Protoplanetary and debris disks in the Chamaeleontis Association: A sub-millimeter survey obtained with APEX/LABOCA
V. Roccatagliata, A. Sicilia-Aguilar, M. Kim +7
Nearby associations are ideal regions to study coeval samples of protoplanetary and debris disks down to late M-type stars. Those aged 5-10,Myrs, where most of the disk should have…
Stable accretion in young stars: The cases of EX Lupi and TW Hya
A. Sicilia-Aguilar, J. Campbell-White, V. Roccatagliata +8
We examine the long-term spectroscopic and photometric variability of EX~Lupi and TW~Hya, studying the presence of stable accretion and the role it plays in the observed variabilit…
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…
Twenty-Five Years of Accretion onto the Classical T Tauri Star TW Hya
Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati +39
Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time…
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…
The Radial Distribution and Excitation of H2 around Young Stars in the HST-ULLYSES Survey
Kevin France, Nicole Arulanantham, Erin Maloney +8
The spatial distribution and evolution of gas in the inner 10 au of protoplanetary disks form the basis for estimating the initial conditions of planet formation. Among the most im…
PENELLOPE IV. A comparison between optical forbidden lines and UV lines in the Orion OB1b and -Ori associations
M. Gangi, B. Nisini, C. F. Manara +17
Observing the spatial distribution and excitation processes of atomic and molecular gas in the inner regions (< 20 au) of young (< 10 Myr) protoplanetary disks helps us to understa…
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…
A survey for variable young stars with small telescopes: VI -- Analysis of the outbursting Be stars NSW284, Gaia19eyy, and VES263
Dirk Froebrich, Lynne A. Hillenbrand, Carys Herbert +44
This paper is one in a series reporting results from small telescope observations of variable young stars. Here, we study the repeating outbursts of three likely Be stars based on…
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…
