MINDS survey of silicates in T Tauri disks: Correlation between dust and gas
J. Varga, Th. Henning, L. B. F. M. Waters +20
Context. Silicates are key constituents of planet-forming disks and major building blocks of rocky planets. Mid-infrared spectral features of micron-sized silicate grains trace gra…
JWST Reveals Carbon-rich Chemistry in a Transitional Disk
M. Volz, C. C. Espaillat, C. V. Pittman +6
We present JWST-MIRI Medium Resolution Spectrometer (MRS) observations of the Classical T Tauri stars GM Aur and RX J1615.3-3255 (J1615), both hosting transitional disks. Despite t…
MINDS. Cha Hα 1, a brown dwarf with a hydrocarbon-rich disk
María Morales-Calderón, Hyerin Jang, Aditya M. Arabhavi +23
Context. Recent JWST observations have shown that brown dwarfs (BD) are chemically rich, offering valuable insights into giant planet formation. Aims. As part of the MIRI mid-INfra…
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…
MINDS: Mid-infrared atomic and molecular hydrogen lines in the inner disk around a low-mass star
Riccardo Franceschi, Thomas Henning, Benoît Tabone +27
This work aims to measure the mass accretion rate, the accretion luminosity, and more generally the physical conditions of the warm emitting gas in the inner disk of the very low-m…
XUE. Molecular inventory in the inner region of an extremely irradiated Protoplanetary Disk
María Claudia Ramirez-Tannus, Arjan Bik, Lars Cuijpers +24
We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, that focuses on the characterization of planet forming disks in massive…
Full L- and M-band high resolution spectroscopy of the S CrA binary disks with VLT-CRIRES+
Sierra L. Grant, Giulio Bettoni, Andrea Banzatti +7
The Cryogenic IR echelle Spectrometer (CRIRES) instrument at the Very Large Telescope (VLT) was in operation from 2006 to 2014. Great strides in characterizing the inner regions of…
The -- relationship for Herbig Ae/Be stars: a lifetime problem for disks with low masses?
Sierra L. Grant, Lucas M. Stapper, Michiel R. Hogerheijde +3
The accretion of material from protoplanetary disks onto their central stars is a fundamental process in the evolution of these systems and a key diagnostic in constraining the dis…
MINDS. The detection of CO with JWST-MIRI indicates abundant CO in a protoplanetary disk
Sierra L. Grant, Ewine F. van Dishoeck, Benoît Tabone +43
We present JWST-MIRI MRS spectra of the protoplanetary disk around the low-mass T Tauri star GW Lup from the MIRI mid-INfrared Disk Survey (MINDS) GTO program. Emission from $^{12}…
Scanning disk rings and winds in CO at 0.01-10 au: a high-resolution -band spectroscopy survey with IRTF-iSHELL
Andrea Banzatti, Kirsten M. Abernathy, Sean Brittain +11
We present an overview and first results from a -band spectroscopic survey of planet-forming disks performed with iSHELL on IRTF, using two slits that provide resolving power R…
Tracing Accretion onto Herbig Ae/Be Stars Using the Brγ Line
Sierra L. Grant, Catherine C. Espaillat, Sean Brittain +2
Accretion plays an important role in protoplanetary disk evolution, and it is thought that the accretion mechanism changes between low- and high-mass stars. Here, we characterize a…
An ALMA Survey of Protoplanetary Disks in Lynds 1641
Sierra L. Grant, Catherine C. Espaillat, John Wendeborn +8
We present ALMA observations of 101 protoplanetary disks within the star-forming region Lynds 1641 in the Orion Molecular Cloud A. Our observations include 1.33 mm continuum emissi…
Using Multiwavelength Variability to Explore the Connection between X-ray Emission, the Far-Ultraviolet H2 Bump, and Accretion in T Tauri Stars
C. C. Espaillat, C. Robinson, S. Grant +1
The high-energy radiation fields of T Tauri stars (TTS) should affect the surrounding circumstellar disk, having implications for disk transport and heating. Yet, observational evi…
Herschel Observations of Protoplanetary Disks in Lynds 1641
Sierra L. Grant, Catherine C. Espaillat, S. Thomas Megeath +7
We analyze Herschel Space Observatory observations of 104 young stellar objects with protoplanetary disks in the ~1.5 Myr star-forming region Lynds 1641 (L1641) within the Orion A…
