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…
X-Shooter survey of disk accretion in Upper Scorpius II. A lack of correlation between accretion rates and disk properties
A. Empey, C. F. Manara, R. Garcia Lopez +19
The evolution of protoplanetary discs is intertwined with the process of planet formation, growth and migration. Studies of nearby star forming regions of different ages and proper…
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…
Characterisation of an EXor outburst SPICY 97589
Aaron Labdon, Rik Claes
Stellar outbursts from variable or periodic accretion are thought to be ubiquitous across young stellar populations. However, relatively few outbursting objects have been discovere…
The dance of dust: Investigating young stellar object dipper variability
A. Empey, R. Garcia Lopez, A. Natta +4
The dipper subclass of YSOs are characterised by frequent dips in their light curves. Irregular dippers do not show periodic signatures and have dips accounting for significant pro…
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…
Probing accretion and stellar properties in the Orion Nebula with VLT/X-Shooter
L. Piscarreta, G. Beccari, R. A. B. Claes +6
Multiple photometric studies have reported the presence of seemingly older accreting pre-main sequence stars (PMS) in optical colour-magnitude diagrams (CMDs). We investigate this…
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 accretion luminosity of Class I protostars
L. Testi, A. Natta, S. Gozzi +7
The value of the accretion luminosity during the early phases of star formation is a crucial information which helps us understand how stars form, yet it is still very difficult to…
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…
Evolution of the relation between the mass accretion rate and the stellar and disk mass from brown dwarfs to stars
V. Almendros-Abad, C. F. Manara, L. Testi +7
The time evolution of the dependence of the mass accretion rate with the stellar mass and the disk mass represents a fundamental way to understand the evolution of protoplanetary d…
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…
Testing external photoevaporation in the -Orionis cluster with spectroscopy and disk mass measurements
K. Maucó, C. F. Manara, M. Ansdell +8
The evolution of protoplanetary disks is regulated by an interplay of several processes, either internal to the system or related to the environment. As most of the stars and plane…
A magnetically driven disc wind in the inner disc of PDS 70
Justyn Campbell-White, Carlo F. Manara, Myriam Benisty +10
PDS 70 is so far the only young disc where multiple planets have been detected by direct imaging. The disc has a large cavity when seen at sub-mm and NIR wavelengths, which hosts t…
Brightness and mass accretion rate evolution during the 2022 burst of EX~Lupi
F. Cruz-Sáenz de Miera, Á. Kóspál, P. Ábrahám +18
EX Lupi is the prototype by which EXor-type outbursts were defined. It has experienced multiple accretion-related bursts and outbursts throughout the last decades, whose study have…
Empirical Determination of the Lithium 6707.856 Å Wavelength in Young Stars
Justyn Campbell-White, Carlo F. Manara, Aurora Sicilia-Aguilar +20
Absorption features in stellar atmospheres are often used to calibrate photocentric velocities for kinematic analysis of further spectral lines. The Li feature at 6708 Å is…
Lyman-alpha Scattering Models Trace Accretion and Outflow Kinematics in T Tauri Systems
Nicole Arulanantham, Max Gronke, Eleonora Fiorellino +18
T Tauri stars produce broad Lyman-alpha emission lines that contribute 88% of the total UV flux incident on the inner circumstellar disks. Lyman-alpha photons are generated a…
PENELLOPE III. The peculiar accretion variability of XX Cha and its impact on the observed spread of accretion rates
R. A. B. Claes, C. F. Manara, R. Garcia-Lopez +17
The processes regulating protoplanetary disk evolution are constrained by studying how mass accretion rates scale with stellar and disk properties. The spread in these relations ca…
