X-shooter survey Across Regions and Ages to probe Disk Evolution (ARADE): Accretion properties in Orion A and their relation with disk masses
Lara Piscarreta, Giacomo Beccari, Carlo Manara +10
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…
PENELLOPE: IX. Lithium, iron and barium elemental abundances in eight nearby young clusters
R. Carini, K. Biazzo, A. Frasca +19
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…
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…
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…
The ODYSSEUS Survey. Motivation and First Results: Accretion, Ejection, and Disk Irradiation of CVSO 109
C. C. Espaillat, G. J. Herczeg, T. Thanathibodee +59
The Hubble UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Director's Discretionary Program of low-mass pre-main-sequence stars, coupled with forthcoming data fro…
The Evolution Of The Inner Regions of Protoplanetary Disks
Ezequiel Manzo-Martínez, Nuria Calvet, Jesús Hernández +6
We present a study of the evolution of the inner few astronomical units of protoplanetary disks around low-mass stars. We consider nearby stellar groups with ages spanning from 1 t…
Complex Magnetospheric Accretion Flows in Low Accretor CVSO 1335
Thanawuth Thanathibodee, Nuria Calvet, James Muzerolle +3
Although the magnetospheric accretion model has been extensively applied to T Tauri Stars with typical mass accretion rates, the very low accretion regime is still not fully explor…
A transitional disk around an intermediate mass star in the sparse population of the Orion OB1 Association
Alice Pérez-Blanco, Karina Maucó, Jesús Hernández +8
We present a detailed study of the disk around the intermediate mass star SO 411, aiming to explain the spectral energy distribution of this star. We show that this is a transition…
The Evolution of Protoplanetary Disks: Probing the Inner Disk of Very Low Accretors
Thanawuth Thanathibodee, Nuria Calvet, Gregory Herczeg +7
We report FUV, optical, and NIR observations of three T Tauri stars in the Orion OB1b subassociation with H equivalent widths consistent with low or absent accretion and various…
