Modeling the curved dust sublimation front in protoplanetary disks: a potential probe of midplane turbulence
Ezequiel Manzo-Martínez, Ramiro Franco-Hernández, Nuria Calvet +3
We present a new approach to calculate the geometry and emission of the dust inner wall in disks around T Tauri stars. This calculation follows a self-consistent approach given the…
Understanding Balmer Decrements in T Tauri stars in terms of Multiflow Magnetospheric Accretion
Naiara Patiño, Nuria Calvet, Gladis Magris +4
Magnetospheric accretion is the paradigm for accretion in Classical T-Tauri Stars (CTTS). However, the standard, one-flow magnetospheric accretion model fails to replicate importan…
AREPAS: A Resource for Exploring Protostellar Accretion Systems - Data Release I
Marbely Micolta, Thanawuth Thanathibodee, Katya Gozman +1
We present AREPAS, a visualization tool for the exploration of the first data release of the open library of magnetospheric accretion models for T Tauri Stars. The dataset covers t…
Accretion onto the Embedded Protostar L1527 IRS: Insights from JWST NIRSpec and MIRI Observations
W. Blake Drechsler, John J. Tobin, Patrick D. Sheehan +12
Accretion is the primary driver of protostellar evolution, regulating mass assembly and shaping the physical and chemical environments of young stellar objects. Quantifying accreti…
Indications of Rapid Dust Formation in the Inner Region of a Protoplanetary Disk
Thanawuth Thanathibodee, Catherine Espaillat, Nuria Calvet +4
We report a significant increase in mid-infrared emission m in a transitional disk. The 2024 JWST/MIRI observation of the disk around CVSO 1942 reveals flux increase by…
IPA. Accretion rate of a low-mass Class 0 protostar, measured via mid-infrared fluorescent OH emission
Dan M. Watson, Mayank Narang, Caeley V. Pittman +41
The earliest stages of star formation are highlighted by complex interactions between accretion, outflow, and radiative processes, which shape the chemical and physical environment…
The ODYSSEUS Survey. Spatial correlation of magnetospheric inclinations points to parsec-scale star-cloud connection
Caeley V. Pittman, Catherine C. Espaillat, Thanawuth Thanathibodee +3
The properties of stars and planets are shaped by the initial conditions of their natal clouds. However, the spatial scales over which the initial conditions can exert a significan…
The ODYSSEUS Survey. Using accretion and stellar rotation to reveal the star-disk connection in T Tauri stars
Caeley V. Pittman, C. C. Espaillat, Zhaohuan Zhu +4
Classical T Tauri stars (CTTS) exhibit strong variability over timescales of minutes to decades. However, much theoretical work assumes that CTTS are in stable spin states. Here, w…
The ODYSSEUS Survey. Characterizing magnetospheric geometries and hotspot structures in T Tauri stars
Caeley V. Pittman, C. C. Espaillat, Connor E. Robinson +20
Magnetospheric accretion is a key process that shapes the inner disks of T Tauri stars, controlling mass and angular momentum evolution. It produces strong ultraviolet and optical…
The UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Large Director's Discretionary Program with Hubble. I. Goals, Design, and Initial Results
Julia Roman-Duval, William J. Fischer, Alexander W. Fullerton +44
Specifically selected to leverage the unique ultraviolet capabilities of the Hubble Space Telescope, the Hubble Ultraviolet Legacy Library of Young Stars as Essential Standards (UL…
Evidence for Variable Accretion onto PDS 70 c and Implications for Protoplanet Detections
Yifan Zhou, Brendan P. Bowler, Aniket Sanghi +14
Understanding the processes of planet formation and accretion in young systems is essential to unraveling the initial conditions of planetary systems. The PDS 70 system, which host…
Using the Ca II lines in T Tauri stars to infer the abundance of refractory elements in the innermost disk regions
Marbely Micolta, Nuria Calvet, Thanawuth Thanathibodee +5
We present a study of the abundance of calcium in the innermost disk of 70 T Tauri stars in the star-forming regions of Chamaeleon I, Lupus and Orion OB1b. We use calcium as a prox…
A Model of the C IV 1548, 1550 Doublet Line in T Tauri Stars
Thanawuth Thanathibodee, Connor Robinson, Nuria Calvet +7
The C IV doublet in the UV has long been associated with accretion in T Tauri stars. However, it is still unclear where and how the lines are formed. Here, we present a new C IV li…
A Multi-wavelength, Multi-epoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. III. Optical Spectra
John Wendeborn, Catherine C. Espaillat, Thanawuth Thanathibodee +20
Classical T Tauri Stars (CTTSs) are highly variable stars that possess gas- and dust-rich disks from which planets form. Much of their variability is driven by mass accretion from…
