The majority of hot Jupiters formed beyond the water ice line
Yaxing He, Bertram Bitsch, Adrien Houge +2
Atmospheric compositions of giant exoplanets can retain information about their formation environments, as volatile species condense at different temperatures in protoplanetary dis…
JWST/MIRI Hydrocarbon and Water Absorption in the Wind of a Young Disk: Signatures of Pebble Drift and Carbon Grain Sublimation
María José Colmenares, Edwin A. Bergin, Ke Zhang +27
We present JWST/MIRI-MRS observations of ISO-Oph 37, a highly inclined flat-spectrum (1 Myr old) source, to investigate the chemical composition and dynamical origin of i…
How leaky? A large parameter study of leaky dust traps to quantify the transport of pebbles and ice in protoplanetary discs
Adrien Houge, Anders Johansen, Andrea Banzatti +1
In protoplanetary discs, the presence of dust traps can significantly alter the transport of solids from the outer to the inner regions, and hence they are often invoked as an expl…
Dust and Water in V883 Ori: Relics of a Retreating Snowline
Yu Wang, Chris W. Ormel, Hao-Chang Jiang +3
V883 Ori is an FU-Orionis-type outburst system characterized by a shoulder at 50-70 au in its ALMA band 6 and 7 intensity profiles. Previously, this feature was attributed to dust…
Locked In Ice: how Pebble Drift and Volatile Entrapment can Significantly Impact Carbon and Oxygen Ratios in Evolving Protoplanetary Discs
Joe Williams, Sebastiaan Krijt, Bertram Bitsch +2
The complex interplay between the growth, drift, and sublimation of ice-covered pebbles can strongly influence the volatile distribution and evolution of disc composition, and ther…
Cosmic cascades: How disk substructure regulates the flow of water to inner planetary systems
Sebastiaan Krijt, Andrea Banzatti, Ke Zhang +17
The influx of icy pebbles to the inner regions of protoplanetary disks constitutes a fundamental ingredient in most planet formation theories. The observational determination of th…
Burned to ashes: How the thermal decomposition of refractory organics in the inner protoplanetary disc impacts the gas-phase C/O ratio
Adrien Houge, Anders Johansen, Edwin Bergin +5
The largest reservoir of carbon in protoplanetary discs is stored in refractory organics, which thermally decompose into the gas-phase at the organics line, well interior to the wa…
Coordinated Space and Ground-Based Monitoring of Accretion Bursts in a Protoplanetary Disk: Establishing Mid-Infrared Hydrogen Lines as Accretion Diagnostics for JWST-MIRI
Benjamin M. Tofflemire, Carlo F. Manara, Andrea Banzatti +17
In this paper, we establish and calibrate mid-infrared hydrogen recombination lines observed with JWST as accretion tracers for pre-main-sequence stars that accrete from circumstel…
Smuggling unnoticed: Towards a 2D view of water and dust delivery to the inner regions of protoplanetary discs
Adrien Houge, Sebastiaan Krijt, Andrea Banzatti +6
Infrared spectroscopy, e.g., with JWST, provides a glimpse into the chemical inventory of the innermost region of protoplanetary discs, where terrestrial planets eventually form. T…
The First JWST View of a 30-Myr-old Protoplanetary Disk Reveals a Late-stage Carbon-rich Phase
Feng Long, Ilaria Pascucci, Adrien Houge +20
We present a JWST MIRI/MRS spectrum of the inner disk of WISE J044634.16262756.1B (hereafter J0446B), an old (34 Myr) M4.5 star but with hints of ongoing accretion. The sp…
Into the thick of it: ALMA 0.45 mm observations of HL Tau at 2 au resolution
Osmar M. Guerra-Alvarado, Carlos Carrasco-González, Enrique Macías +7
Aims. To comprehend the efficiency of dust evolution within protoplanetary disks, it is crucial to conduct studies of these disks using high-resolution observations at multiple wav…
Surviving the Heat: multi-wavelength analysis of V883 Ori reveals that dust aggregates survive the sublimation of their ice mantles
Adrien Houge, Enrique Macías, Sebastiaan Krijt
Investigating the response of icy dust aggregates to water ice sublimation is essential for understanding the formation and properties of planetesimals in protoplanetary discs. How…
Collisional evolution of dust and water ice in protoplanetary discs during and after an accretion outburst
Adrien Houge, Sebastiaan Krijt
Most protoplanetary discs are thought to undergo violent and frequent accretion outbursts, during which the accretion rate and central luminosity are elevated for several decades.…
