The cosmic DANCe of Perseus I: Membership, phase-space structure, mass, and energy distributions
J. Olivares, H. Bouy, N. Miret-Roig +4
Context. Star-forming regions are excellent benchmarks for testing and validating theories of star formation and stellar evolution. The Perseus star-forming region being one of the…
The SPHERE view of three interacting twin disc systems in polarised light
Philipp Weber, Sebastián Pérez, Greta Guidi +12
Dense stellar environments as hosts of ongoing star formation increase the probability of gravitational encounters among stellar systems during the early stages of evolution. Stell…
Modeling the CO outflow in DG Tau B: Swept-up shells versus perturbed MHD disk wind
A. de Valon, C. Dougados, S. Cabrit +3
The origin of outflows and their exact impact on disk evolution and planet formation remain crucial open questions. DG Tau B is a Class I protostar associated with a rotating conic…
A low-mass companion desert among intermediate-mass visual binaries: The scaled-up counterpart to the brown dwarf desert
G. Duchene, J. T. Oon, R. J. De Rosa +8
We present a high-contrast imaging survey of intermediate-mass (1.75--4.5 ) stars to search for the most extreme stellar binaries, i.e., for the lowest mass stellar compan…
The GRAVITY Young Stellar Object survey -- IX. Spatially resolved kinematics of hot hydrogen gas in the star/disk interaction region of T Tauri stars
GRAVITY Collaboration, J. A. Wojtczak, L. Labadie +58
Aims: We aim to spatially and spectrally resolve the Br-gamma hydrogen emission line with the methods of interferometry in order to examine the kinematics of the hydrogen gas emiss…
Accretion process, magnetic fields, and apsidal motion in the pre-main sequence binary DQ Tau
Kim Pouilly, Oleg Kochukhov, Ágnes Kóspál +3
Classical T Tauri stars (CTTSs) are young stellar objects that accrete materials from their accretion disc influenced by their strong magnetic field. The magnetic pressure truncate…
The Small Separation A-Star Companion Population: First Results with CHARA/MIRC-X
Matthew De Furio, Tyler Gardner, John Monnier +9
We present preliminary results from our long-baseline interferometry (LBI) survey to constrain the multiplicity properties of intermediate-mass A-type stars within 80pc. Previous m…
Connecting photometric and spectroscopic granulation signals with CHEOPS and ESPRESSO
S. Sulis, M. Lendl, H. Cegla +83
Stellar granulation generates fluctuations in photometric and spectroscopic data whose properties depend on the stellar type, composition, and evolutionary state. In this study, we…
The Orbits and Dynamical Masses of the Castor System
Guillermo Torres, Gail H. Schaefer, John D. Monnier +12
Castor is a system of six stars in which the two brighter objects, Castor A and B, revolve around each other every 450 yr and are both short-period spectroscopic binaries. Th…
Radiation-driven acceleration in the expanding WR140 dust shell
Yinuo Han, Peter G. Tuthill, Ryan M. Lau +1
The Wolf-Rayet (WR) binary system WR140 is a close (0.9-16.7 mas) binary star consisting of an O5 primary and WC7 companion and is known as the archetype of episodic dust-producing…
Nested Dust Shells around the Wolf-Rayet Binary WR 140 observed with JWST
Ryan M. Lau, Matthew J. Hankins, Yinuo Han +29
Massive colliding-wind binaries that host a Wolf-Rayet (WR) star present a potentially important source of dust and chemical enrichment in the interstellar medium (ISM). However, t…
Dynamical masses of the primary Be star and the secondary sdB star in the single-lined binary kappa Dra (B6 IIIe)
R. Klement, D. Baade, Th. Rivinius +16
Because many classical Be stars may owe their nature to mass and angular-momentum transfer in a close binary, the present masses, temperatures, and radii of their components are of…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): Scattered light detection of a possible disk wind in RY Tau
P. -G. Valegård, C. Ginski, C. Dominik +14
Disk winds are an important mechanism for accretion and disk evolution around young stars. The accreting intermediate-mass T-Tauri star RY Tau has an active jet and a previously kn…
Sustained FU Orionis-type outbursts from colliding discs in stellar flybys
Elisabeth M. A. Borchert, Daniel J. Price, Christophe Pinte +1
We perform 3D hydrodynamics simulations of disc-disc stellar flybys with on-the-fly Monte Carlo radiative transfer. We show that pre-existing circumstellar discs around both stars…
A HARPS radial velocity search for planets in the Scorpius-Centaurus association. And its combination with the HARPS and SOPHIE young nearby stars (YNS) surveys
Antoine Grandjean, A. -M. Lagrange, N. Meunier +13
The Scorpius-Centaurus (Sco-Cen) young and nearby massive star-forming region is particularly well suited for extrasolar planet searches with both direct imaging and radial velocit…
Investigating 2M1155-7919B: a Nearby, Young, Low-Mass Star Actively Accreting from a Nearly Edge-on, Dusty Disk
D. Annie Dickson-Vandervelde, Joel H. Kastner, Jonathan Gagné +5
We investigate the nature of an unusually faint member of the Cha Association ( pc, age Myr), the nearest region of star formation of age 8 Myr. This objec…
