JWST/MIRI Reveals the Evolution from Molecular to Atomic Disk Winds
Naman S. Bajaj, Ilaria Pascucci, Sylvie Cabrit +10
The evolution and dispersal of protoplanetary disks--governed by accretion, magnetically launched jets and winds, and photoevaporative winds--fundamentally shape planetary systems.…
The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): VII. Testing accretion mechanisms from disk population synthesis
Benoît Tabone, Giovanni P. Rosotti, Leon Trapman +24
The architecture of planetary systems depends on the evolution of the disks in which they form. In this work, we develop a population synthesis approach to interpret the AGE-PRO me…
JWST captures a sudden stellar outburst and inner disk wall destruction
Chengyan Xie, Ilaria Pascucci, Dingshan Deng +6
We present JWST/MIRI observations of T~Cha, a highly variable (3-5\,mag) accreting Sun-like star surrounded by a disk with a large (\,au) dust gap. We find that t…
Modeling JWST MIRI-MRS Observations of T Cha: Mid-IR Noble Gas Emission Tracing a Dense Disk Wind
Andrew D. Sellek, Naman S. Bajaj, Ilaria Pascucci +8
[Ne II] 12.81 emission is a well-used tracer of protoplanetary disk winds due to its blueshifted line profile. MIRI-MRS recently observed T Cha, detecting this line a…
JWST MIRI/MRS Observations of T Cha: Discovery of a Spatially Resolved Disk Wind
Naman S. Bajaj, Ilaria Pascucci, Uma Gorti +8
Understanding when and how circumstellar disks disperse is crucial to constrain planet formation and migration. Thermal winds powered by high-energy stellar photons have long been…
Deserts and pile-ups in the distribution of exoplanets due to photoevaporative disc clearing
R. D. Alexander, I. Pascucci
We present models of giant planet migration in evolving protoplanetary discs. We show that disc clearing by EUV photoevaporation can have a strong effect on the distribution of gia…
The Photoevaporative Wind from the Disk of TW Hya
I. Pascucci, M. Sterzik, R. D. Alexander +6
Photoevaporation driven by the central star is expected to be a ubiquitous and important mechanism to disperse the circumstellar dust and gas from which planets form. Here, we pres…
Evidence for Disk Photoevaporation Driven by the Central Star
Ilaria Pascucci, Michael Sterzik
The lifetime of isolated protoplanetary disks is thought to be set by the combination of viscous accretion and photoevaporation driven by stellar high-energy photons. Observational…
