We present a homogeneous VLT/X-Shooter study of accretion in young stellar objects spanning the entire Orion A complex. Our sample includes 91 pre-main-sequence stars hosting a pro…
JWST-MIRI's multi-dimensional view of mass loss in the irradiated disks of NGC 1977
Alice S. Booth, Qijia Zhou, Jinyoung Serena Kim +10
The evolution of protoplanetary disks, and consequently the outcomes of planet formation, are thought to be significantly altered in regions containing massive stars. Extreme cases…

We conducted a homogeneous chemical analysis of pre-main sequence stars with effective temperatures ranging from 3000 K to 5500 K in eight nearby star-forming regions…
PENELLOPE VII: Revisiting empirical relations to measure accretion luminosity
E. Fiorellino, J. M. Alcalá, C. F. Manara +10
The accretion luminosity (Lacc) in young, low-mass stars is crucial for understanding stellar formation, but direct measurements are often hindered by limited spectral coverage and…
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 centimeter emission from planet-forming disks in Taurus
Antonio Garufi, Carlos Carrasco-Gonzalez, Enrique Macias +16
The last decade has witnessed remarkable advances in the characterization of the (sub-)millimeter emission from planet-forming disks. Instead, the study of the (sub-)centimeter emi…
Substellar candidates at the earliest stages: the SUCANES database
A. M. Pérez-García, N. Huélamo, A. García-López +11
Brown dwarfs are the bridge between low-mass stars and giant planets. One way of shedding light on their dominant formation mechanism is to study them at the earliest stages of the…
A tell-tale tracer for externally irradiated protoplanetary disks: comparing the [CI] 8727 A line and ALMA observations in proplyds
Mari-Liis Aru, Karina Mauco, Carlo F. Manara +15
The evolution of protoplanetary disks in regions with massive OB stars is influenced by externally driven winds that deplete the outer parts of disks. These winds have previously b…
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…
Rotational Evolution of Classical T Tauri Stars: Models and Observations
Javier Serna, Giovanni Pinzón, Jesús Hernández +17
We developed a grid of stellar rotation models for low-mass and solar-type Classical T Tauri stars (CTTS) (). These models incorporate the star-…
Spectroscopic confirmation of high-amplitude eruptive YSOs and dipping giants from the VVV survey
Zhen Guo, P. W. Lucas, R. Kurtev +17
During the pre-main-sequence (pre-MS) evolution stage of a star, significant amounts of stellar mass are accreted during episodic accretion events, such as multi-decade FUor-type o…
PENELLOPE V. The magnetospheric structure and the accretion variability of the classical T Tauri star HM Lup
A. Armeni, B. Stelzer, R. A. B. Claes +9
HM Lup is a young M-type star that accretes material from a circumstellar disk through a magnetosphere. Our aim is to study the inner disk structure of HM Lup and to characterize i…
The vertical structure of debris disks and the impact of gas
Johan Olofsson, Philippe Thébault, Quentin Kral +10
The vertical structure of debris disks provides clues about their dynamical evolution and the collision rate of the unseen planetesimals. Thanks to the ever-increasing angular reso…
A Census of the Low Accretors. I: The Catalog
Thanawuth Thanathibodee, Nuria Calvet, Jesus Hernandez +2
Observations have shown that the disk frequency and the fraction of accreting pre-main-sequence stars decrease with the age of the population and that some stars appear to have dis…
