Protoplanetary disk cavities with JWST-MIRI: a dichotomy in molecular emission
Patrick Mallaney, Andrea Banzatti, Colette Salyk +24
The evolution of planet-forming regions in protoplanetary disks is of fundamental importance to understanding planet formation. Disks with a central deficit in dust emission, a "ca…
The Flying Saucer edge-on disc's Near Infrared silhouette revealed by the JWST JEDIce program
Emmanuel Dartois, Jennifer A. Noble, Jennifer B. Bergner +17
Edge-on discs offer a unique opportunity to probe radial and vertical dust and gas distributions in the protoplanetary phase. This study aims to investigate the distribution of mic…
An Ancient Brown Dwarf Transiting a Metal-Poor Thick Disk Star
Jéa Adams Redai, Vedant Chandra, Samuel W. Yee +20
We report the discovery of TOI-7019b, the first transiting brown dwarf (BD) known to orbit a star that is part of the Milky Way's ancient thick disk, as defined chemically ([Fe/H]…
High CO/H2 ratios supports an exocometary origin for a CO-rich debris disk
Kevin D. Smith, Luca Matrà, Ke Zhang +9
Over 20 exocometary belts host detectable circumstellar gas, mostly in the form of CO. Two competing theories for its origin have emerged, positing the gas to be primordial or seco…
REsolved ALMA and SMA Observations of Nearby Stars (REASONS): A population of 74 resolved planetesimal belts at millimetre wavelengths
L. Matrà, S. Marino, D. J. Wilner +19
Planetesimal belts are ubiquitous around nearby stars, and their spatial properties hold crucial information for planetesimal and planet formation models. We present resolved dust…
Characterising the molecular line emission in the asymmetric Oph-IRS 48 dust trap: Temperatures, timescales, and sub-thermal excitation
Milou Temmink, Alice S. Booth, Margot Leemker +8
The ongoing physical and chemical processes in planet-forming disks set the stage for planet formation. The asymmetric disk around the young star Oph-IRS 48 has one of the most wel…
Water in protoplanetary disks with JWST-MIRI: spectral excitation atlas and radial distribution from temperature diagnostic diagrams and Doppler mapping
Andrea Banzatti, Colette Salyk, Klaus M. Pontoppidan +19
This work aims at providing fundamental general tools for the analysis of water spectra as observed in protoplanetary disks with JWST-MIRI. We analyze 25 high-quality spectra from…
ALMA high-resolution observations unveil planet formation shaping molecular emission in the PDS 70 disk
L. Rampinelli, S. Facchini, M. Leemker +7
With two directly detected protoplanets, the PDS 70 system is a unique source in which to study the complex interplay between forming planets and their natal environment. The large…
On the Ubiquity and Stellar Luminosity Dependence of Exocometary CO Gas: Detection around M Dwarf TWA 7
Luca Matrà, Karin I. Öberg, David J. Wilner +2
Millimeter observations of CO gas in planetesimal belts show a high detection rate around A stars, but few detections for later type stars. We present the first CO detection in a p…
Variable HCO Emission in the IM Lup Disk: X-ray Driven Time-Dependent Chemistry?
L. Ilsedore Cleeves, Edwin A. Bergin, Karin I. Öberg +3
We report the first detection of a substantial brightening event in an isotopologue of a key molecular ion, HCO, within a protoplanetary disk of a T Tauri star. The HCO$…
The Radial Distribution of H2 and CO in TW Hya as Revealed by Resolved ALMA Observations of CO Isotopologues
Kamber R. Schwarz, Edwin A. Bergin, L. Ilsedore Cleeves +5
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 quantify th…
Laboratory Astrophysics White Paper (based on the 2010 NASA Laboratory Astrophysics Workshop in Gatlinberg, Tennessee, 25-28 October 2010)
Daniel Wolf Savin, Lou Allamandola, Steve Federman +7
The purpose of the 2010 NASA Laboratory Astrophysics Workshop (LAW) was, as given in the Charter from NASA, "to provide a forum within which the scientific community can review the…
