MINDS. JWST-MIRI reveals a peculiar CO-rich chemistry in the drift-dominated disk CX Tau
Marissa Vlasblom, Milou Temmink, Sierra L. Grant +20
Radial drift of icy pebbles can have a large impact on the chemistry of the inner regions of protoplanetary disks. Compact dust disks (50 au) are suggested to have a high…
Hidden under a warm blanket: If planets existed in protostellar disks, they would hardly produce observable substructures
P. Nazari, A. D. Sellek, G. P. Rosotti
The onset of planet formation is actively under debate. Recent mass measurements of disks around protostars suggest an early start of planet formation in the Class 0/I disks. Howev…
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…
MINDS. JWST-MIRI Observations of a Spatially Resolved Atomic Jet and Polychromatic Molecular Wind Toward SY Cha
Kamber R. Schwarz, Matthias Samland, Göran Olofsson +21
The removal of angular momentum from protostellar systems drives accretion onto the central star and may drive the dispersal of the protoplanetary disk. Winds and jets can contribu…
Photoevaporation of protoplanetary discs with PLUTO+PRIZMO I. Lower X-ray-driven mass-loss rates due to enhanced cooling
Andrew D. Sellek, Tommaso Grassi, Giovanni Picogna +3
Context: Photoevaporation is an important process for protoplanetary disc dispersal but there has so far been a lack of consensus from simulations over the mass-loss rates and the…
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…
Correlation between accretion rate and free-free emission in protoplanetary disks -- A multi-wavelength analysis of central mm/cm emission in transition disks
Alessia A. Rota, Jurrian D. Meijerhof, Nienke van der Marel +3
The inner regions of protoplanetary disks are the locations where most of planets are thought to form and where processes that influence the global evolution of the disk, such as M…
