The Physical Properties of the SVS 13 Protobinary System: Two Circumstellar Disks and a Spiraling Circumbinary Disk in the Making
Ana K. Diaz-Rodriguez, Guillem Anglada, Guillermo Blázquez-Calero +13
We present VLA and ALMA observations of the close (0.3" = 90 au separation) protobinary system SVS 13. We detect two small circumstellar disks (radii 12 and 9 au in dus…

Violeta Gamez Rosas, Jacob W. Isbell, Walter Jaffe +49
In the widely accepted 'Unified Model' solution of the classification puzzle of Active Galactic Nuclei, the orientation of a dusty accretion torus around the central black hole dom…
Triton Haze Analogues: the Role of Carbon Monoxide in Haze Formation
Sarah E. Moran, Sarah M. Hörst, Chao He +7
Triton is the largest moon of the Neptune system and possesses a thin nitrogen atmosphere with trace amounts of carbon monoxide and methane, making it of similar composition to tha…
Probing the low-mass end of the companion mass function for O-type stars
M. Reggiani, A. Rainot, H. Sana +6
Almost all massive stars are part of a binary system. Given the wide range of separations at which these companions are found, several observational techniques have been adopted to…
The extended atmosphere and circumstellar environment of the cool evolved star VX Sagittarii as seen by MATISSE
A. Chiavassa, K. Kravchenko, M. Montargès +50
Context. VX Sgr is a cool, evolved, and luminous red star whose stellar parameters are difficult to determine, which affects its classification. Aims. We aim to spatially resolve t…
Short time-scale X-ray spectral variability in the Seyfert 1 galaxy NGC 3783
D. Costanzo, M. Dadina, C. Vignali +9
We report on the X-ray time resolved spectral analysis of XMM-Newton observations of NGC 3783. The main goal is to detect transient features in the Fe K line complex, in order to s…
The relativistic parsec-scale jets of the blazars TXS 0506+056 and PKS 0502+049 and their possible association with gamma-ray flares and neutrino production
Viktor Y. D. Sumida, André de A. Schutzer, Anderson Caproni +1
The physical nature of the mechanism responsible for the emission of neutrinos in active galactic nuclei (AGN) has been matter of debate in the literature, with relativistic jets o…
ALMA-IMF I -- Investigating the origin of stellar masses: Introduction to the Large Program and first results
F. Motte, S. Bontemps, T. Csengeri +61
The ALMA-IMF Large Program imaged a total noncontiguous area of 53pc2, covering 15 extreme, nearby protoclusters of the Milky Way. They were selected to span relevant early protocl…
Estimating fundamental parameters of nearby M dwarfs from SPIRou spectra
P. I. Cristofari, J. -F. Donati, T. Masseron +10
We present the results of a study aiming at retrieving the fundamental parameters of M dwarfs from spectra secured with SPIRou, the near-infrared high-resolution spectropolarimeter…
Organic chemistry in the protosolar analogue HOPS-108: Environment matters
L. Chahine, A. López-Sepulcre, R. Neri +10
Hot corinos are compact regions around solar-mass protostellar objects that are very rich in interstellar complex organic molecules (iCOMs). They are believed to represent the very…
The Spatial Evolution of Young Massive Clusters III. Effect of the Gaia Filter on 2D Spatial Distribution Studies
Anne S. M. Buckner, Zeinab Khorrami, Marta González +3
[Context.] Gaia is limited in the optical down to G~21 mag so it is essential to understand the biases introduced by a magnitude-limited sample on spatial distribution studies. [Ai…
The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits
GRAVITY Collaboration, R. Abuter, N. Aimar +62
The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…
Deep Images of the Galactic Center with GRAVITY
GRAVITY Collaboration, R. Abuter, N. Aimar +65
Stellar orbits at the Galactic Center provide a very clean probe of the gravitational potential of the supermassive black hole. They can be studied with unique precision, beyond th…
The protoplanetary disc around HD 169142: circumstellar or circumbinary?
P. P. Poblete, N. Cuello, S. Pérez +12
Stellar binaries represent a substantial fraction of stellar systems, especially among young stellar objects. Accordingly, binaries play an important role in setting the architectu…
BEBOP III. Observations and an independent mass measurement of Kepler-16 (AB) b -- the first circumbinary planet detected with radial velocities
Amaury H. M. J. Triaud, Matthew R. Standing, Neda Heidari +30
The radial velocity method is amongst the most robust and most established means of detecting exoplanets. Yet, it has so far failed to detect circumbinary planets despite their rel…
On the rise times in FU Orionis events
Elisabeth M. A. Borchert, Daniel J. Price, Christophe Pinte +1
We examine whether stellar flyby simulations can initiate FU Orionis outbursts using 3D hydrodynamics simulations coupled to live Monte Carlo radiative transfer. We find that a fly…
Dynamical masses for two M1 + mid-M dwarf binaries monitored during the SPHERE-SHINE survey
Beth A. Biller, Antoine Grandjean, Sergio Messina +25
We present orbital fits and dynamical masses for HIP 113201AB and HIP 36985AB, two M1 + mid-M dwarf binary systems monitored as part of the SPHERE SHINE survey. To robustly determi…
Galactic Star Formation with NIKA2 (GASTON): Evidence of mass accretion onto dense clumps
A. J. Rigby, R. Adam, P. Ade +49
High-mass stars () play a crucial role in the evolution of galaxies, and so it is imperative that we understand how they are formed. We have used the New…
Interferometric detections of sdO companions orbiting three classical Be stars
R. Klement, G. H. Schaefer, D. R. Gies +17
Classical Be stars are possible products of close binary evolution, in which the mass donor becomes a hot, stripped O or B-type subdwarf (sdO/sdB), and the mass gainer spins up and…
