Nature of the PDS 70 Protoplanets with VLTI/GRAVITY∗
We present K-band interferometric observations of the PDS 70 protoplanets along with their
host star using VLTI/GRAVITY. We obtained K-band spectra and 100 μas precision …

Creating the radius gap without mass loss
The observed exoplanet population features a gap in the radius distribution that separates
the smaller super-Earths (≲ 1.7 Earth radii) from the larger sub-Neptunes (∼ 1.7–4 Earth …

Can stellar-mass black hole growth disrupt disks of active galactic nuclei? The role of mechanical feedback
Stellar-mass BHs (sBHs) are predicted to be embedded in active galactic nucleus (AGN)
disks owing to gravitational drag and in situ star formation. However, we find that, due to a …

The impermanent fate of massive stars in AGN discs
M Ali-Dib, DNC Lin - Monthly Notices of the Royal Astronomical …, 2023 - academic.oup.com
Stars are likely to form or to be captured in active galactic nucleus (AGN) discs. Their mass
reaches an equilibrium when their rate of accretion is balanced by that of wind. If the …

3D global simulations of accretion onto gap-opening planets: implications for circumplanetary disc structures and accretion rates
We perform a series of 3D simulations to study the accretion of giant planet embedded in
protoplanetary discs (PPDs) over gap-opening time-scales. We find that the accretion mass …

The maximum accretion rate of a protoplanet: how fast can runaway be?
The hunt is on for dozens of protoplanets hypothesized to reside in protoplanetary discs with
imaged gaps. How bright these planets are, and what they will grow to become, depend on …

Stellar evolution in the disks of active Galactic nuclei produces rapidly rotating massive stars
Stars can either be formed in or captured by the accretion disks in active galactic nuclei
(AGNs). These AGN stars are irradiated and subject to extreme levels of accretion, which …

Accretion onto Stars in the Disks of Active Galactic Nuclei
Disks of gas accreting onto supermassive black holes are thought to power active galactic
nuclei (AGN). Stars may form in gravitationally unstable regions of these disks, or may be …

An ALMA survey of λ orionis disks: from supernovae to planet formation
Protoplanetary disk surveys by the Atacama Large Millimeter/submillimeter Array (ALMA)
are now probing a range of environmental conditions, from low-mass star-forming regions …
