An interferometric mid-infrared study of the eruptive star binary Z CMa with MATISSE/VLTI. I. Imaging the protoplanetary disks during the 2023 outburst
F. Lykou, J. Varga, F. Cruz-Saénz de Miera +14
The mid-infrared (MIR) emitting regions of the individual protoplanetary disks in the binary system Z CMa are resolved by MATISSE/VLTI. The observations were obtained during a sere…
T CrA has a companion: First direct detection of T CrA B with VLTI/MATISSE
J. Varga, A. Matter, F. Millour +21
T CrA is a Herbig Ae-type young star in a complex circumstellar environment; it includes a circumstellar disk, accretion streamers, jets, and outflows. It has long been suspected t…
Evidence for an accretion bridge in the DX Cha circumbinary system from VLTI/MATISSE observations
Tímea Juhász, József Varga, Péter Ábrahám +20
DX Cha (HD 104237) is a spectroscopic binary consisting of a Herbig A7.5Ve-A8Ve primary star and a K3-type companion. Here we report on new micrometer interferometric observ…
The accretion burst of the massive young stellar object G323.46 -0.08
V. Wolf, B. Stecklum, A. Caratti o Garatti +10
Accretion bursts from low-mass young stellar objects (YSOs) are known for many decades. In recent years, the first accretion bursts of massive YSOs (MYSOs) have been observed. Thes…
Mid-infrared evidence for iron-rich dust in the multi-ringed inner disk of HD 144432
J. Varga, L. B. F. M. Waters, M. Hogerheijde +40
Context. Rocky planets form by the concentration of solid particles in the inner few au regions of planet-forming disks. Their chemical composition reflects the materials in the di…
Study of the bipolar jet of the YSO Th 28 with VLT/SINFONI: Jet morphology and H emission
S. Yu. Melnikov, P. A. Boley, N. S. Nikonova +5
The YSO Th 28 possesses a highly collimated jet, which clearly exhibits an asymmetric brightness of its jet lobes at optical and NIR wavelengths. There may be asymmetry…
A Detailed View of the Circumstellar Environment and Disk of the Forming O-star AFGL 4176
K. G. Johnston, M. G. Hoare, H. Beuther +5
We present a detailed analysis of the disk and circumstellar environment of the forming O-type star AFGL 4176 mm1, placing results from the Atacama Large Millimeter/submillimeter A…
New high-resolution near-infrared observations of the asymmetric jet of the massive young stellar object G192.16-3.82
Paul A. Boley, Hendrik Linz, Nadezhda Dmitrienko +6
The process of massive star formation is tightly connected with the appearance of molecular outflows, which interact with surrounding interstellar medium and can be used as a proxy…
Spiral arms and instability within the AFGL 4176 mm1 disc
K. G. Johnston, M. G. Hoare, H. Beuther +7
We present high-resolution (30 mas or 130 au at 4.2 kpc) Atacama Large Millimeter/submillimeter Array observations at 1.2 mm of the disc around the forming O-type star AFGL 4176 mm…
Molecular envelope around the HII region RCW 120
M. S. Kirsanova, Ya N. Pavlyuchenkov, D. S. Wiebe +5
The H II region RCW120 is a well-known object, which is often considered as a target to verify theoretical models of gas and dust dynamics in the interstellar medium. However, the…
Resolving the MYSO binaries PDS 27 and PDS 37 with VLTI/PIONIER
E. Koumpia, K. M. Ababakr, W. J. de Wit +7
Binarity and multiplicity appear to be a common outcome in star formation. In particular, the binary fraction of massive (OB-type) stars can be very high. In many cases, the furthe…
